I'm looking for a cheap and cheerful bench power supply. Here are the

Ideally, I would like:
0-5 Amps
Linear rather than SMPS
230/240VAC

plus a couple of 1.5V cells.
Gives you a dual tracking supply of 0 to +60V and -60V with single knob control and heaps of current available.
Hint: you switch the amp to "bridge" first.
**Nice idea, except I require variable current limiting as well. I
wanted to avoid a DIY exercise. In any case, I've pretty much decided
that a 30-0-30 @ 5A supply will do for the present time. 200 Bucks from
Rockby.
