Pioneer Spec 2 power amp question


Recommended Posts

I have a very nice condition Pioneer Spec 2 power amp, and with an inspection of its schematic I see that there is only one capacitor in the audio path. it is C1, right at the input, otherwise, it is all direct coupled.

C1 is a 4.7 uf 35 volt electrolytic cpacitor.

I believe this amplifier would sound much better with replacing C1 cap with one of the available film capacitors.

I have been looking at the WIMA MKS 2 polyester, and the MKP10 polyhprops.

Any input on this (not a pun) would be greatly appreciated.

Thanks, Bruce
