Default Philips CD350 TDA1540 muting caps


New to the forum, looking for info on how I can 'snip' the muting caps. I presume the PCB used in the CD 350 is the same/similar?? to CD 104, CD150 etc. I really need a pic of the actual PCBA position as I cant read schematics (although I know someone who can if that helps).

Ive already snipped them on my Nakamichi CDP-2 (TDA1541), as per the excellent Lampizator pictures on his web site, easy one. Made a positive improvement,

No nothing yet, I also have a PS Audio CD-1 which is based on the Philips CD-350, might take the lid off and see if they snipped the muting caps. The PS Audio CD-1 sounds nice, but just doesnt have the get up and go of the standard Philips machine, in comparison it has bigger bass maybe, but a bit over smooth.Think the PS Audio will be up for sale soon.

CD150 muting transistors are surface-mounted on the underside of the board. They are the four, three-legged parts between the audio opamps and the audio output sockets.
