Hello,
Does anybody know where to get schematics for a NAD 502 CD player?
I found it broken on ebay, and figured I have to start somewhere so this will do, for $70AU.
I'm buying some lowish priced upgrades from a place called Burson in Melbourne (clock, op, shunt reg)bit by bit to suit my frail little budget, but what I really want to know is what sort of power transformer should I think about upgrading to?
I plan to run the clock on a seperate DC power supply and get a better one for the rest of the player, but I know neither of which to buy.
And I decided not to get a seperate DAC for the time being too, again, budget.
Anyway I'm looking forward to buying one bit at a time and trying to hear the improvements with my own ears.
I got a good preamp, headphone amp and HD650s.
Any power-supply/transformer suggestions for a guy that can spend maybe about 150AU a week?
Capacitors, too.

hey, I got it! from vintage manuals dot com
but I think I accidentaly threw it out, and have to get anoter.
Anyway, vintagmanuals.com does it for around 20 bucks.
I'm gonna try this cheap ebay low jitter circuit and maybe burson ops and shunts...mid price gear from Melbourne Oz
Oh yeh, gotta get it to PLAY A DISC yet.
