Does this amp need to be biased if I replace the tubes? This is a Orange TH30 amp...

I believe it is cathode biased which means there is no bias adjustment needed.Legend wrote:Does this amp need to be biased if I replace the tubes? This is a Orange TH30 amp...

That is so. Doesn't mean that ALL valves will be run in the correct range, but all with fairly normal current ratings will.
Thing to do is just to specify which amp they are for when ordering valves from a good supplier and they should supply suitable ones. Then you don't need to worry about a bias check.
