I just purchased these from Hockessinkid. They are too warm for my system. If you are looking for a warm tube with nice low end, these matched pair are it!

NOS pair of highly sought after RCA GSN7GT Gray Glass Stepped Black Plates which I have available. These were purchased from eBay seller Bullz Tubez. These are tested tubes, please see picture of test results below. You'll need an adapter for conversion to a 6922 socket. I can send additional pictures if request.

Pricing these at $110 which includes USPS priority mail shipping to the lower 48 states. PayPal preferred. Will pack carefully and shipped quickly.
