AI-assisted summary

Description from the seller

I’m selling a lot of 5 6C33C-B valves/or tubes of original Russian/Soviet production (Ulyanovsk). These are NOS (New Old Stock) specimens, never used and stored with the utmost care. The 6C33C-B are famous for their incredible robustness and low internal impedance, ideal for OTL (Output Transformer Less) amplifiers or high-end Single-Ended.
