Weird popping/splashing sound coming from my tank...any ideas?

I've got a Gomez G-spring and it is constantly making little popping/splashing/dripping sounds, irrespective of whether I'm playing. I can hear that the noise is coming from the springs - it's as though little charges are intermittently being sent through the springs causing little blips and pops, or vibrations are causing momentary jolts - but I don't know what could be causing that. It's also generally quite noisey/hummy too. I've tried different preamp valves, a different power valve and a different reverb pan but to no avail. Any help would be really appreciated. Thanks! Top

I've seen this problem in a combo amp that had an arcing reverb driver transformer, but that should only happen in a vintage unit. Leaky coupling caps will make this sound, however, new coupling caps don't leak. However, some companies like to use 'new-old stock' components because they are extra-vintagey, but those are at risk of leaking. I once pulled a leaky C-D cap from a Blues Land boutique amp and replaced it with an ordinary film cap. The amp's owner was much happier afterwards. I don't know if Mr. Gomez is using NOS caps but after my experience with the Blues Land, I haven't used anything them in anything that anyone has paid me for. — If it ain't broke, fix it until it is.

My amps make a lot of parasitic noise (hum + random popping) when I use them in my apartment because the electrical installation is a mess. They work fine in the rehearsal studio. — Old punks never die... They just become surf rockers. Top
