Up for sale is a rare Eimac X-375 experimental twin tetrode tube.
The tube is 3.5” tall with a diameter of 2.125”. It has good filament continuity and no shorts. I have no set-up to test this tube. Clean glass and pins. Tight base. No loose bits or rattles inside.
Asking $35.00. Being offered AS-IS for display only. Would make a nice addition to a tube collection!
Pick-up in Orinda, Berkeley or CHRS in Alameda
