These tubes have under 500 hours on them. They were used in a circuit that has a slow start cathode heater circuit (1m 20s) and a time delay for the plate voltage. Therefore the tube has had very low stress thermally and no cathode stripping. I am selling them because I just like the sound of the solid plates better. A new pair are $625 plus shipping, etc. I am asking $495. I prefer Paypal. They will be shipped in the box that I got them in. Original box can be seen in the photos. I am in the Albuquerque area. I will ship via USPS or UPS.
If you are interested I can send you my Ebay and Adiogon monikers for feedback which is excellent.
