None, its Cable ties. But heat glue works fine

Hi Staffan, comes out nicely on the box. Did you get any difference in tone with the DC in the filaments nonetheless?

DC worked fine and I didnt hear much of a difference so far. Gonna work off B+ ripple tomorrow and then compare to elevated AC.

But overall its a lovely little rat-amp. I will try it on a friends 6C33 OTL some day, which is especially hard driven.

Hi all,

I've just built 6V6 pre for my friend. Here are some pics. Sound is very good on mid, bass and rich tone.

My schema is based on Salas' one, but I use AC filament with hang of 40Vdc. PSU is with 5V4 tube, CLCRCLC for separate chanel. No hum AC, but I have some hizz on one chanel. I think it's tube noise.

Good looks. Did you take any anti microphonic measures? Its the common cathode 15dB gain circuit yes?

R Cruz, I assume that you have built this, having listened to the NJfet RIAA.

No.... unfortunately I do not build anything with bulbs for long now... but I will.

I am using a p2p dcb1 with V12r shunts as a reference.
