We have experience from the early 60's to date with most valve equipment from valve logic gate computer/adding machines right through to modern day FET driven output valves. A comprehensive stock of Eastern Block valves are available off the shelf and odd types like the 83 rectifier valve is still available as New Old Stock, as is the 807 and other types of older style power valves. All valves are tested before use on my calibrated AVO 160 Valve meter and selected for matched pairs and quads as required.
