I need to thin the herd. I've used all these rectifiers in my UFOs, some for a few days, others for a few weeks. All sound good and test strong and all are from the golden age of tube technology so should be good for years of trouble free service in any Decware amp that uses 5U4G tubes. Most sold as pairs, at these prices you should buy 2 even if you only need 1. As Steve said in his latest 300B amp post:

Quote:


Octal (Normal socket) Rectifiers.

2 RCA 5V4G  $45 for the pair.
(5V4 is the US designation of the GZ32 and is indirectly heated so it soft starts the amp.)

2 Ken-Rad 5V4G $45 for the pair.

2 Sylvania 5V4G $45 for the pair.


4 Pin Rectifiers.  They need an adapter you can get e.g. here:

or

the tube pins are size coded and only fit one way, it is simple.

2 National Union 5Z3 (5U4G equivalent), JAN (Joint Army Navy) rated. $45 for the pair

2 RCA 83V (5V4G aka GZ32 equivalent). $45 for the pair

1 National Union 5Z3 $25

1 Raytheon 5Z3 $25


Most tubes in generic boxes. Prices include paypal and USPS priority shipping to CONUS.

PM with questions.

Thanks!
