On offer is an extremely rare quad of 1950s Marconi military CV1075 / VT75 / KT66. All four valves are of the large ST coke bottle shaped clear glass with black plate structure, and bear the same red markings "CV1075 KB/Z".Fully tested on my AVO CT160, please refer to the photos for test results. All four valves test superb! Note : AVO valve data manual specifies an average reading of 65mA and 6.3mA/V for KT66 (+250V, +250v and 15v negative bias voltage). All four valves are in very good clean condition. The valve second from the left has the words "H294" lightly scratched on the valve base. The valve on the extreme right has a burnt mark on the top (note : this can be clearly seen from the pictures). The second valve and third valve from the left are in absolutely MINT condition with no signs of usage at all!Please note that the red markings "CV1075 KB/Z" on all four valves have different degrees of wear, but the markings are still highly legible and are in very good overall condition. Please note that I do NOT ship to Vietnam, Russia and Italy due to experiences gained from the past. As these are large valves and they do not have their original boxes, I will be packing them individually using PVC pipes. Postage is by Singapore Post registered international mail and is a flat rate of US$25 for all destinations. All four valves are guaranteed to work. However, as with all vintage valves or tubes, I do not offer any warranty in respect of sound quality as this is a hugely subjective matter. Also, as no two valve testers even if they are of the same manufacture and model can guarantee the same test results, i also do not offer any warranty in respect of the test results of the four valves. I have been a long time ebay member with 100% positive feedbacks, and I intend to keep it this way. Thanks for looking.
