Two-Rock TS1 / ELI Ground Loop Hum nightmare

[Rollylama]

I just had the time to read back thru this whole string and it was the powering of the filament with DC that killed the hum in the units output.

So he either in the end converted the units ac filament power to dc ( plenty of room for that in there)

Or he put in a jack in both his amp and the unit to bring in his amps clean filament voltage to run the unit on I don’t know which way he ended up going with.

I wonder if he is going to now offer a mod kit for these units and that’s why he has removed so many of his post here and also not responded to any PM’s.

With the cure now known there are numerous folks on this site who could do this mod on these units, I would offer you such if it where not for having more then I can chew right now for likely 2 months.

I appreciate the offer but I sold it. I’m on the hunt for a functioning loop now. If I can find someone to mod an ELI I might give it a shot.
