For sale are 6SH7 straight pentode wideband RF or IF amplifier valves / vacuum tubes by Ken-Rad, in original metal Octal package, recently fully tested and working at 90%+ of nominal new emission. These devices were used in their many thousands in 1940s radio receivers and especially for professional and studio equipment.

Fully tested on my Mullard High Speed Valve Tester and showing zero faults and 90%+ of nominal new emission. The black paint is in good condition for age though has a few typical rust spots present. Original markings still present and readable.

A sensible price for these fully working, tested, original examples of a very useful quality valve/tube. Of interest to equipment restorers, experimenters and collectors alike!

TERMS

GUARANTEE: In case of dissatisfaction, buyer must return item at own expense. We will only refund if you return the EXACT SAME VALVE / TUBE to us that you have purchased, with the heater still intact and passing continuity test.

All returns under guarantee are limited to within 21 days of shipping.

PAYMENT: We accept all usual eBay payment methods. We are happy for you to collect from Bristol BY PRIOR ARRANGEMENT ONLY, but will require payment in GBP CASH on collection.
