I have a few vintage solid state amps and receivers that I bought between years 2000-2010 but almost exclusively listen to my tube amps for a few years, they sound a little less "congested" to me, + I can roll tubes to find the better tone and wamness-softness combinaison.
I restored some solid state stuff, replacing all electrolytics, trimmers, but upgraded the tube stuff with decoupling capacitors.
I will do some upgrades on this one too, as I do to almost everything that I own. if this is an easy fit, I will add one or two 4.7uf 630V CBB capacitors + one 0.1uf 1000V Ceramic disc directly to the big B+ cap, and will look to add some of the right values to other electrolytic caps for exemple: a 4.7uf 100V CBB to a 25V electrolytic, and maybe add some Ceramic disc caps there too.
There is someting like 14 electrolytic capacitors inside this amp and it's all point to point, cannot find an easier work to do.
This will tend to get the amp very fast , dynamic and silent.
I will bypass all electrloytics with decoupling capacitors except the ones between the rectifier and the choke, and the coupling caps.
Sure it will sound fine.
