Crate BV150H valve amps

Likely a commonly occuring problem on the discrete wire IDC connectors, this
one 2003. The core and insulation of the screened wire is too thick for the
IDC metal. Presumably the IDC metal relaxes and only marginal metal contact
to pass factory tests in the first place. Only light finger force required
to lift the wire out of the trap. The screening contacts are fine, as just
heatshrink sleving on them.

There are about 10 such screened leads inside , with an IDC on either end. I
suppose the probability of 1 in 20 failing is quite high.
