Comment on Changing Tubes on Vacuum Tube Amplifiers : How to Set Bias for Right Power Tube of Amplifier by ectskater

Thanks for posting this info.
I have a Hughes and Kettner tube 50 head that I am replacing all of the tubes in it.
It has (2) EL34’s for the output, and (3) 12ax7, the head has reverb, so I imagine one of the tubes is a driver for that signal path.
In any case, I would like to know if you have any tips on doing the bias to it, I can’t find any info on the spec for it from H&K, so I am hoping if it can’t be biased,(fixed?), that the tubes will be OK.
God Bless- Joshua

how many times you turn your amp on and it you give the tubes enough time to warm up plays the biggest roll in my opinion

Firstly that didn’t make sense, You’d have to be an idiot to be not able to line up the pins on the bottom of the tube with the socket itself…

Your retardedddddddddddddd tubes last so long depending on how old they are. my buddys got a high watt from the 60’s with original tubes. hes taken them out and put them on his tube tester and they still score “good”

It sounds like you got 2 overlapping distortions thats not in sync. Very undesirable!
