Hi Folks,

After years of wondering what happened to that cute little amp
of my youth, I found it in with my Lionel train stuff while cleaning
the garage. The newspaper it was wrapped in is from 1993, so I
know when I saw it last. Anyway, its a little PP 6V6 amp with a
12AX7 and rectifier tube (didn't pull to get number). The filter
cap is a Magnavox 450V, 30uf, 15uf, and couple of more sections.

My question is this: to reform the cap, should I pull out all
but the rectifier tube? I have a 10A variac I can use. Assuming
it has a fuse (don't think it does), and it holds, and no smoking,
how fast should I bring up the voltage? Given that the tube
won't conduct until the heater gets pretty warm, can I start
1/2 way to 120Vac input? Would it make sense to sub in SS diodes
during the process and bring it up more slowly?

Beyond that, the rest of the caps look like they could use
replacing. What decisions are to be made about the value of
restoring this thing?

BTW, its marked as an "AMP135AA". Neither Yahoo nor Google
find any reference for it.

Thx, Chris
