I seem to be getting a wee bit of bias on the left channel, and suspect the valves in the X10V3 are on the way out - MF quote essentially 1 year continous use, and given mine hasn't been switched off in 2.5 years, it's probably time to check the valves.
Is there any simple check I can do with a multimeter to check their health - I've opened her up and both valves are glowing (always a good sign) - but in comparison with my analogue set up the output is definatley (too my ears anyway) louder on the left and quiter on the right - so I suspect the X10 V3 because it adds a dB or two to the output when in play. if one valve is on the way out this may account for the quieter output thorugh the right channel (not being attentuated?)
Ideas?

Ideas? Sol You can't readily check a valve's emission with just a multimeter. Try swapping the valves over and see what happens. Alex |

I considered that ... but the valves are hard wired in on the X10 V3 ... thought I'd check with the forum to see if there were some measurements that could be done before resorting to a soldering iron!

Oh Sol,
Say it ain't so! The 6112s were touted by MF as having a 100,000 hour lifespan (from my feeble memory; I need to verify). That's about 11.4 years. My X-10 v3s have to last me the rest of my life so I hope that that estimate wasn't BS. Keep us posted and good luck!
P.S. I assume you've determined the X-10 was the culprit through channel swapping. Forgive me for asking.

The 6112's are only a fiver each I really don't see there's that much of a problem..... they are easy to solder in.
