hi fellas greetings from the philippines. i rebuild pioneer stereos from the 70's as a hobby.currently im waiting for caps and transistors to rebuild a qx949. i owned one of these new in '74 and tho 4ch never really succeeded i have a soft spot in my heart for this receiver. the one i have was rather beat up but cosmetically it will regain its former beauty. the seller said it didnt work but after a deoxit treatment to all the switches it all still works without any snaps crackle's or pops. of course the thing is loaded with 2sa725's and 2sc1312's that will all need replacement during the recap for longevity. the fly in the oatmeal as it were,is the service manual only lists adjustment for vr1 and vr10 for the cd4. there are 8 other vr's that will all need adjustment after that board is rebuilt. do any of you fella's know what the procedure is for adjusting this board? or failing that, can you point me to someone who does? i am an active member in audio karma and have posted this question in the pioneer forum but havent yet received any useful replies any and all comments are welcome,regards JOHN
