On offer is one only Valvo ECC83/12AX7A used tested - test strong near new - printing is quite good considering that the printing on these vintage valves seems to evaporate before your eyes at any attempt to clean off the dust - the valve has the date code Philips Heerlen Oct 1962

My AVO MKII valve tester gave the following results

Shorts:- nil

Gas:- pass 

Heater Cathode leakage:- over 10 Meg Ohms

A final test on a RAT tube tester confirmed the following specs - both sides being closely matched and within tolerance for a new tube, this tube will not dissapoint.

Side 1:- anode/plate 1.50mA & Gm 1.5mA/Volt or 1500 umhos

Side 2:- anode/plate 1.51mA & Gm 1.5mA/volt or 1510 umhos

Where new valve figures are:- anode/plate 1.2mA & Gm 1.6 mA/volt or 1600umhos.<br>
