 have u rolled any tubes?

Yes

I use Tungsram E88CC (red label, mil/industrial, 1965, 1968 years) and USSR 6N6P (1978 year)

Regal mod (for 6922/6DJ8) applied.

 

Also I modify heater wiring (like "star" topology) with each tube heater wires shielded. All heater shields connected with main star ground bolt.

I use 6H30 which i find to be more dominant(powerful) than the 6DJ8.

Can we have a picture of or heater shielding?:)

(I know it is probably somewhere in this giant thread, but somehow I can not find it.......)

 

which  electrolytic caps are good for using as output caps? Is there a particular brand/model that is noticeably better than the others?

I used standard audio nichicon snap in caps (~$4 each). Or, if you have a large budget, you could use Black Gate 150uf 350V ones (they have them on sale at Parts Connexion for 60 each, down from 180 each) which are good if you don't intend to use anything lower than 250 ohm impedance (lower than that, and you might experience a bit of bass cut off, I think). I personally use 100 uf Obbligato Film and Oil caps, whitch are good for my 600 ohm Beyers.

Hey AudioCats!  Been a long time!

 

To find the discussions in this thread for the output caps, just search for C5.  Certainly lots of options.

The stock one, for reference, is the 470u with a 1u bypass (C6).
