Folks,
Has anyone compared the sound of the 3B28 xenon rectifier vs. the 866A and 83 mercury types? If so, which do you prefer and why?
TIA,

They are interchangeable in most circuits. I have both, you can borrow them when you get that monster built. 3B28 has a pale purpleish white glow visible only at relatively high current in a dark room.
FG32's are in the truck, remind me tomorrow.

Monster eh, sounds interesting 😀
I remember seeing a post about the 866 having less sag, but i can't find it. More sag will make your amp sound more like a tube amp.
The 866 will also need a few minutes warm up time where as the 3B28 does not.

Nah ... 10-30 secs are enough if you use the tube every day. Warm it 1 hour or more after the first installation before applying any high voltage. If it doesn't light up after a couple of attemps and it keeps on blowing your fuses just forget it, sometime it happens with MV rectifiers.
