Musical Fidelity M3 integrated

This amp is now a little long in the tooth I suppose. But I still love it. Mine is 100% original. I wonder how to change/upgrade the internal jumpers with something better and where do I buy new jumpers?

Other suggestions on how I can spueez better performance fron the unit?

Thanks.

Good move, mr Manitunc. May I ask where to buy a spare set of nuvistas at a good price? I can see I'll keep my M3 for a long haul as well.

I must say it's tempting to send it to MuFi for an uppgrading, but it's quite exspensive...

I bought some also by searching the web by the part number; they were quite cheap for NOS parts. I would not have MF do the upgrade.

An update for those who are interested: As a precaution I've installed the new nuvistors (rca 6cw4) and replaced the ICs between pre-power as well (with 0.5m kimber pbj). It was a fairly easy job. No soldering at all. The amp is playing now. guess i'll have to wait for the tubes to "burn in" (for how long do you think?). As it's right now I can't tell any improvements.

Couldn't located the mm/mc but I'm in no hurry in this matter.

Thanks for your kind help :)
