The Daiwa PS-304 has been with us now for at least 25 years…and most are still as reliable as ever. A great design stands the test of time and guess what…Martin Lynch and Sons are now selling the MyDel PS-304 Mark II.

Frankly it looks identical to the original and other variants…except for the pretty colours. About £100 new and half that second hand…or pre-loved or whatever you want to call it, they are a really good supply. The only problem is, none of the schematics I can find show any protection for your rig if the pass transistors go short…they can do this, and 20A of 20+ volts into your £2,000, 13.8V pride and joy? The smoke will definitely escape from multiple orifices.
Buy one for sure…but fit a crowbar to it before the big bang.
Here are the other two for your viewing pleasure (apologies for the gap between the pictures – I’m working on that):
