A quantity of two EF86 high gain pentodes manufactured by Mullard. Fairly clear chalky white print, mesh anodes. These valves were tested sometime in the past on a two panel AVO meter for mutual conductance and the following measurements were recorded; 2.1mA/V for the first valve, and 2.4mA/V for the second. The AVO manual recommends a figure of 1.8mA/V for a good valve.

See other listings, combined postage normally available dependant on weight, if winning bids placed on other items please do not check out until invoice is received so shipping discount can be applied.

Thanks for looking.
