I remember back in the days of the first vcrs. A Philips 1501 would cut out
for no apparent reason. In the end after much messing about running it with
the bottom hinged down, two Mullard rectifiers were removed from the pcb and
found to have lose wires in the green/blue mouldings on one end I took out
the other two as well and replaced them with an assortment of reclaimed
rectifiers culled from old junked gear and never another problem. It seems
to me that when companies first started to encapsulate things the movement
under heating and cooling over time was a common failure mode Since then
before I lost my sight, I have had cause to change these Byxxx rectifiers
many times in equipment.
This component will self destruct in 4 years.

My ancient workshop amp failed. Took the mains fuse - and a replacement.
It was assembled from bits I had lying around - including a mains
transformer I've not quite sure what it was made for. And of course it's
always the most expensive bit that fails...

Turned out to be the rectifier. Nice cheap fix - had a spare.
