Re: Failing PSU survey anyone?

2005-01-04 by gonzinigonz

HI
I run my XL-7 off a 110v step down transformer from 240v here in the 
UK.
I ran it for a while on 240v but it did seem to get rather hot..
With no fan in there something will fail eventually in the PSU.
It runs a lot cooler on 110v
I have a Lexicon MPX1 thats the same.. PSU's can fail in those as 
well.
Maybe a fan mod (quite one..) is in order :o)
Regards
Gonz
