Don't use Farnell because of the reason you both state i.e. order size.
Replaced the 220uf servo board caps with 470uf ones I had to hand and that has improved things somewhat but I am now going to replace the remainder. Is there a preference for the two 100uf caps in the signal path? Rest I will just replace with generic (nothing special) caps. So long as I don't use ultra-low ESR ones on the regs, all should be OK methinks. Can't find anything of 6800uf with an earthed can though.
TIA,
AP
Mike,
Thanks for that. I decided to go for the fine gold as they have a good rep and was a bit concerned that something much smaller (poly film) would sound rolled-off with 4k7 loading on the output side of these caps. To be honest the old ones in there don't actually sound too bad.
Richard,
Received and fitted the display last night. Does the trick nicely thanks.
Got some caps ordered for fitting at the w/end.
Thanks guys,
AP
