Convert a Pass Labs x350 from 110v to 220v

emdaudio · 2nd March 2011, 07:49 AM

Hi there!

I'm from Argentina and I want to buy a Pass Labs X350 power amp from the US market (audiogon)
So, is there anyone that know how and whether it's possible to convert the ampli to the EU voltage/Hertz i.e. from the 110v/60Hz to 220v/50Hz?

Thanks!!!!!!!

X350 had a dual tapped primary transformer. For 120V
operation the primary taps are run in parallel and for 240V
they are run in series. A competent technician should be
able to make the alteration.

Ha, you wish. But a competent tech will have no problem spotting the correct taps. I wouldn't be surprised if it is even marked on the silkscreen. Soldered or screwed?
Here's how it probably looks inside: Pass Labs X350 Inside - micsp15's Gallery - Canuck Audio Mart
