The small tube amp saga continues! But unless I build one, this will be the last one for a while. But it's a really great one. In my opinion, anyway.
A few years ago I was fortunate enough to have a Supro 1606 - basically the same amp minus tremolo - cross my workbench. I serviced it for a friend's husband. That little amp was just amazing. Great low volume clean tone, and a fantastic blues or rock tone cranked.
Since then I discovered that Valco made a tremolo version of the 1606 - the amp you see here. So I've been on the lookout for one, and I finally got one!
The electronics are identical, and you can see the control panel here. Inputs for 'Normal' and 'Treble,' Volume with on/off switch, Tone, Tremolo speed, tremolo footswitch jack, pilot light, and fuse. Notice the famous "Valco Chicago 51" label. "Chicago 51" was the post office zone that Valco was located in; this was pre-zip code postal service.
Note all the ceramic caps (those orange/brown discs). Ceramic caps were (and are) dirt cheap. They sound rather grainy though - I'm going to swap out the signal caps for PIOs I think. Having said that, the amp is so clean I'm still debating that move.
Ceramics, by the way, are extremely reliable and generally don't go 'leaky' with age the way paper caps do.
As far as I know, no one is making a modern repro version of this covering today. Too bad, because it's pretty unique.
The fact that the silkscreening is so fresh tells me the amp probably wasn't played much.
I'm going to restuff the electrolytic cap can and maybe change some signal caps, but that will be it for this amp.
