I have a lot of pre and power valves that I want to sell and sell with integrity, ergo I need to get them reliably tested. Most are NOS and a few have been used for not many hours. I live in the north of the Tarn, about 30K from the Aveyron. Does anyone live reasonably close that has expertise and good testing equipment?

I have Round Plate 6F8G - Tung Sol/National Union/Ken Rad etc. Russian Melz 1578/ Svetlana KT88/6550/EL34/French Mazda mil spec 12AX7 and more.
