Ashdown EB 130

[Ted]

Anyone got a schematic for one of these?

There is a schematic for a EB150 power amp here with some photos of the board posted by Baldrick.

I suspect the EB130 and EB 150 are the same with possibly a transformer change or minor issue change.

There seems to be an Electric Blue/Mag manual here which I haven't checked but should have the tubeless pre-amp

Ashdown don't normally release schematics to anyone except people they have approved. They then give you an account that you can log into for schematics. I have applied in the past without any response

the 130 may be the same, just with lower power supply rails for the power amp, anyway, this is all i have, hope it helps

Thanks for that, but this amp has a MOSFET O/P stage with 2SK1058 and 2SJ162s

Ted, you haven't mention what exactly is the problem with the amp. If it is related to the power amp, then similar amps were designed at that time by Trace Elliot, or Marshall. For example this one: http://drtube.com/schematics/marshall/3560pwr.gif
In general the power amp were very simple and usually you can draw the schematics in several minutes (looking at the PC board).
