I have a spare Neurochrome 21st Century Maida Regulator surplus to my requirements;
Product information is available here;
21st Century Maida Regulator: A modern B+ voltage regulator – Neurochrome
It's fully assembled and tested, configured for 300VDC @ 50mA but easily changed by swapping out two resistors. I'll include an additional PCB for the rectifier and filter cap required upstream of the maida reg.
£40 plus shipping at cost plus paypal fee.

Just happen to need one for an Impasse preamp, and this was a very attractive price. Congrats on the lightning-quick sale.
