Default Pioneer C-Z1 pre amp

Having recently received one preamp for evaluation, the Pioneer C-Z1, I noticed it is wired for 100v.

It is a heavy machine with a massive psu including very good components but all the el ones are covered with glass... Does anyone know about replacements ? (I did not touch it or powered because I do not know if it can withstand 110v ~ 120v so any comment would be very much apreciated).

Does anyone have any experience on this no NFD with super regulated psu design?

Of course a schematic would be gold....)

100V suggests suitability for some areas of Japan. If you feed it with 110 - 120V then the transformer output would be nominally 10 - 20 % high. The transformer / rectifier / smoothing capacitors / regulators may be totally fine with that... or they may not be !!!

My best guess is that it would be OK.

However, if in doubt buy a 'Variac' variable mains transformer and feed it 100V.
