Peavey cs-400 Blowing Fuse

SAC187

You can use the BTA16-700B, 2N6346, SAC187, or (if you can't find the others- there's always the more expensive NTE part- ) NTE56004.

I'm sure Mouser or most any parts supplier will carry the first or second option..

Hi,
I have that peavey CS-400 for repair. Somebody put power transistor in wrong places.
I downloaded schematics seven times and it was always the same wrong one.
My amp has different power board (actually two instead of one), but transistors were installed according to downloaded schematics. Does anybody know about such a difference? Thanks.

Please post one of the schematics you have (the cleanest and most readable one) and refer to it.
Even if a different version it should match a lot, and you explain what's different.
Good luck.

As I wrote, all shcematics are the same, like one from peavey site and have the different power board. My amp has two boards and power transisitors should
be in different places. Somebody put them the way it would be in the first board layout.
And even different pre-transistors. They should be pnp and npn, but all four are 6344.
So I need the right layout.
Does anybody know anything about that?

All I can think of is, maybe you're in Europe and the European models were different? Try contacting Peavey UK.

Also what is the serial number of your amp and where was it manufactured- does it say "Made In USA" or what?

[Igorl]

It is build in USA, S/N: 4A-01978539. Funny thing is, that somebody put all of power transistors NPN: SJ6357, J6344, D424. I think I can restore the right design, but would like to
see the right schematics.

Peavey CS-400.
This is the one that I have.

Thank you, but this one is exactly like seven I have already.

I would suggest that you contact Peavey and request the correct version for your amp. Be sure to include any date, model, and serial number in your email. It may also help to tell them about the two power amp boards.
