I have several Siemens 6922/E88CC vacuum tubes with Gold Pins for $89 per each tube.
These are labeled as Telefunken, but these are definitely Siemens tubes and have NO Diamond on bottom. They have typical Siemens code etched on glass such as "Aø 1≠ 5C". They are made in 1964 or 1965.
They test very strong like NOS for years of trouble-free service.
These are PHONO GRADE (low noise/microphonics) and suitable for all applications including Phono Stage/Line Stage and, of course, Driver Stage.
I can easily 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 $8 flat.
I have over 400 100% positive feedback on Audiogon with the same member ID - "sojs", so buy with confidence.
