Air Tight 300B/WE rectifier question


Guys, need some advice. I know I should go to AXISS, the distributor for this amp, but thought I'd check here first. I run an Air Tight 300ATM 8W SET amp, with WE reisuue 300Bs, Chelmer CV491s (12AU7 drop ins), RCA red letter, grey long plate 12BH7s & a quite nice National Union 5U4 rectifier. Mpingo discs on the transformer casings and an Electrglide Fat Boy PC.

Itching to do something...I would love to grab a WE 274B off of ebay sometime, but not sure its an appropriate drop in for the 5U4 in the Air Tight (and think it might take a couple of years to get and answer back from Japan...)

I know a 274A or B is not a universal drop in for the 5U4, but would like some advice on what to look for to find out, assuming someone doesn't know off hand.

Thanks, Asa

Thanks, Al. Good stuff. Thank you for your efforts. It sounds like not enough current in the 274B for my application. I had that feeling, but REALLY wanted someone who knew to tell me, hey, go right ahead. Apart from going for an original matched pr. WE300Bs at $2-2.5K per crack, I've sort of maxed this amp out.

Any other comments are, of course, humbly appreciated...
