Melos SHA Gold - what may be the fix..

for my preamp that will not come out of mute mode?

Remote control must be used but can get no response from "power" (in effect the on switch). The manual descibes as "play mute off". The remote does still control the other functions such as volume motor.

What may be the problem and what techs should I consider sending the unit for repair?

hi, for what it is worth when i had a melos sha gold and melos audio restoration could not fix the problems i had i contacted george kaye (now of moscode tube amp fame)and he was able to fix the unit and was familiar with the circuit in the melos tube preamps.

I sent an email to George Kaye. No response after a couple of days. Thank you for the suggestion all the same. I have enjoyed reading yor other posts. Folks who contribute to
the knowledge and helpfulness at this site are second to none.

Don't want to ask a stupid question, I know nothing about melos, but did you try unplugging for a while? Just in case it's just a matter of re-set. Just ignore me if this is too obvious.

I did leave a little info out. I had a BAT VK-31SE and I had some issues, when I called BAT there was a re-set sequence that the ran me through and that fixed my issues. It was a matter of holding two different buttons and shutting it off at the same time.

thank you. I will go through and check fuses and see if
I overlooked any thing of the kind you suggest. Certainly no mention in the owners' manual.

Seems to me I recall reading a post mentioning some kind of photocoupler or a photo related replaceable part that can burn out????
