Re: Symptom(s) for a fading 8877 tube?

Thanks very much, Adrian !
I have one of those new-fangled SS amps - a 2.5kW PEP out unit from Onder at VK-AMPS. Very nice on CW and SSB, but it doesn¡¯t have the ability to run decent power out on digital modes, so I stick with my DX-2SP for that.
Perhaps I need to by a couple more and combine the output, broadcast style !
Cheers and thanks again,

Thanks gents - the below was awesome. If you have any other scientific papers/references on tubes, please post the links.
Many thanks.

Glad to help with the post John. Tube amps are a dying breed in VK, with solid state taking over, as pricing and devices improve.
It is good to save all the tube amp info one can find.
