I am looking for a little help getting some information on a 1950s (?) Electromuse "Headliner Special" amp that I recently purchased. It is a model A-110, likely manufactured by Valco. Sorry, but I could not figure out how to upload photos of the amp. Here's the tube alignment: 5Y3, 2 x 6AG7, 6J5, 6SJ7. -Does anyone have a schematic for this amp? -Are the tubes listed above the correct tubes for this amp? -What was the original speaker for this amp? I'm trying to tweak this amp, only as needed, to sound better for blues harp. Wondering if the tubes are wrong - and what would be a better speaker than the 8 inch (8 ohm) Cleveland Electronics (#433907) speaker that the previous owner installed. Thanks in advance for any input!
