Default Toshiba 2sb755 and 2sd845

Any body know of any good ones, Or where to find matched pairs. Or even better a suitable replacement.

If I cant build it or fix it I really dont want it.

I have two pairs of these transistors and I pulled them from an SEA series JVC Component Stereo Receiver that dated back to the 70's/80's I believe.

I'm very curious how to work these things, I saved all of the power supply guts...

(transformers, jug size super capacitors, diodes etc.) (I gutted the board because I fried the pre-amp drivers and the electrolytics across the entire board were dead)

......and am hoping to build these up with a pre-amp. You said you are interested in finding a pair or two sets? I have some but they are not in great condition, a lead has broken off of one of the 845's.

If need be, contact me via E-Mail @
Would love to hear from you!

Default Is there any hope for humanity...

Is there any DIY or basic schematics or parts lists for trying to make an amplifier?

I happen to have a CompSym. pair of Toshiba 2SC5200/2SA1943 transistors. I'm really clueless when it comes to alternating current and non reactive devices.
