Valve Faults

Have you ever wondered why amplifier valves wear out or why they dont last as long as solid state stuff? Why do the big amp manufacturers give you three years warranty on the amp and 90 days on the guitar amp valves? Valves are very old technology.  The popular 6L6 output valve came to market in 1937 and our little friend the 12AX7 ( ECC83) was first introduced by RCA way back in 1947. The

Upgraded JJ EL34 Valve kits

We have now upgraded all our JJ EL34 valve kits.  Our kits now include the JJ EL34 II. The reason?

1964 Vox AC30/6 Service

By the way, the “C” is the Russian letter for “S” so it is the logo for the brand using the company name first letter. Here is a cut and paste from a well known valve reseller

Silent Fender Hot Rod Deluxe Fixed

Another Fender Hot Rod Deluxe arrived .  This was one of the early ones in really nice physical condition dating from around 1998.   It was made in the USA.  Alas, I only ever see sick ones.  This one had about 0.2 watts out on full volume and totally distorted. The valves had not been changed in years and the output valves were original Sovtek 5881’s rebranded as Groove tubes.  They were still kind of working
