Product Reviews
My Transcendent Mini Beast amplifier uses 6 of these power tubes. It's OTL design does not require bias adjustment and tube matching, so when one of the six power tubes failed after a year, I purchased a single to replace it. So far so good. Hopefully it will last longer than the one it replaced. Antique Electronic Supply packed the tube for shipment perfectly. My order was processed and shipped same day. The tube is priced competitively. It's good to have my tunes back!
