Following the restoration of my Taylor 45C and calibrating the grid volt pointer at 0V with a scope I sent three valves to sven swe.
He did a very professional Gm comparison on his two Taylor 45Cs and an AVO.
I'm delighted to say the results were very close and I now know that my Taylor is good to use.
I hope that sven swe will post his results with commentary.
I will be pleased to send the same valves to any other user of the Taylor 45C or for that matter a user of any type of valve tester.
Thanks Sven.
