VALVE RATTLE

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.

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. |

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.
