NO, it's the power cable for the display pcb. It's white instead of black! Much better sound

Anyway, this particular player is scrapped

some time ago. Needed the display controller to fix a CD60.

The not one and only

I have still-stock

Philips CD50 (mfg date January 1990) that looks very similar inside. Same main board, plus another board mounted on right side with Variable Volume RCA outs.

I know this may not be the correct thread, but for bypassing of +5V rail on SAA7220 what would be better: Black Gate NX 33u/16v, Black Gate NX 220u/6.3v, Panasonic FC 220u, or OSCON SP series? Are OSCONs still being manufactured?

OSCONS are still in production... And they are industry accepted, don't know if this applies to Blackgate aswell ...

weissi,

the sanyo web site show several series of oscons (SP, SG, SH, SC, SEP, etc...). which ones are best suited for this application (digital rail bypass on SAA7220 and TDA1541) ?

thanks,
Bruce

SEP - < 10µ are really sufficient (unless you plan to fit a smps into the cd player

)

One of the guido's was recommending Oscon 220uF, but what series should i use?
