Strange behavior in tube amp... PROBLEM SOLVED!

Hi all...

I am not new to tube amps and such but I have ran into a problem that I need some advise about.

Having two Edcor CZPP50-6k6 output transformers coupled into two pairs of EL34's the voltage exceeds 600V on the plate while the B+ is around 462V. The OPT has a 40% screen tap which gives 460V, but as mentioned the plate is above 600V and my DMM is limited to 600V.

One of the OPT is producing a pretty raw buzz (no speaker or signal) and when I touch the DMM at this OPT plates the buzz somewhat disappears but also there is a spark. Poor connections? Well everything is brand new and have been resoldered a couple of times.

So I need some advise before I go further.

Best regards

Could be the tube sockets perhaps???

Perhaps the pins on an EL34 is a tad smaller than the inside diameter of the tube socket?

Problem solved!

Yeah
