1)with the #26 tube expect around 300Ohm with ll1660 wired 4,25:1
2)intact audio

Where to take the TVC dialogue so to be useful for members looking for? #26 thread? Here is OT, nobody will look for TVC in the PSUs forum.

OK, so i had my SSHV2 up and running on my testbed. Did some modifications to my DC-filter (new choke) and plugged it back. Accidently the output positive twisted wires was loose and i got a short circuit between the positive and negative.
I powered off, and it didn't look like anything was damaged. Except when i powered on i had ~13.5v output, and after maybe 5 sec, the R1 burned.
I don't see any visible damages to any other components, but something must be broken. Maybe any diode? any idea where i should start, or what i first should check?
I'm thinking about putting a 12v input and ground it a the testpoint, just to check the CCS-part first..

That's a good idea to test the CCS first, it shouldn't be left running after the fault. I would test/change Zeners and JFET first.

Did it spark when it shorted loosely by the way?
