I picked up a Sano 16WR guitar amp yesterday. This amp is something of a rare bird. It's similar to the Ampeg Reverberocket. It's in good overall shape and it works (and sounds good!), but it's due for a refurbishment. The 5Y3GT rectifier tube and socket were removed and replaced by diodes and a 1 ohm resistor by a past owner. The "mustard" capacitor off the reverb pot has a crack in it and the green cap off the tremolo switch pot is oozing wax. This website has a history of the company and some schematics, including the 16WR: http://larryjohnmcnally.com/sano_amps.html. I plan on recapping everything and reinstating the 5Y3, but had a couple of questions for everyone here.
1) Any ideas on who made the output and power transformers? Part numbers are EP-3057 and EP-3036, respectively. Google search brings up nothing and I can't find any manufacturer's marks. I haven't unscrewed them from the chassis yet to check underneath.
2) This is more out of curiosity (I don't plan on keeping them), but does anyone know who made these green molded capacitors? I don't see any brand name, unless the "uf" in the oval is it. The other markings are: MLB/100 uF0.1 400Vcc. F2
Here are a couple more pictures. I will post overall pictures of the amp later.
Tube compliment: 7199 (left top, reverb driver), 2x 12AX7 (left bottom and second from left), 12AU7 (third from left, phase splitter), 7591 x2 (octal sockets), 5Y3GT (used to be where hole in chassis is, behind can cap).
