Hi Mike and welcome to LTG; that might be the best-preserved example of that model anywhere; congratulations! Rather than re-hash what Wally Marx has already written about these amps, read his article
here at Premier Guitar. As indicated in the article, your amp runs on 50L6 power tubes ... if you're in the least tube geeky, a couple of links about the 50L6
here and
here. This amp is low-power ... in the 2-3 watt range. Are there any printed codes on the rim of the speaker? I tried using the codes from the pics but couldn't ID it; maybe somebody else can by eye-balling it. Very cool trem pedal 8)
According to the pics, the amp looks to be completely original electronically which cuts both ways. It's great that it's all original but less so if it doesn't run very well. The amp is full of old electrolytic capacitors that from either years of abuse or dis-use, can dry out and leak DC to ground ... at best a cause weak tone or at worst a source of hum. Also, if it still has a two-prong plug at the end of the power cord, I suggest that even if you don't do anything else to it, you get that cord change; there's a risk of being shocked.
Once past the cord, you'll have to decide whether you want this amp as a 'wall-hanger' ... to take down and enjoy every now and then regardless of it's wheezing and belching or as a daily player that's been updated electronically to the point where you're getting the best the circuit can offer .... wanting to know if love is real so to speak. Anyway, welcome to LTG, good luck, and thanks for sharing the pics of your amp ... it's really in extraordinary condition.
