NOW ASKING $45. Class A Headphone amp in a mint tin by XRK971 back when he was selling fully assembled amps vs. just boards. Tuned to support 50 Ohm cans, build #37. There is a review out on the interwebs that features #36. The tin looks horrible, I was trying to improve cooling ventilation, that said the amp is fully functional. I can send extra pictures if requested and I have copies of the purchase/build conversation with XRK971.

How can you put a price on something that took a bullet for you?
LoL, that's what you get when you don't think about what it will look like afterwards. It did run cooler but I could have just kept the lid open.
With class A operation it's not very efficient, about 4.5 hours. I used rechargeable 9 volt batteries so they have less capacity than the alkalines.
