[sdiy] ASM Capacitors/Bench Power Supplies

[Neil Johnson]

Steven,

1. Polystyrene capacitors are needed for the oscillators because of their
excellent low leakage and stability.  As is the way, they are therefore
more expensive than polyester or ceramics, which are fine in other places
(I use polyester for audio path, and ceramic for decoupling).

2. Rapid do a nice little unit, part code 85-1720, +/- 15v @ 100mA.  Costs
£41.50.  Has overload and shortcircuit protection (and indication).  Nice.

Cheers,
Neil
