I have an Ashdown ABM 200H with a burnt resistor on the power amp PCB.
Any know what value R10 is ?

I have managed to get the occasional schematic out of them without a
password, by emailing technical direct. If you can convince them that you
are a bona fide engineer, rather than just an owner, they might help you
out
as a one-off.

Same as a Trace AH500 I am repairing right now. 220R to both emitters of
BF422, (this one also burnt, reads 880R), collector to 15k to diode to
220R
to +V.
One of my Mosfets is blown.
Ashdown are Trace revisited I believe.

Isn't there a connection between Trace Elliot and Orange ?
** BLT = bacon, lettuce and tomato ??Clive Button was the chief designer at Trace, I think. You often see his
name on the PCB's. You also find the initials B.L.T. on his stuff.
Phil, is there anything like that on the Ashdown PCB?
