For Sale: (7) 833A tubes.
These tubes are in perfect condition and tested. They are Chinese but of high quality. The test data is written on the glass as tested recently by a friend. These were never subjected to any kind of duty cycle. The transmitter they were intended for never made power as it was a project that was never finished, therefore these tubes were purchased new from ARS and were likely brought up with filament voltage only. Two of these are solid graphite plate construction while the others are ribbed plate, coated metallic construction.
I am asking $75.00 each, sold as a group only. I will include shipping free, insured via Fedex and properly packed to insure no breakage. If you have questions, feel free to ask.
