    I am a reviewer for the online audio magazine, 6moons.com. I am helping an elderly gentleman get his system going again. His amp requires four of the 6C33C-B tubes. A dealer friend of mine referred me to you. How much would it cost for four matched 6C33C-B tubes? I may need a second matched quad, too, as my dealer friend said he would want some, too. He carries the Tube Guru line of preamps and amps.
    Do you burn them in for any time period? I ask, because the tube has a reputation for fairly high (~25%) reject rate when testing batches (or that is what I have been told).
    Thanks, Steve

    Hi, I like to purchase two dozens of 6C33C tubes (total 24). Need to have them shipped to 20895 zip code in Maryland, USA
    What’s the best price you can offer, and methods of payment?
    I did buy some tubes from you over 12 years ago.

    Kind regards,
