Hello. I recently came into a very beat Supro 6L6, 2x10 combo with trem. The codes date it to '63, so I think it's a 1690T (the faceplate is so oxidized, you can hardly make anything out). I'm guessing it puts out maybe 18W on a good day, but I can't find any specific info. Any info about output power is appreciated. Thanks in advance!

I'm in full ressurection mode today after putting in a lot of work on this schematic. I sincerely hope that it will be helpful to what seems like a lot of requests web-wide for information on these things!
