NAP140 on steroids

I don't know whether to put this in here or the main classified room.

I have a shoebox amp that I built myself and served as a pre-prototype for the Witch Hat amp. It's taller than a Naim box but roughly the same width and length.
It comprises:
2 x NAP140 boards with 2sc2922 output transistors and 47uF film feedback caps
Avondale minicap6 power supply with 10,000uF Kendeil capacitors
Canterbury Windings 300VA 30-0-30v custom transformer with shield winding.
4 pin DIN and RCA phono inputs, but no pre-amp supply.

It's been poked and prodded a bit and currently has a passive Alps Blue 20k volume pot wired in but no front panel. There's a pushbutton switch in the front.

I'll upload photos later.

Is 450 a reasonable price? Contact me through PFM please.

Tidied up. I have removed passive volume control and put a front panel on it.
This looks like a finished amp and is in the main classifieds now.
