Melos 202 could use some servicing...


Hello,
I recently purchased one of these units, originally a 200 updated to 202 by Melos audio restoration way back when they were in business, there's been an issue with V5. The tube intermittently redplates. If I turn the power off and immediately back on it resets and once totally warm it will be fine.
I need a schematic to get it serviced. Does anyone have or know how I can find a schematic I can provide an excellent local engineer with so I can get this awesome sounding amp into perfect working order?
Please help
Please!
This amp should not be allowed to die

I heard back from Mark. It looks like Melos is planning a return...
He was able to offer some advice regarding the mosfets used that tended to over heat because of inadequate heatsinks...
My local guy still wants a schematic so he can pinpoint the exact issue rather than working from a suggestion

To that end it's been suggested I try to contact George Bischoff who designed the circuit. I tried contacting him through george mark audio, which has a live website but from never ending rings and emails that bounced back immediately seems to no longer be a functioning business.

Does anyone know how to get in contact with George these days?
I'm excited that there are future upgrades coming through a new Melos but still want to get the amp running properly as it stands today.

Thanks
Did you try contacting Mark to see what he has available? I am in New Jersey and could take a look at the amp if you are close by. Email me at Vujadeaudio@optimum.net
