Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Re: Favourite 12b4 Brands?

It's funny - just about every post I read on 12B4s refers to microphonics and inconsistency between samples. I have regular GE, JAN GE, RCA, Westinghouse and Mullard (rebadged RCA I think)in my stash and have yet to experience any microphonics related issues.

Moreover, I recently tested a batch of JAN GE and found them all to read within 5% !

Maybe I am just very lucky?
