    Can a Rivera Chubster be rebiased to handle 6L6's without any amp damage? I like the amp, but I think I'd love it with 6L6's and I can't afford a new one right now.

    I believe you can, the pinouts are the same. You WILL have to rebias though. I'm thinking of doing this to my chubster.

    Yes you can. I did it without modification just rebiasing. Much smoother than the stock E34L's. Pop them in,rebias and your good to go! That said JJ6V6's sound even better to my ears in my Chubster! To match the impedance properly using JJ6V6's I switched to a 16 ohm speaker but I dont think thats absolutely necessary. I really digging the amp now after fighting it for a long time! Bob

    Yes and you will need to adjust it to use 6L6's. You will fry the 6L6's in short order if you plug them into the amp biased for EL34's. Bob

    Thanks Bob! I will be putting some 6L6s in there and biasing them asap.

    Let us know how you like them. I much prefer 6L6's and even more so 6V6's over EL34's in this amp. Bob
