Switching a Threshold Fet Nine/Ten from 110v to 220v

marcot · 18th January 2010, 09:04 AM

Hi everyone:

how is it possible to convert a Threshold Fet (9/10) from 110v to 220/240v?

Can I do that on my own or do I need an expert technician?

Many thanks
marco

if nothing else - you need to make good photos and post here - so maybe we can see something useful ;

if nobody with exact experience will not chip in .

Same old - almost all those products have dual primaries,
in parallel for 120V and in series for 240V.

Hi and thanks for your answers
Sorry if I asked something old, but I did not find any info on previous posts
Maybe my fault
Thanks again

Dear Mr. Pass could you also confirm that for Threshold S500? Does it have dual primaries and can be switched from 110 v to 220?
