Lets just say that they dont win any engineering awards and leave it at
that. Neither are the PS immune to failures.
Even Heath ran bare naked diodes in the SB series even tho the ancient
design diode current ratings were pretty close to the edge. The failures
there are usually traced to turn on surges thru leaky caps bringing peak
current into the failure zone. Or long key down tune up in the SSB
position plus the same leaky caps.
