Need help on a old circuit - early Lafayette amp

[solidjackson]

I'm not sure where exactly to put a topic like this, but this forum seems the closest to what I'm asking.


You may have seen this on the tube forum a couple of months ago. It's a "Auburn Amplifier" made by Wholesale Radio Supply. I researched the brand name and found that this company was the forerunner of Lafayette Electronics, but couldn't find a schematic in any books.

I eventually decided to draw a schematic.

It's probably pretty inaccurate, because I've never drawn one before. The transformer was pretty tricky because there were about 18 solder taps on the bottom (it's got a Victor logo on it, which is kind of cool). I hope you guys can read this.



I've replaced all the old electrolytics, but I'm left with about 3 wax-paper capacitors like the one in the middle of the picture. These don't have any value on them, but they have numbers like "85397", or "5957" printed on them. Does anyone have any idea what these are? Also, what size coil will I need to put in to replace the speaker's field coil? I wouldn't mind hunting down a field coil speaker, but it seems if most of them are proprietary to manufacturer.
