WD/WAD HD83 Mk2

[Pingushome]

Hi ,
So after the kind help from snowman al and Bob, thanks to you both, the Maplin mains filter being built and I’ve now got the bug again!
I was thinking my hd83 could do with a brush up. There’s a very small in balance between channels and a slight russell when music is very quiet. Neither is enough to need a checkout really but I inherited it form a friend and it’s getting a bit long in the tooth now I think.
So I was thinking new caps/better, bigger psu caps, different diodes, and some Mills resistors for the bigger ones, check replace other resistors. Probably a pair of new valves too.
Or should I just go for the XL upgrade from Matthew?
Alternately I could go for the 3S pcb and upgrade it to a 3S. That was on the cards a while ago but then didn’t think, and still don’t think, I’d need the impedance matching anyway.
I’d be interested to know what others have done to their amps and the results. Any suggestions or thoughts on parts, makes, values would be gratefully received
Thanks
Martin
