Definitely yesterday was very very tired, I'm sorry for misunderstanding about TVC gain but I know there is some TVC with gain....
Quote from Dave about TVC
"Yes, some people report good results but be aware that wiring for 6dB of gain means that the source will see only 1/4 the inductance of the full winding. Stacking the core with more interleave will recover the lost inductance, though the ultimate success may depend on your system and your requirements."

Felipe,
do you need that extra gain? Also don' t forget that output impedance will go up with 6dB gain.

George,
Do you know the output impedance setting to 6dB gain?
Have you played with different inductance in yours TVC?

1)it depends on the output impedance of the stage before the TVC. How much lower, better ask Thomas Mayer who is an expert on this.
2)no, as I couldn' t find a reason to increase the inductance.

1/are the Lundhals
2/I assume you don't need more gain or inductance, how do you know if you need or don't need more inductance?

If you got two B+ local points to feed for two tubes, link them and put F+,S+ as a midway node for example.
Salas...I have closed circuit at the branch point, and made connections to the 2 tube with equal lengths (14 inches) wires....work out perfect....thankyou.
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.
Thanks alot Salas, have to do that tomorrow then, probably not that hard to fix - but it is always good to have any idea where to start!
