Title: Western Electric 422a rectifier in a Torii Jr?
Post by Lance Lloyd on 12/08/20 at 04:09:51

Hello? Has anyone tried one? I’ve read good things but don’t know. I might have a line on a reasonably priced one, but if it’s going to blow the fuse, or whatever other problematic thing, I'll probably pass. The base should fit I think? I have data sheet, but I’m a newbie to tube rolling and electrical theory. I know any rectifier should be able to handle the rush of a 47uf cap, and? 1 amp? Thanks!

Many people consider the WE422A the ultimate 5U4 type tube. It is totally compatible (as long as it is good) and should sound great.

Awesome. Thank you! If I get my mitts on it, I’ll report back. “If it works” is a good point. The guy seems legit, but we’ll see. It’s not a too good to be true deal, but still, really good. The RCA 5U4G that’s in the amp sounds amazing btw. I’m just curious to see what the differences are in a few others. I’ve got a few on the way- a 1960’s Svetlana 5U4G, a Sheldon hi-po 567, and a 40’s RCA JAN 5R4GY CRC(killer deals on all!) , but the 422a wasn’t mentioned as a drop in replacement in the Torii Jr. manual. I really appreciate it!

Merry Christmas and Happy Holiday’s to everyone!
I got the tube. Waited till this morning to put it in and re bias the amp. It most definitely works. Thus far, it lives up to the hype. Liquid, holographic, airy, and remarkably fast, tight, resonant bass. The Torii Jr. already sounded better than any amp I’ve ever had. This improves on that. This tube rolling thing is just icing on the cake.
I hope everyone’s day/week/etc. is enjoyable!
