So what's with these Heavy Metal bands where they
are still using a Tube guitar amp...

*Tube* guitar amps are supposed to sound better.

They generally do. They introduce concordant (even order) harmonic
distortion, so are nicer to listen to.

My old *tube* receivers still work fine even though they're antiques
(and quite obsolete). But in serious QRM/QRN I have to switch to my
modern rig with the receiver digital processing if I want to complete
the QSO.

My valve (tube - U.S.) receivers far out-perform /any/ semiconductor
receiver. I don't need any digital processing at all.

We who know better - That Morse Code is useless.

CW is *not* useless. It's fun.

I can "work the world" on tiny power using CW, whereas I'd have to use
stupid amounts of power to get similar results with SSB. Also, the people
you meet on CW tend to be much more friendly!
