List of filter capacitors needed for a Mark III cap job

Post by jofipe » Wed Feb 19, 2014 2:52 am

Hi there. I'm gonna send my amp to the tech, but he doesn't use F&T caps (JJ only), so i'm gonna just order them online myself.

So far what i'v gathered I need:
The main filters are 4X220uf/300V. The preamp decoupling caps are 3X30uf/500V.

Anything else?

Thanks!

2X220uf/63v for the EQ supply and 2X80uf/75v for the bias supply.

Tank you very much stokes! I take it that these ones have a rather minor effect on the overall tone?

Yes,but they are electros and are just as old as the power filters,cost is minimal compared to the filters so while you're in there......If you cant find exact values,close is good enough for these,as long as the voltage is the same or higher.Be careful tho,physical size can be an issue,theres not a lot of room where these are located.
