A wise woman. Whats she doing with you?My other half often says,' what's that strange ringing sound?' I always say, 't'is ok, it's the caps in my amp vibrating.'
I hope it's not as painful as a kidney stone...So does Russ Andrews, Peter Belt et al.
I can feel a Shakti stone coming on.
Most of this thread is about as painful as passing a kidney stone.I hope it's not as painful as a kidney stone...
I don't have an "other half" but I do get strange ringing noises from instrument amplifiers (in particular: Selmer Treble'n'Bass 50, Marshall Bluesbreaker combo re-issue), I think it's the insides of the valves getting a bit loose. Not had it on Marshall amp heads or on the Vox AC30.My other half often says,' what's that strange ringing sound?' I always say, 't'is ok, it's the caps in my amp vibrating.'
I trust that's an attempt at a joke.A wise woman. Whats she doing with you?
All that time I spent thinking it was the transformer, sticking grommets underneath it, buying DC blockers, mains conditioners and battery power supplies,My other half often says,' what's that strange ringing sound?' I always say, 't'is ok, it's the caps in my amp vibrating.'
You may have more success sliding an O-ring over a cap that's standing on the chassis than a smaller signal cap because the latter is likely to have a wire sticking out of each end which is then soldered onto somewhere.Serious question here, no sarky answers please chaps, if I was going to treat my caps, will I get a better result from doing the big PSU caps or the small "signal" caps? I'm thinking my 'O' ring idea here.
Try them all! But I would guess the PSU caps....Serious question here, no sarky answers please chaps, if I was going to treat my caps, will I get a better result from doing the big PSU caps or the small "signal" caps? I'm thinking my 'O' ring idea here.
You guess? GUESS??Try them all! But I would guess the PSU caps....
Suggestions on the back of a postcard...We need a detailed explanation of exactly how much tape, what shape it needs to be cut to and exactly where it needs to be stuck
I do know where he can stick his commentSuggestions on the back of a postcard...
My contention is those products you mention are NOT equivalent...If you insist on trying it then dont waste £60. You can get similar or even identical foil backed butyl stick on panels for a lot less. I got 5 sheets
30cm x 40cm x 1 mm thick for about £20 off eBay. Alternatively try Dynamat Extreme or even 3M. They all work on the constrained layer damping technique in which the attached damping panel material is worked in shear by the offending panel vibrations. Its in shear because these panels have an outer foil constraining backing. The damping material used is chosen to have high conversion to heat when operated in shear. Sorry to tell you but there is no magic in this its been around for a long while.
As to vibration causing sonic effects in electronic audio equipment Ive only come across two measureable effects. One is with some clock oscillator
crystals and the other is with transformer laminations if they are not packed tightly enough or potted. Ive not seen anything with the capacitors Ive tried although I did see some strange tape applied by Sony to some Elna Silmic caps in a SACD player once but this didnt seem to have any measureable effect .
