Hi all, I was wondering if someone could give me some advice.

I have a Marshall 5210 that keeps burning R60 on this diagram - http://www.drtube.com/schematics/marshall/5210-iss3.gif - It's the one right at the bottom of the schematic on the D bus.

I have swapped out C47 & C27 but notice that there is no resistance across the mounting holes for C47 with the capacitor removed - would this be normal?

Having a quick poke with the multimeter (with a face full of smoke) showed 26v at the R60.

Any help would be fantastic, Thanks for reading.

Joe

Edit: I've just removed ZD3 and found no resistance across it. New one on order. What can do this?

Cheers, J.
