Fryette Two Ninety Two Power Amp Retube Kits

The Fryette Two Ninety Two Power Amp. The kits we offer here are the most distinctive in tonal character, forged from many years of research. Every kit is configured to provide a specific sound/experience.

The bias pots are accessed from the top of the amp. We use bias probes to test and set the bias on these amps. You can bias one tube on one side and then one tube on the other side. All you need to check and adjust the bias is a bias probe and a Multimeter, or our all-in-one Eurotubes “Pro One” bias probe that reads both the plate current and the plate voltage simultaneously.

The default power tubes for all of our Fryette Two Ninety Two kits are the JJ KT88’s. The JJ KT88’s are extremely thick and rich sounding, they are a very high power tube with lots of headroom, thunderous lows, thick/aggressive mids, and sweet detailed highs. You can use the dropdown to select the JJ 6550’s. The JJ 6550’s are very warm with a great clean tone and the breakup is raw, crunchy, and gritty. If you want an Angus – AC/DC type tone then these tubes really deliver! They are simply a lot of fun to play. The JJ 6550 will not make quite as much power as the JJ KT88 and the KT88 is a bit thicker sounding.

The Standard Retube Kit is as close to OEM as possible. Maintaining the amps stock level of headroom and gain while providing a warm but even handed overall sound. The kit includes one matched quad of JJ KT88’s by default, two Matched and Balanced JJ ECC83S’s for the phase inverters (V1 – V3, replacing the 12AX7’s), and two Matched and Balanced JJ ECC82’s for V2 – V4 replacing the 12AU7’s.

The Gold Pin Retube Kit uses the JJ ECC83S Gold Pin variants to provide a smoother, creamier, and more singing overall sound. This option is less aggressive and has less “teeth” when driven hard. If you like a classic raunchy gritty overdriven tone, we recommend looking to the Standard or High Gain option. If sweet, open, and more refined is what you’re after this kit will do it. The kit includes one matched quad of JJ KT88’s by default, two Matched and Balanced Gold Pin JJ ECC83S’s for the phase inverters (V1 – V3, replacing the 12AX7’s), and two Matched and Balanced Gold Pin JJ ECC82’s for V2 – V4 replacing the 12AU7’s.
