Yes, More PEPCO

Well, the Paul amp seems to be behaving so far: no blown tubes or smouldering resistors. It does have a strange habit of going dead silent (instead of the usual faint hiss of a live amp) after about 10 seconds if there's no signal. As soon as a note is played or the patch cord touched, it springs back to life. This isn't normal behaviour, so I'll have to do some more probing.

I also plan to tune up the Pine amp this weekend with new parts, as well as start work on my "amp from parts" project. Here's a few pics of the Pine:


This is the cabinet, with the groovy mac-tack covering and "white noise" grill cloth. Not sure if the handle is original. Looks a little odd.

The chassis, showing (from left to right) sockets for the 5Y3GT rectifier, 6V6 power tube, 12AX7 tremolo circuit, and 2 6AV6 pre-amp tubes. Note the empty socket hole, as the same chassis was used by PEPCO for a number of different configurations.

And finally, the control panel for the amp. Four inputs: enough for the whole band!

Hey! I just picked up a "Paul" 201 model amp on Ebay and am very impressed with the sound--blows my Blues Junior away. Mine looks very similar (same handle, by the way, so I think it is original), but it doesn't have tremolo.

Does yours have noise issues? Mine hums quite a bit.
