My amp suddenly going silent when volume knob touchedi have a ordered

Very interesting to see what possible causes could be. I'll to try grounding myself first. If no help, than tuner cleaner would make perfect sense. Thank you.

I was in the high-end audio business for many years.  This has happened many times in my experience.  Especially this time of year when the furnaces come on.  They tend to produce more static electricity in the air then at other times.

Also, if you are wearing socks, they will pick up the static from the carpet and pass it through you.  I have solved this by wearing rubber soled slippers or spraying the carpet with an anti-shock spray or grounding myself, (touching a metal post on my rack) before I touch the unit.  Any unit that uses some type of a logic chip can get zapped whether it's for volume or switching or DSP functions.

We had a thread on here several years ago about this same thing, but I can't find it at the moment.

I've also never heard of using tuner/contact cleaner to solve this?  If you had a scratchy or noisy control, yes, but not this particular problem. 

mofimadness4 and xti16,

     You guys are right, deposit buildup just causes a scratchy static like sound but does not cause the unit to shut down.  
     Sorry, it was my fault.  I think I must have misunderstood the symptoms on the original post.
Thanks,

Wish I had a dollar for every post I initially misunderstood LOL!!

Sold my 1070, have had a few different  brand amps in here with no issues. Just picked up a nice sounding  vintage Rotel RA 1060.... same issue. Zap, no sound, LOL. Must be Rotel, other brands not exhibit, same living room, same conditions.
