Hi All
i recently rebuilt this amp for my son as main caps were swollen ect - it now works great and looks in my opinion very much like the Earthquake early 90's pa2300 models - anyone know what amp this actually is ? or any detail - the heatsink has no markings at all.
i presumed its one of the clones of the various 2300 - but im happy to be wrong - anyone else come across this board before ?
i set the bias at 50ma : anyone able to confirm this would be correct ?
many thanks

Hi perry
Thanks for responding - the tag I put on - it says refurbished and the date ... as I tend to forget when I do these things....
I have a matching amp that I’m almost finished for him - approx 1/2 the power . (Psu has 2 caps) But again no detail on the board or heatsink.
Cheers
Tony
