Hi all - was trawling online looking at various Marantz 170dc restorations looking to see how some people replaced the dual capacitor - ended up using the catrafter method which worked well with clamps - however I did come across many 170dc photos that show additional capacitors fitted that look factory in addition to the dual capacitor - see example I found , this isn’t documented in the service manual does anyone know what these capacitors are for and if it’s worth while adding to any Marantz 170dc?

Bumping this thread...

I have 2 different versions of the Marantz 170dc. The first is a US version, which has no power button, has blue and red VU meters, and no numbering around the volume knobs. The second one which I acquired recently I believe is a Japanese version. It has a power button, blue VU meters, numbering around the volume knobs, and hence smaller knobs.

In addition to these faceplate differences, the Japanese version has the extra 2 large capacitors along side the dual capacitor. I looked at pictures online and this is consistent with this version of the 170dc having the 2 extra caps. This unit has never been worked on and it looks stock. Anyone know what the function of these extra 2 capacitors are?
