Aguilar schems/help

[drewl]

Any Aguilar schematics floating around or anyone work on these yet?

Seem kinda' new.
I have an AG500, dual channel bass amp. Channel 2 works, channel 1 does not.
No signal in the preamp before it gets to any of the pots, looks like a couple shorted/bad transistors, discrete surface mount transistors/caps/chips in the preamp.

Although not identical, with ch2 working I should be able to figure out which parts are bad and what type of transistors they are, a schem would definitely speed things up or any help if you have worked on one.
Thanks, Andrew.

i was right in my diagnosis and got the amp working fine.
If you run into the same problem let me know and I'll tell you what parts went bad.

Look for two SOT23 surface mount 2N2907's in the channel 1 preamp section,(standard PNP 3 pin transistors) that's what went bad in the one I repaired last year.

That's all I wrote down about it, don't even remember it but it must have been pretty easy to figure out
or I would have documented more.

Hope that helps.
