Does anyone know if there are Tube Amps or receivers that can be hooked up to TV's, Tivo, CD players, turntables, etc?

I am interested in tubes, but I use my speakers for everything and dont want to purchase additional speakers just for tube use.

Thank you for any of your help, it is greatly appreciated.

Can I hook up tubes to an existing receiver?

Sorry, I am new to the tube thing.

Just hook the tube amp to the pre-out jacks on the back of your 3380. Then connect your Valencias to the tube amp.

A lot of guys like low powered SET tube amps, I think they are questionable on anything lower than about 105db 1w/1m speakers. I'd personally stay away from the under 10 watt amps with Valencias given their sensitivity. Depends how loud you listen to them though.

What tube amp should I get? Do I only need one or two?

Thanks!

I have heard it will tame the horns on the Altecs, is that true?

If its a mono amp you need 2, if its a stereo amp you only need 1.

Taming horns with tube amps... kind of but not really. You can match up a certain tube amp with a certain speaker and get the interaction to act somewhat like an EQ. I would argue that you are not changing (taming) the speakers physical characteristics but just Eq'ing the frequency response a bit.

Do you use your Tivo, cd players ect through the 3380? I would think getting a mid range receiver ($500ish) would be a better bet. You could use the digital output of your newer devices. The mid range receivers have better DACs which usually sound better than the analog outs of things like cable boxes, game systems and cheap dvd/cd players.

My receiver is only 2 months old.

It is a stereo - 2 channel.

So, I would only need one?

Thank you for your help, I greatly appreciate it.

In your opinion - do you think I should even try tubes or forget it?

The concept is that amps come in mono or stereo form. Some folks buy a pair of single channel amps to get the maximum isolation (separation) between Left and Right channels. But if you are using vintage gear, its twice as many places for old parts that could fail ... Tube gear can also be expensive to own and maintain.

But are you looking to feed the preamp out from your HK receiver into a tube amp?

Storm,

i thought you would know about this. I would advise against using your tube amp for watching tv, as tubes are expensive. My friend does it all the time... runs his tube preamp as a switcher for everything, but i think hes nuts to waste the tube on his tv.

anyway... i can recommend a very nice tube amp in my experience. I had a conrad johnson mv 55. for under 1k, it is a great amp, 45 wpc el34 tubes---should be a nice match for the valencias.

I have heard good things about the quicksilvers, they are reasonably priced but i havent heard them.

The closest thing ive heard to tube magic without the tubes is the fanstastic pass labs aleph 3. Also for under 1k, it was a hellaciously good amplifier. If i didnt have so many toys at the time, i definitely would have held onto it. Some builders can make you an alephclone for probably around 500 bucks custom made to your liking. They are expensive to build because of the massive heatsinking required to keep them cool. You can literally cook an egg on them.

If you have been running your Valencias with a run of the mill reciever then you have completely been missing what your speakers are capable of.

Tubes are the best route to go for home stereo.

Vintage tube gear is better than the new stuff.

Keep your stereo and your "home theatre" seperate.

I prefer mono block but have heard some GREAT stereo tube amps.

Always chill your nice vodka and fresh limes are the best.

You can never go fast enough.

Why the tubes, anyway? Can't you just stuff socks in your horn (Oooh! That sounds so....naughty!) and achieve the same thing? Or cover the entire cabinet with a big towel? You get what you get. That tubes making certain speakers sound better through matching tube amps is really a crude form of hit-and-miss EQ really made the point elegantly and simply. :applaud:

-Lots of Crown transistors for nearly every listening experience
-Soundcraftsmen pre-EQ if I don't like the result
-Mac C20 for when I feel the need for some heat
-Fisher SA-1000 (R.I.P.) from when tubes were too damn much trouble

So, hooking up a tube amp to the receiver won't work?

How much different is the sound coming from tubes rather then SS?

Thanks.

Sure it will work - assuming your receiver has preamp outputs - you just bypass the receiver's output stage that way.

The point is - is the gain worth the trouble?

Storm

Yes, my receiver has those out puts.

Do you think it is not worth the gain?

Am I really not experiencing my speakers' potential?

Thanks.

depends on what you normally listen to Storm....

when I had the Model 19s...

I used to swap between a Hafler DH500 (or simmilar powered solid state) and a Heathkit AA-151 (14WPC, EL84 Mullard based Push Pull tube integrated amp) depending on what I was going to listen to....

early blues, jazz, classical, early rock & roll were all great with the tubes...

electronic dance music and other modern "pop type music" seemed to benefit from the additional power

I enjoy anything from the 60s to the early 90s.

I guess tubes would not be suited for me.

I was only trying to understand the difference between SS and Tubes, because I have only heard good things about tubes and valencias. But, that might be because they listen to the stuff you mentioned.

Thank you for the insight.

I dunno - I gave up on tubes years ago!
But its really a personal thing - its all your tastes ...

BMWCCA said that you can change the sound (tone?) of your audio more easily using EQ than by going to specialized amps.

