Oliver, there is only one Zobel cap...
PS. Do you recognize your board?
Sure i do
Looks cool with the red JENTZEN caps.I still have the Mundorf M-Caps on my personal boards. Perhaps i try a M-Cap supreme....
BTW, i've got some 1K0 bulk-foil trimmer from Texas Components. Let's see if it perform better as the standard...
Yes, that's the one linked from post #1 as the evolved one. Some use clamping diodes on the gates as I have shown also, some don't, but there is no appreciable failure rate reported here with either.
Now the 1260W 1K0 Bulk Metal Foil Trimmer ($29.29 from Texas Components) is installed.
Very interesting... The bass goes deeper and is more precise than with the standard trimmer.
For source information about the Bulk Metal Foil Trimmers, look into my Blog.
Additionally the 1µF of the Zobel is bypassed with a 0,047µF/500V russain K72P-6 teflon cap.
I have also changed the heatsinks to a bigger one, to have a bit more "Air" for shunting
The result astonishes me! I think that´s the last tweak on my SSHV modules.
Now it´s really time to design the case for the whole DAC.
An externally hosted image should be here but it was not working when we last tested it.

My trimmer is a +-5% tol. one.
Also a possibility, but i want to be flexible for different tubes and
to check different tube rectifier!
That's a good idea if regulator it's only for an application, fixed resistor can give exact value as a trimmer except if you buy a "on request value" naked Vishay....
Jeez, Joshua, where did you get that from - 1uF/600V is a standard value and readily available on fleabay.
The Obbligatos are a okay too, but physically big and that metal case can be a pain.
The Jantzen's are more "toppy" but still rather okay in comparison to the inexpensive little ol' "Audiophilers" - IMO, I might add!
... my 2 cents.

Perhaps i go with 1µF Mundorf Supreme...and bypassed with 0,1µF Duelund VSF DC Copper
Try Mills, Welwyn or Vishay/SFernice (vitreous enameled) & let us know?

I use Auricap bypassed with FT-3.
