[Amps] Re-imagining the 30S-1

[Martin Sole (HS0ZED)]

Well  not quite but...

I've got a bit of a basket case 30S-1. Much of the power supply iron may 
well be junk. Sat submerged in flood water for well over a month and 
that was a few years back.
Getting toward thinking about reworking it I'm wondering if I can 
improve things a bit. Not in terms of what it was but what it might be. 
So if you were rebuilding such a plate supply would you still do it the 
same way, centre tapped trafo, tube rectifiers, resonant choke filter, 
big bleeders? Or is a more modern approach, single secondary winding, 
bridge rectifier and stack of electrolytics more the way to go?
Though there's quite a bit of interlocking and protection in the way the 
power supply is arranged it all seems fairly straightforward.