I'd tend to agree that using a QUALITY EQ (e.g, one that doesn't have noisy gain stages to degrade your overall sound) is probably a better way to change sound. Look at all the stuff Zilch and the rest of them do with RTA (Real Time Analysers) to visually SEE the sound coming out of their speakers and EQ it to fit their tastes better.

Besides - Tubes age - a new tube sounds different than an older tube - and some folks will tell you Russian tubes sound better than vintage RCA or whatever the current flavor is.

Really - everything in audio has "a flavor" (it shouldn't, but usually it does). - the trick is to not gum up the sound by putting too many things in the signal path.

And personally, I try to avoid the more expensive snake oil - its a pricey lesson!

you could try biamping the speakers and pushing the horns with the tubes and using SS on the woofers...

I do that ocassionally, but honestly I like the Altec 802s and JBL 075s better on my Crown D-75s than I do on the heathkit.....


granted, maybe if I wnet and spent too much money on a very very nice old tube amp..... ;)

Ummmm.....

I have been running those Santana's with both my Fisher 500-C tube receiver and a little Pioneer 737 SS unit and of course it sounds better with tubes.

Doncha' have to have a tube-type TV to be able to connect to a tube audio amp? :blink:

Storm, I'm gonna break character briefly and give you the straight doodoo instead of jerking your chain. For your Altecs, you should convert to biamping, period. Ditch the XO and buy a 2-way active crossover. Use whatever SS amp you use now for the 416s, they need the damping of SS in those big, vented boxes. Buy either a couple of monos or a stereo tube amp of modest power (5-20W) to run the horns, where the extra harmonics of tubes has a subjectively pleasing effect. Do this, and then I'll believe you'll keep those Vals for life! Less than $1K ought to get you there nicely, or any amount over that you're willing to pay.

Be aware that tube gear is like a Harley, in that you better keep your tools handy. For a newbie, the only way to start is with an amp you can either go and listen to, or audition for yourself for a few days. 'Restored' is almost always preferrable to 'modified'. I'll bet there's an old geezer near you that restores old gear for fun, and also 'cause he knows how it works. That's the kinda deal you should look for, and if you succeed, remember to be nice to the old guy, after all, he used to know everything too. :p

The Fisher 500-C is rated at 30WPC and the 737 is 35WPC
Both sound good through the Altecs but the Fisher does sound better, of course.

Okay, I thought it was more. My parents had a 400 and I figured it was 30WPC. My SA-1000 was rated at 75W/channel so I guess I got confused. However, at least Peter Breuninger calls the 500-C 35WPC here: http://stereophile.com/historical/605fisher/index.html :dont-know

In my recollection, the D150 felt more powerful than the SA-1000 I traded-in on the Crown, and the DC300 blew them both away, all playing the 030s. But that was 1974 and I couldn't afford the DC300. I still have that D150 though! That was the start of my pooh-poohing tooobs. If only the Ruskies were making those huge RCA tubes back then, I might still be a Fisher owner. Naah, then I'd probably not have a PS-400. Now back to your regularly scheduled programming....

How do I biamp?

Do I just take the existing crossover out and connect the wires from the woofer and horn to the new one?

What is so wrong with the stock crossover?

So, run the woofer through the Harman/Kardon and buy one or two tube amps and run the horns through those?

Thank you for all of your help.

Welcome grasshopper, to the world of more and more gear.

To Biamp you need an external crossover - they are made by Beringer and other folks - there are even JBL/UREI models. With 2-way Altecs you just need to split the signal into 2 parts - so you just need a 2 way external crossover. You don't use the existing crossover in the speaker cabinet - that, and its controls on the front of your speaker are no longer used.

An external crossover connects to your preamp output to split that low-level signal into a Low frequency band, and a High frequency band (Stereo, of course). For each channel, (Left/Right) you feed the low output to a high power amp, usually solid state. Takes more power to move the big woofer than it does to work the tweeter.
Your newfound tube friends will recommend using a tube amp to feed the horns, but like BMWCCA told me, you can get a nice solid-state amp to run the tweeters. You might even use a pair of Crown Amps - they are pretty good(lots of folks here like them). But I do believe the Altecs are pretty efficient - it doesn't take a lot of power to make them work. You might want to look at Crown amps - say - a D60 or D75 to run the tweeters, and a D150 to run the woofers. Get someone knowledgable to make specific comments - some models of Crown amps are good, some not so recommended.
Someone will tell you what crossover frequency is appropriate for your speakers - I don't know Altecs well enough to venture a guess.

But one final thing to consider.
Quality sound costs money, so any parts you add to your system need to be very high quality as well.
Every device in your signal path is capable of adding noise.
When you have a CD player feeding a receiver, its mostly those two points of possible audio degradation
(assuming your speakers and their passive crossovers are in good shape).
But when you biamp - suddenly, you are adding more devices.
First - that Active Crossover is a major place where noise can be generated.
Some folks here like Beringers, but I've heard other folks here blame them as a real point of noise in a system.
Folks like the JBL/UREI crossovers - but I've folks say they are older tech (80s?) with known design flaws and problems.

Remember that what works for commercial sound reinforcement use may not be what you want to use in your home.
