Up for sale is my spare pair of brand new, never used old stock Phillips Holland 6SN7GT Platinum Grade tubes. These are one of the "Holy Grail" tubes that are virtually impossible to find. There is only one place that I know of that have these tubes and that is Upscale Audio which is where I purchased them. Kevin at Upscale will only sale these tubes if you have purchased equipment from him. They have only been taken out of the box to take pictures and immediately put back in the box. Thanks for looking.
