Default TO220 and TO247

Hi!
Could somebody to suggest me a good and NOT in TO3 case transistor substitute instead of the MJ15003? For my design the TO220 or the TO247 would be better.
Thanks!

Tyimo

Default Not TO3 Transistor

Well there is always the TIP3055, as long as you don't burn too much power with it.

No, I have not tried it before, so no guarantee of quality of sound. But I imagine it should not be too different from the original 2N3055.

Thanks!
I would try the 2SC5200 or 2SC3281, if there is not any stability problem. Is there?

Can I build this amp from using only the schematic on page 11 fig 3 The high power circuit? And if so what are the values of r14, r16,r15,r13,.
Thanks. Steve

Hi Steve,

Fig 3 – The Higher Power Circuit

100m = 0R1

I used 4 x ohmite 25W 0R1 power resistors for the current amps and 4 x Caddocks for the older amps. Can not tell the difference bewteen the two brands

Regards,
Chris
