--- Zitat von: Puddnhaid Husting am 22.02.2017 07:50 --- you need about 8A HV and 2.3A for heaters (assuming a GZ34). So a 150mA transformer with 3A filament would be fine

I meant 80mA of course

This online calculator says 140mA:

Maybe I used wrong assumptions :

325v secondary
2x 6v6
4xEcc
Gz34

I get 78mA

Edit: oh I see you used 6600 in the load

sjhusting:
I don't believe 147mA for one second, for the following reasons:

1) with 4 ECCs using max 2mA /triode that would be 130mA for plates and screens for 2 6V6. Take 10 off for screens and you have 120mA or 60mA /6V6. That is believable for 6L6 but not 6V6. I would expect something closer to 40mA for 6V6

2) the Hammond 290CX - recommended for a Princeton Reverb, a 2-6v6, 4-ecc , gz34 amp - is rated at 115mA. Hammond dimensions their PRs very generously.

Jedenfalls ist der Trafo dann ausreichend. :-)


Anfängerfrage:
Im 6G11 werden beide Kanäle über 220k Widerstände zusammengemischt. Was mache ich, wenn ich nur einen Kanal aufbaue, der sich aber exakt genauso verhalten soll, wie im Vorbild? Den 220k drin lassen?
