As most people do from time to time, I've been snooping around ebay to see if anything interesting turns up and I've noticed a few H|H studio amps, most of which seem to be ex-BBC mono-blocks. Nobody seems to be snapping these up so they can be had for next to nothing. They don't seem to have much oomph (some are only 25 watts), but other than that I don't know too much about them. Does anyone have any experience of these?
