10uF coupling Tantalums were replaced like for like with Kemet beads. Rail decoupling for Sanyo OS-con 47uF. Feedback pre/power replaced with 47uF Nichicon KZ. Output Transistors decoupled with 470uF KZ's. BHC/Kemet ALC 10,000/3,300uF for PSU. Removed the Phono boards and replaced the Mica/paste for new as they were past their best.
Initial impressions were disappointing. I thought I must have a polarity wrong somewhere but I triple checked everything and all was correct. I left it playing on loop for an hour under load and there was a vast improvement, strangely though it seems to have lost the edge on the mid kick it had and the low notes seem to be a bit much, but worth the time if only to know the reservoir caps are within spec. Suppose time will tell on the rest?
10 months have passed and all is now good with the 90/90.3 - fantastically musical for the outlay. Thanks to Misterc6 and PFMM Martin Clark at http://www.acoustica.org.uk
