VALVE RATTLE hey i know it happens but whats the go - is it bad - do all valve types do this? how can WE get around it, it doesnt happen in any other valve amps. cheers all | ||

If that the rattle you describe originates from within the valves (lite tap on them -while cold), then your valves ought to be replaced with a matched set and biased. Try playing with a bit less bass. (BTW, slight rattle can be normal.) If the rattle originates elsewhere, try doing some 'general tightening' - cabinet screws, speaker's, chasis retainers, etc.. If it's from a speaker, you may need to replace. If it's coming from within the chassis, bring the amp to a tech, to avoid getting fried - or worse. | ||

my hd130 tubes also rattle. which is fine when playing loud and can't hear it, but a pain in hte arse when playing quietly. can it be stopped completely? | ||

The insides of a tube are delicate, Rock-n-Roll never forgets. Some anti-rattle ideas that I've tried... Sturdier tubes; $$$ Rubber 1/64" isolation strips between the chassis top and the cabinet's mount points (helped a bit, improved chassis ventilation unexpectedly); Cheap. For a non-combo, buy some nice new mushy rubber feet for the head, or just isolate the head from the cab by putting the head on a non-vibrating surface. Cheap. |
