Default Linn Axis PSU overhaul

Hi,

I have a working but tired Axis PSU (011 Rev3).
I'm about to replace:
2x 47microF 250v
2x 220mF 16v
2x 33mF 350v
6 x22mF 50v

I intend using larger voltage versions.
The parts aren't temperature labelled; do you think it's worth having higher temp rated?


Other parts:

Is there an advantage replacing any of the following:

* R1, 47ohms +/- 5% [Someone mentioned putting in 2 varistors(?) but that sounds like changing the board layout, which is above my confidence level]
* Bridge rectifier.
* Two physically large resistors printed "273-0, 15k, 5%" ?

I don't know the wattage ratings for any of these.

Have I missed anything? I'm not an electronics whiz, but I'm good with a soldering iron. I know the board is dangerous and easily damaged.

It would help to see a circuit tbh

Always worth getting 105C rated caps if possible if it's hot running. Even if actual temperatures are below this the higher rated parts last far longer.
Make sure any replacements fit physically as there is nothing worse than seeing parts with bent leads trying to make them fit.
