REL B3 connecting to Linn Klimax Solo help...

Ok, then it does appear likely that it is faulty.

But when it is replaced or repaired, I would still suggest that to assure optimal sonic results you connect to circuit ground on the preamp, as determined per my initial response.

Hi Al

How do I do that on my pre, it has no ground plug....

Not sure what you mean by a ground plug. But in any event, proceed as I described in my initial response:

If there is a binding post or other terminal on the rear marked "earth ground," or similar, use a multimeter as I described to determine if that is connected directly to circuit ground. If it is, connect to that binding post or terminal.

If there is no such binding post or terminal, use the multimeter to determine if a chassis screw is connected directly to circuit ground. If it is, loosen that screw, wrap the ground wire from the sub around it, and tighten down.

If neither of the above applies, solder the ground wire from the sub to the ground sleeve of an RCA plug, as I described, with nothing connected to the center pin of the RCA plug, and insert that RCA plug into any RCA jack on the preamp.

Thanks Al, I understand now

Oh, how can I determine using a multi if its connected to circuit ground?? Ive never used one before.
