Out of the clear blue, this weird anomaly comes up . . .


About two weeks ago I started hearing an intermittent static sound like a TicTic tick sound coming from the left speaker. At first it was most noticeable from the left speaker and I thought it was microphonics & I was going to change out one of the input or driver tubes to try and troubleshoot Just tonight I noticed that it's coming from both speakers and directly related to when the thermostat calls for heat . . WTF?

The only thing that has changed in my system in the last three weeks are brand-new KT-120 tubes. Clearly, toobs are not the issue.

I wanted to run dedicated lines to each monobloc anyways, but this may force an imminent upgrade. Any ideas what's going on??

As always, TY in advance!

    What's weird is that the ticking is just like the boiler igniter trying to light up

    It does appear to be directly related to the boiler ignition process, once the burners have lit-up, the static to the speakers goes away . . . HELP!

  • Are you using shielded power cords?

    Don't you love issues like this. I have a dedicated 20 amp line in my HT, and all the electronics use it. When my microwave in the kitchen is in use, one amp vibrates or hums. I think it is the transformer in it. Go figure.

  • Aah this type of stuff will drive you crazy. My amp's tranny will hum every night from 10:15 to 11:45 like clock work, but also intermittently on occasion. Figured it was dc so I purchased the Emotiva cmx-2 which is a power strip that removes dc on the line. That solved the problem, but what is weird is if I plug my panamax into the other outlet on the cmx-2 then my amps tranny begins to hum again at a low level. Good luck figuring out your ticking problem, I am about ready to go with a dedicated line as well, since my system is only 10ft from the breaker box and on the same wall it should be an easy diy.

    The noise is coming through the shared ground. Get a cheater plug or however many you need to lift the ground where your gear is plugged in, which should get rid of the igniter noise. If it does, install isolated ground outlets with the proper wiring.

    Bud, you likely have the same issue.

    Would a shared ground most likely be inside the panel board where two or more grounds are doubled up on the Buss Bar??.

    I think this may be the ticket, because I know they're all supposed to be separated and secured individually, not double tapped at the neutral or ground busbar

    feel free to chime in . . .

    Probably. The strange part is the microwave is on an original, 1958 shared ungrounded (two wire) circuit, while the amps are on a dedicated, grounded circuit. I have new speaker wires on order, and when I install them I will open the amps and tighten the transformer.

    I believe the grounds are all tied together at the bussbar regardless.

    In that case, I'd say you have a different issue.

    That IS really strange!

    Me thinks the only common denominator left, is what's shared inside the panel board. I'm still siding with the camp that thinks ground and neutral wires should not be double tapped at the busbar . . each hold-down screw/fastener should only secure one where each

    You may want to check the ground connection in your boiler also. Will be in the area where your line voltage enters. Should also check the gas valve ground.

    Both generate a lot of noise.

    Not exactly sure what you mean. I really appreciate your input but please be a little more specific.

    I do not see any green or bare copper wires anywhere near the boiler

    Inside the machine. You may have to remove an access panel to see where the line voltage connects to the high voltage for the machine. If the ground is wire mutated to another wire, follow that wire until you find where the ground connects to the machine.
