Re: VECTOR: 6101 deflection board parts

The 1N4000 series are slow as death 1 amp rectifiers meant for 60 Hz 
power rectification and pretty much nothing else.  Unfortunately people 
have a tendency to stick them in places they don't belong.

This is one of those places.

Stick with the 1N5402.  Is a 1N4007 (1 amp, 1000 volt) a replacement for 
a 3 amp part?  Not really.

This part information should be added to the troubleshooting flowchart 
(since the manual is no help in finding the correct replacement), if 
anyone has a way to do that.
