Haha we all lose our minds sometimes. I bought the Western Electric 420A and don't know why I bought it.

Some times you can't pass it up might never see these again.
Shure do hope they are not noisy so I can rebuild my preamp and use them.

The consolation is that you have authentic Telefunken boxes.

WE420 to ECC83 to 6SN7. Merry Christmas!

and I might consider the Verite Close though I have resisted it much. If not for your persistence...... I'm almost convinced.

Resistance is only delaying the inevitable. We both know it.

Can I get your opinion on sound,price and authenticity of this rectifier?

It appears to be authentic. It is a G2504 manufactured by Valvo in Hamburg in the early 1940's in support of the war effort. However, with the end of the war, the Hamburg plant was shut down and all production was terminated. Shortly thereafter, Philips regained control of this facility, but it appears that they chose not to resume the manufacture of this rectifier.

Compared to similar Telefunken rectifiers, the Valvo has a bit less upper midrange and treble emphasis, but I would still call it bright. These 2504-type rectifiers can provide at most 180ma and are not suitable for use in the GOTL with 6AS7 and equivalents. That said, they are absolutely fine in the GEL3N, and I often use them with four 6BX7 in the GOTL.

Well I lost my mind and bought these. Not even sure what I am going to use them in.
I hold @LordGwyn personally responsible.

Just ordered these nice sockets for them

Ahh,one of those rectifiers that can only be used w/ 4 6bx7s...I will forget and blow up a city block. Im gonna pass. Thanks Ken.

The 4004-types, like the Telefunken RGN4004, Valvo G4004, Klangfilm 77305, Philips AZ50 and Philips 1817 can provide 300ma, which means they are suitable for use in the GOTL with any and all output tubes. However, some of these tend to be expensive....

Screw the neighborhood power grid! Unfortunately, you're more likely to damage your GOTL...

There not Yamamoto better made in Korea use this brand on my 300B amps.
Could also use this socket for four volt rectifiers they have one with just 4 pins too
