Phono preamp-modules

[hjames]

That gold "adapter" scares me! It looks like party paraphenalia from the 60s ...
or some kind of weird gear from Johnny Neumonic - or underwater breathing adapter for James Bond - or ...

Thing is, it would probably work, but I don't even want to know what it does to the impedance of the circuits ...
he he he

... anyway...

Seawolf, this is the part I mentioned from PE:

Now now, what are we dreaming about, Hmmm?? I'd say more of a 70's design. Or are those dual quads? Some of us (most ) here remember carburetors, right? Frankly, I don't miss them.

Actually, I prefer Y cables, those adaptors are a bit tight clearance wise when making connections. Of course the paralleled impedance will be lower than usual, but how low depends on the sources. At less than 10k Ohms, bass can start to roll off but nothing gets damaged.

So let's see, you need a phono preamp, and Seawolf wants to bypass his, are we ever satisfied with what we have?? Tsk tsk...

Hi, Heather,

A fairly inexpensive option is a pair of (yellow) Altec 1579 modules. For your app would require minor DIY, a pair of octal sockets, a small project box, and a wall wort PS. They show on eBay fairly regular, usually bring ~$25-30 each. Simple project, pleasing results, but likely would get you booted from any hi-ender circles (which suits me just fine ). I'll dig some out and post specs if you want.

I'm in the process of building a phono preamp with the 1579s, but with a custom power supply of high quality. Does anyone have any experience with these modules and would like to add anything?

I'm using a 12V toroidal tranny, a cascade of MUIR diodes and fairly beefy caps.

Anyway...

Our friends at PE have an inexpensive phono-pre that may be good, made by ART for $49, check it out:

Found a version of this at a music store today for $16 on closeout.
