I'm in the same minority as jazzandmetal? I think the stock VJ sounds fine, no real need to change much. So....
I'll be rebuilding my VJ head in the next few days. Stock circuit, nicer parts on two turret boards. I'll post pictures and build report once its done.
cheap and easy:
replace filter caps.
more expensive and time consuming (better results):
replace all filter caps, coupling caps, cathode bypass caps, clean/replace pots as nec, clean/retention tube sockets as nec, reflow any suspect solder joint, bias power amp and replace/redress all wires...
