circuits and data - Quad IIequivalent transistors...

below is a list of equivalent transistors for use in early solid state Quad equipment - particularly the 33 and 303 (Many thanks to Michael Coatham for sending me the data)...


U17219 ~ BC546B
U17229 ~ BC556B
38495 ~ BC441
38496 ~ BC461
38494 ~ 2N3055
40409 ~ BC441
40411 ~ 16012 ~ MJ802
BC154 ~ BC214


the above is by no means a definitive list, and I'm afraid I can't take responsibility for any possible inaccuracies. Please do email Quad World if you can add anything...
