Teisco 78-R

I'll have to assume this amp was an early 70's model, made in Japan.
2 channel bass/guitar tube combo with microphone input and switchable bass/guitar input, volume, bass and treble knobs. The second channel has echo volume knob with pedal switch input, tremolo with depth and speed knobs and pedal switch input; bass, treble and volume knobs also "soft" and "hard" guitar inputs. It also has a stanby switch in the back.
I play mostly blues (slide)and rock stuff and manage a fairly clean sound although somewhat trebly but I figure that could also be due to guitar output. Full volume is not mind-numbing but its enough for my needs at home.

I play an '88 Am. Std. strat with a Seymour Duncan hot stack in the bridge position also a Haganez (Hagstrom III with an Ibanez neck) converted for slide playing, ie. high action and flat wounds. One problem with the amp is significant background hiss also a hum which gains in volume when I use the echo. I strive for mostly a clean sound and usually play through a Rockman X100 (luv that chorus). I get really good tremolo although trem speed is barely audible at low setting. No distortion at high volumes (is that good or bad???).

I figure I could depend on the amp. Although I picked it up for only $10 from a friend, I have since invested about $150 in refurbishing. Main transformer from a Fender amp, filter caps replaced, grounded power input and matched set of output tubes. I figure the output has to be biased by a pro in order to quiet down the background noise. I still want to get an early Fender Musicman or something similar, now THATS an amp.

No customer support available. Us Teisco owners will just have to cling to each other. I wouldn't mind getting a list of the tubes that this amp was originally supposed to have.

I've been playing guitar for around 25 years now. I have a good idea about what makes a good sound in an amp. Basically, I would like to hear JUST GUITAR from an amp and not any hissing or humming that goes along with it. I like the colour of the amp. When I bought it, it was painted black and I didn't even realize it was a Teisco. Someone identified it for me and told me they should be red. I did a little scratching and lo and behold! a nice coral red interlaced with black and silver came to the surface! I stripped it down and took off the black. Now my friend's girl is doing a custom tie dye job for the front (silver face has a big stain on it). Yes, it will look cool. I figure its a keeper just because its an unusual amp. But if I were to lose the amp it would likely take a long, long time to replace it with another. I'll just save up and get my Fender amp.
