I replaced all the big capacitors of my 1959RR because I thought that the noise is coming from them. (i know I am a newbie with tube amp repair). I retubed it as well with EL34EH and biased it to 33mA +/- per tube. Anyway, all was good until I plugged in my THD attenuator and both volumes of the 1959RR at 8. The amp sounded so good with the Hendrix cabinet then I saw two tubes lighting so bright and caput goes my amp.
I was so worried that I baked the transformer and the PCB as I saw in another post in the internet. I plugged the amp again but no light coming from it when I switched it on. So logically, I thought of the wall power if there was electricity and there was. So the next thing that I checked was the power cable. I tried another power cable and it worked. Good thing that the power cable that I am using has a fuse.
So i fired up the amp and it was working.
When I connected the bias probe, the reading was the same at 33mA. I started playing and put the volume to 4 and the bias reading came up to 70mA. I don't know if this is normal. Further on I put the volume up and the bias became higher again. Is this normal for a non master volume amp?
