For "sale" is the bare working circuit for a Korg NuTube B1 I bought and built from the diyaudiostore, with an additional power conditioning board, Mark Johnson's PO89ZB, I added separately. I repurposed the chassis, the switches, the pot, the RCA and power jacks, and the wall wart for one of Papa's B1s so I have only the circuit available. This B1 Korg was working and stable when I pulled it, and very rarely had any microphonics. Please don't complain about the solder joints though, not all of them are pretty!
Now here's the catch. I will "sell" this to anyone in the continental US who can show me a receipt for at least a $50 donation to diyaudio. It's fine if it's a month or so old but I'd rather it be recent, as in since the site upgrade. So if you want this thing & have such a receipt, talk to me. Happy Tuesday!
