As far as I know, this is one of only a small handful of Crack's which has been built to run a 5687 / 7119 tube, and one of only two in the wild which can roll back and forth between 5687s, 12AU7s, 12BH7s, and E80CCs. For those unfamiliar, the 5687 is a very well performing tube with generally better specs than the stock 12AU7s and incredible imaging. I still am enjoying putting work into this amp, but I've had my eyes on some other DIY kits, so if the price is right, I wouldn't mind letting go of this beauty.

Best,
-e
