Done a little measuring of the various resistors values. The left and right channels appear to be well matched but what's not so good is the 6.25-6.5% tolerance of said resistors, especially when you can buy much tighter tolerances of between 0.05 - 1.00% from HiFi collective. I've not bothered measuring the tolerance of the caps yet, that's another day. There appear to be 10 caps to replace, x2 Rubycon, x6 ELNA and x2 ThongX (??????)..... More tomorrow.
