Got a couple new amps on trades and a local second hand shop. First one is an old (late 50s?) Silvertone amp and speaker for a record player (I assume ). Has an RCA input, 8 ohm 8 inch speaker and volume, treble and bass controls. 6v6 power tubes. Can't remember the preamp. Complete schematic drawn on the inside. My idea for this one is to swap the RCA for a 1/4" input and add an external speaker out. Would like to add a 3 prong plug as well. Most likely will have an amp tech look it over. Second is a Traynor YGM-4. 4x8 speakers, reverb (not working) and trem. This one seems a bit quiet at half volume. Not sure what's going on but seems like it should be louder. Needs a 3 prong too I think. Interesting amp. Again probably heading to the amp tech.
