Russian 6C33-B

From Russia with love. Need some replacement power tubes for your BAT? We got 'em in stock ready to go. Made in the Ulyanov factory in Russia.

Most amps that use this tube do not require matching, as it is somewhat difficult to match this tube, but we still put each tube through a rigorous screening process and test them on our Amplitrex T1000 tube tester. Most 6C33s you see out there now are used; these are first-quality, brand new still in factory boxes.

Label and box may vary from image above. Price includes matching in any quantity you order, no extra charge.
