Some of the bits, especially the high voltage, high current PSUs coul dbe very useful to us at BECG: https://auctions.ramco.uk/auctions/7316/...r%20Supply
Running professional vintage valve kit on the bench can be difficult without suitable bench PSUs. The HT current is often a lot greater than you need for domestic kit and you need good regulation. Paul Marshall is working on an early Marconi camera channel at the moment. I think the main HT uses 6x 5R4GY rectifiers in parallel (we need some and the audiophools are on to them), 12x 125uF caps and 5x 6AS7 double triode regulators, also in parallel. For test purposes we need to be able to run without that great lump of a PSU.
