It is of a little newer design, uses a better crossover, a 931-12 Mantaray CD horn with a 902 HF driver.

Thank you for taking the time to explain how this works, and for the links. You have been very helpful.

I did have a couple drivers that required over 20 nickels, so I need to find another way,...

I will study the info from your link, and use it the next time I play with one of my drivers. I will turn down the drive level as 94 dB (Altec model 14) is the lowest sensitivity speaker I have...

Zilch - Yes, they have a fairly concise description of the word heuristics as it applies to various areas of interest (not so much on DIY speaker building???).

How about measuring the volume...

remusr - Have you ever had weak Alnico magnets recharged, and did it bring the sensitivity back to spec? This kinda changes the "old" perception that Alnico is always better, and ferrite magnets are...

remusr - Are you talking about the Alnico magnet being partially demagnitezed? You don't see this kind of sensitivity difference with a ceramic / ferrite magnet? It's good to know that most...

Now that several of us have the "Woofer Tester II", I'm wondering what opinions people now have. Is it too good to be true or worthless?

I tested my Altec 416-8b's, my 2226 J's, and Altec...

Just got the email that it has shipped! I hope it's not a cruel joke:(

Gary,

Well, you would think that 14 should come before 15, but...If you search the Altec catalogs, on this site, you will find the Model 15 in the 1976 "home" catalog, along with the 17, and the...

For what it's worth, my Altec Model 14 speakers (which are later models than the Model 15) have almost identical woofers. The stamp on the cone is "18-83-034642-01" and the frame measures 13 3/8"...

Ken,

Are they using plated thru holes? Most double sided boards would use plated thru holes to ensure there is a good connection on the component side (where you can't see it). Drilling out the...

I always liked the McKenzie Brothers, and the last time I saw them was in a beer commercial, eh? They dived out the door of an airplane after a beer bottle, (that rolled out the door). I may have...

Yes, Thank you Widget! I'm around enough control freaks already! I don't need some wise ass popping in and out of these posts, just to cause trouble. IF all the evidence hadn't been deleted, maybe...

Yep, all it takes is a tube manual (or diagram from the web) to get the socket pin-out, then carefully draw the connections and components on a sheet of paper. You could even post a picture of your...

I was just wondering if you got it, and were able to check it out?

Richard C.

Even if this "chassis" has 6Y6's which could be used for a single ended audio amp, I think there would be better tubes to start a single ended project.

I like push-pull output like 6V6's (Class...

ART DTI - Parts Express 245-875 for $45.00! MCM 555-7685 same price.


Has anyone installed one of these to eliminate ground loop "hum" problems?

I just couldn't stand the constant 60Hz hum...

Maybe, If you needed the parts??? - No I don't think so. $138 + S&H! It's not tested, and both power transformers could be burnt copper & iron.

I did send the ebay seller a message telling him it...

I sent a note to the ebay seller telling him it was a power supply. The guy that buys that will be in for a surprise!:banghead:


A field coil power supply could / would be built with about 1/4...

The reason Atlanta had panic gas buying on Wednesday, is that we were warned that most of our gas stations would run out of gas, and get NO more for awhile. Two major pipelines that supply Atlanta...

I think someone is laughing at "all" the people that know what a Yenco Chevelle is worth. What kind of a wife wouldn't know what she had in the garage??? Most "husbands" wouldn't want anybody...

I looked up the term "modulated DC" and it seems to pertain to pulse width modulation and/or switch mode power supplies. Probably would pertain more to Class D power amps. I would say if you look at...

That is funny, BUT it is hard to prove to someone who doesn't have a clue what he is talking about. These idiots could obviously use a "basic DC theory" course, and then a "basic AC theory" course,...

Yes, Happy Birthday. I really have enjoyed reading your posts; 1st on the Altec hostboard and now here! I have learned a lot. You seem to have an ongoing search for replacement equipment - that has...

Widget,

I still have a pair of EV T35's, and a pair of EV 1824M's that I bought there. Magee Radio used to sell large console radios from the 30's? thru the early 50's or so, and then they got...
