I have several Siemens 6922/E88CC vacuum tubes with Gold Pins for $89 per each tube.
They test very strong with low noise/microphonics for years of trouble-free service.
I can select matching pairs/quads, etc. I will send you photos of selected/matched tubes with actual measurements upon request.
I guarantee excellent performance, so buy with confidence. If you are not satisfied with my tubes for any reason, I will issue full refund for your purchase price.
Payment by check or money order only (no Paypal please). Local pickup is always welcome.
USPS Priority Mail shipping within US with tracking is $9.
