Wolf ... I checked eBay. Right you are. Number of vendors offering to sell KT-150s for prices you mentioned above. Even still, I have three concerns.
First is that ARC hasn't approved the tube for use in its amps yet. I suspect that the additional current draw is not signficant, but I don't want to experiment with my amp.
Second, my amp requires matched tube sets. I've had some difficulty in sourcing pairs that match well. So far, only ARC has been able to provide reliable matched sets.
Third, I do not know anything about the reliability of the eBay vendors. At least with vendors ARC and Upscale Audio, I am comfortable that the tubes are properly run in and tested before being sold.
In short, it might cost me $700+ to buy 2 quads just to satisfy my curiosity .. although I am curious about the tubes.
