[R-390] 26Z5W replacement

[Roger Ruszkowski]

Fellows,

What if we added a thermistor in with the diode?
It would limit inrush current.
Offer a bit of voltage drop.
Not be overly hot.

The few extra volts of B+ we get from solid stating the rectifiers does not
run the receivers out of their design range. 

I have no idea what a good part number or spec for the thermistor should be.

Charles,As always, thank you for your insight and thoughtful comments.  I reallyliked your past analysis of the choke input power supply.It looks like you have thought a bit about the problem of ramp up,certainly more than I have.  I could not see an easy way to do it from thepower supply end, which would be part of the point.  If I were going to doa lot of work, it would probably be to design a switching power supply, andI'm not ready to tackle that one today.I decided to move onto the main point, which is getting a working radio.JP
