Other than the usual caution about capacitors in power
supplies, the
TU56 does suffer from deterioration of the motor run capacitors (these
are quite different than motor start caps). The often need to be
replaced and are fairly expensive (I seem to recall that mine were
$25/ea and there are 4). They are also a bit difficult to find.
If anyone has any other suggestions (or sources for motor run caps), I'd
be interested too.
I used a Vanguard BC-108 (108-130mfd 110-125VAC) to replace one of mine that
had leaked. They shouldn't be hard to find.
The physical form factor is different (smaller), so they don't look like the
original equipment, though. I just wrapped it in tape until the diameter
was sufficient for the original clamp :-).
