Up for sale here is this vintage Precision Electronics S10 tube amplifier, from 1970. It uses 4 tubes, all of which are included and are untested but seem to work fine. It uses 2 EL84/6BQ5 output tubes (one RCA, one Made in Japan and probably Matsushita), one 6CA4 rectifier (RCA I think), and one 6EU7 tube (RCA). I did not replace any of the tubes. This is supposed to have a 6V4 rectifier in it, not a 6CA4, so you may want to replace it. I don’t have any 6V4 tubes or I would have. I brought this up on a Variac, and it plays well and sounds incredible. I believe it is about 10 watts, hence the “S10″ name. It has taps for 4-ohm, 8-ohm, 16-ohm, 25v, and 70v outputs. I took a look underneath and this appears to have been updated with a few new parts at some point–I see what looks like a new cap and a new resistor. This would probably be pretty easy to convert into a guitar amplifier, and I’m sure it would do amazing things. Cosmetic condition is pretty good–this has a little wear here and there, and is missing the round badge from the front unfortunately. Otherwise it looks nice. Please see my pictures for details. If you have any questions, please ask. I have a number of other tube items, collectibles, and vintage electronics listed–feel free to take a look!
