Wharfedale L32TA6A - Phihong PSM210-417A R issue
ANDRASONI:
Change all electrolytics caps( uF values) on the PSU. Succes!
dervdub:
Any more suggestions chaps? While I'm tempted to blindly fit new caps all round, I'm not sure there is much value in doing so - particularly as the 5v STBY is happy, but the 12/16/24v lines aren't and they spend much less time in action.
These seem to be a popular PSU, but I can't find one to buy and there's no info on them.
Hopefully Turnip knows something about them, I feel cheeky PM'ing him as I don't often get on here.

Hi
I did one not so long ago (similar fault) where every cap was leaky or had a high esr,
I know its a pain as every one just looks for bulgy caps these days but you need to change them all.
Good luck
Daz
cdel:
hi,
just want to know if there is 16volts written on your board ,as i know 24,12,&5 only.
dervdub:
Daz, thanks for the post - I've had to order some of the odd sized caps in so am awaiting delivery of those and will let you know my findings.
Cdel, It's not screen printed on the board itself but there is 5VS, 12V and 24V, but there is VADJ printed on the board.
It does mention the 16.5V line on the PSU label though - maybe the 16.5V 2A mentioned comes from the VADJ terminal (the set is in bits and some caps missing now so can't power it up)
I was tempted to inject 12 & 24v to see what happens, but chickened out as it's not my set.
