Thanks It's fine on batteries so I'll use those for now. Unfortunately those service centres are a long long way away from where I live so I'll have to keep them as a last resort

Thanks. Yeah I've already tried cleaning the contacts. No change.

Thanks for your reply. I've cleaned the sockets several times using Deoxit and have also run a jack burnisher in there gently a couple of times. Doesn't seem to sort it. I've got one of those USB to variax boxes and tried powering it via that and the VDI cable but it didn't seem to power the guitar up. .....

Noticed that lately my old variax 300 has got noisy when using the xps mini power supply. Years ago when I had valve amps we used to call the sound "blowy" - white noise of varying amplitude with a bit of crackling thrown in. Tried a new PSU on the XPS and also a new balanced cable between variax and xps mini. Noticed that rotating the plug withing the socket on either variax or xps end creates a lot of noise but thought that might just be normal seeing as how the power is running through that ..... Any ideas on a fix? If not, any other ways of powering it without going through tons of batteries?
