2SB552 & 2SD552 Applications

Ciao e tutti!

Genuine Toshi. 2SB552 & 2SD552 complimentary

I used to use these devices extensively consequently I have a large number of them lazily sitting round on heatsinks & in packs just gathering dust.

Anybody know of a really nice power-amp that I could build to use them up? :idea:

The devices I have are mounted on large heatsinks. There is 15 of each per heatsink used to drive 3 motors swinginging them between +/- 40VDC from a 20A supply.

The file seems to be too big to upload so here is a link to the circuit: http://snipurl.com/b80pr

I don't know how well the circuit would work as an audio amp. Needs abit of d.c. protection :cheerful:
