813 CV26 stc western electric mint boxed pair tubes
813 CV26 STC Western Electric MINT boxed pair tubes
Here we have a rare pair of 813 beam tetrodes CV26 KB/F on glass. Rated among the best sounding musical valves ever made and ever preferred to 845. These were made by STC Standard Telephones & Cables LTD. which as many of you know distributed many globe tubes by Western Electric so STC was the European distributor. Both have been taken out of their strong boxes and tested for filament continuity which is perfect with full emission. These valves are fed at 10 Volts filament with anode supply voltage of up 2,000 Volts!
The classic envelope is 60 mm diameter and 170 mm long excludin base pins. Anode is 53 mm long and 48 mm wide. They will be well packed. Thanks for watching.
