Ampeg BA-115 (HP) schematics?

[Robert M. Martinelli]

Hi,
A friend of mine just brought to me an AMPEG BA-115 (HP) which needs to be fixed, does anyone have the schematics ( or have a clue on where they could be found )? That would make my life a lot easier!
TIA
Best regards
Bob

Here, this is the HP version. Two boards inside, right?

Hi Enzo!
A heart-felt thanks for your lightning-fast reply!
I wish I'll be able to do something in return in the future.
Cheers
Bob

P.S. - yep, two boards ( 1-preamp 2-PS and power ) with a connector between'em

Hi and welcome to the forum!

AFAIK the BA-115HP is a Higher Power ( 200 W ) version of the BA-115 ( 100 W ), so I'd bet the schematics are similar, with the only ( obvious ) difference that the BA-115HP has four MOSFETs in the output stage ( 2x IRFP140 + 2x IRFP9140 ) while the BA-115 probably has only two of them, so chances are you can use the schematic Enzo kindly posted above.

Anyway,
To help keep the forum "cleaner" and well organized, it is advisable to start a new thread rather than "hijacking" an existing one; this way the topics will be easier to retrieve for everyone.

Hope this helps

Best regards

Bob
