Hello
I discovered many interesting topics here. I'm a tube lover and I presently refurbish Melos monoblocks amplifiers. As nobody has schematics of these amps, this is a lot of job. Now they play well but they are not the best for reliability. There's near 600 vdc on them and as the traces on the boards are near one to another, I had sometimes sparks on the boards. By the way, is there an isolation paint to correct this situation ? Thanks.
