It's a 2-amp fullwave tungar. btw, the tradename is rectigon not recticon. Some folks use them as tube rectifiers for a filament supply or a supply for field-coil horn drivers. -Ed .......

I've build an amp using AC on the 300bs and with hum pots, and cathode bias. I was able to get it down to about 2-3mv of hum measured at the speaker output terminals. This was pretty acceptable, but I .......

My POV is that even within the sphere of WE, the 91A is overhyped and not all its cracked up to be. If you have mega$ and want to live large in the WE world, there are much better choices from the POV .......

The other 2 besides the RK-63 are likely rectifiers, specifically probably thyratrons or Tungars designed for pulse usage I'd speculate. RK-63 is a cool one, no doubt. -Ed .......

Almost certainly it's a euro rectifier rebased to an octal base. Something like a Tele RGN 2504 or something like that. -Ed .......

hi Kevin - Yes, that's what I meant (higher current), e.g. say for a 6A filament tube. (e.g. 75TL/TH). Good to know current-sharing won't be a big issue! ;-) Thanks, best regards -Ed .......

Would it be possible to series/parallel this for higher-current applications? Or is that not even feasible? THis is just an off the cuff question, I haven't really thought it through yet... (e.g. how .......

I am convinced now that it's taylor, no question. Spacing looks like 211/845 spacing, so it's not a 203 or 805 or 838 or something wacky I'd think. The base is all wrong though. it must be a euro-base .......

I'll trade RCA 845s for WE 300As. Feel free to email, since you don't accept email I can't email you. indeed, WE300A is a nice tube for an amp project. However I'd use something else in the meantime .......
