I haven't biased my RM100 combo in a while. I got a new pair of kt66's and went to install/bias them and I think my amp has a problem.
First, one of the lights came on saying i had a tube failure. First I swapped positions of the KT66's and had the same result. Then I tried EL34's and 6l6's in the same spot and got the same result. I also couldn't get a reading on my multimeter. The tube failure light seems to go on no matter what tube I have in there.
Problem 2 is when I went to check the bias on the two tubes I've been using (i've been running the amp at 50 watts) I couldn't get a reading from one of the test points.
The fuses seem to be fine.
What's going on with my amp?
