I have around 100 Tubes 6C33C-B Brand New Brand SOVTEK tested one by one, that I purchased in Russia in a local dealer.
The tubes have their Original Box, and are 100% working. NEVER USED.
For Tube Amplifier like BAT, LAMM, Einstein, etc, that use this kind of tube.
I attached some pictures for check the quality.
I'm asking only $15,00 for each tube a true bargain when compared with the retail price ($59,95).
I'm located in Europe (Portugal) postal Code 2410-096, and I will ship worldwide by DHL.
I accept credit card, Bank Wire Transfer and Paypal (add 3,8%).
Thanks for looking.
