When fuses blow???
--------------------------------------------------------------------------------
I have an old JMP Marshall head,,MK2 master..
The 1amp H.T. fuse, which I see is tied to a cap can, keeps blowing as soon as I turn it on... I looked over things very well looking for a short, but see nothing.. Is there something obvious I should check, that I may not see visually?? I'm going to check to see if it does it with the tubes out next..
Thanks,,,

I suspect shorted power supply diodes.
