JMI AC10 Mod

[Travis]

Hi!

I wanna add more trebble to a JMI AC10.

Someone know where is the schematic of this amp?


Thanks you all !!!

I think it´s similar to original ac10, some recommendation about cap changue?

Is it a 4 input AC10? If so, I think this is the schematic to reference:



Are you trying to brighten up both channels or just the Normal channel?

I will take a look!

Thanks

The normal channel

I think adjusting the coupling caps C4 and C12 down from .022uf would be your best bet. Perhaps start with .01uf and drop from there.. Some Marshall preamps use .0047uf, so that's an option too.
