Re: Power Supply Capacitors
Modern resistors dissipate their power in smaller packages than their forebears by running at higher surface temperatures.
Choosing higher power resistors in big packages is a good recipe for cool running and good reliability. Modern resistor materials may be OK at the higher temperatures but they can cook things around them and make solder joints go granular. David

Re: Power Supply Capacitors
Why not modern film caps, or are these paper ones cheaper? A quick look gives 4 X 6u8 @ 400V for ~£10

Re: Power Supply Capacitors
Two bleeds one with a neon and one with an LED? Put them (the lighty up bits) on the front panel too. Mind you I have never had a good old mains neon fail, just one of those on the front should suffice.
