I have come across a reference in Chapter 18 of RDH4 to an article
entitled 'Demagnetizing valves - a cure for residual ripple'

Can anyone throw any light on this? or has anyone tried demagnetizing
valves??

Generally only needed if the flux capacitor has failed.

Does that mean I should demagnetize my DeLorean?

Keeping stray 60Hz magnetic fields away from tubes would be a good idea.
Such fields might have small effects on pre-amp triode's mu, as the
electrons get deflected one way and then another. One usually does this
by keeping power transformers well away from the small signal audio tubes.

Yes.
Be careful of the chrome-plated electric muffler bearings,they're hard
to find anymore. :-p

Do you have the Mr. Fusion upgrade or not?

I do, but he never mentioned a need to demagnetize. I'll just
hop in the car and go back and ask him ....

I bought one from TV huckster Billy Mays, and like everything else he
sells, it doesn't work. At least I got a free "super shammy"
