subside completely, you are left with this
background crackle and if you leave the set
off for a few days it gets worse again

Years ago on rec.antique.r+p there was a thrad on "Thunderstorms" -- that's
where the crackles build up to big static crashes and rumbles. The consensus
was leaky capacitors, specifically the paper dielectric types.

But I wouldn't doubt resistors could do it too -- in fact, ISTR finding one
such by tapping around. Of course loose tube sockets are the No. 1 cause, and
switch contacts. Keep that DeoxIt handy. --Mike K.
