Fw: [HAM] Re-cap a BV pre?

[Jardini]

My reasoning was that, as I play more notes, the output gets much louder,
so the audio voltage swing is more, so the pre-amp takes more current,
so the power supply caps (which are dried up) can't smooth the power
rail so well, so the hum in the output increases. Where's flaw in my
thinking?

I'm definately not a tube person, so please help me understand this!

If it's not the capacitors in the pre-amp, what do you suppose the problem
could be?

Cheers,
Dave F.
