Hi
i havent read the whole topic yet but i know the answer to your 5010
"buzzing background" sound...
this is NORMAL behaviour on the 5010.

What you hear is the Ampsound with gain on 10 as a low volume
background noise.
It is a lets call it "design flaw".

The 5010 is only put to good use with the gain on "10" forget it for cleans and
use it like youre supposed to as a "practice 2203" .

I recall that the background fizz at low gain settings is not all that noticable
at higher volumes...so try the Amp with the Master volume turned at least to 6
and forget about playing totally clean gain has to be at 7 for some hendrixy tones.

Good Luck...the 5010 is a good sounding SS Marshall if used properly
for 80s Hardrock played with a higher output Humbucker.

(all IMO)

(a lot of the 5010s have a problem with oscillations at high gain settings,
i have seen so many with this problem that i think its a design flaw too.
Marshall changed a lot of stuff in their solid state amps of the 80s, lots
of revisions.

The huge gain problem is less a design flaw than it is people trying to improve the amp.  In that 5000 series of amps, you might see 1458 op amp.  I recommend getting exactly that to replace them.  people "upgrade" to 4558, 4560. 4580, and then their amps become unstable at gain.

Stick with the 1458 there.

1458 is a dual 741. Appaling specs. That's why it works so well with high gain guitar settings. But if you want your amp cleaner, you'd have to upgrade them to 4558s or better, and work on the compensation caps and feedback.

Tubes suck!

I don't want clean AT ALL on my Marshall, i just want it to sound like a Marshall instead of a cheap practice amp! My old Lead20 sounded great-it just could't be heard over a drummer. It had a sweet sound, wheareas this particular 5010 ( and perhaps the Red McKenzie version in general) sounds like a turd smells. The later versions with the horizontal and single inputs sound really good, and I don't know why mine doesn't- but it really doesn't.

I had the 5275; Mosfet 100; Lead 12, Artist 3203 , Marshall 5010, Valvestate 100, JCM 900 Dual Reverb...sorry to say this but good Marshall is not happening with any of those...cut the chase and get real.

(1959 2203 2210 JTM45)x(PPIMV and or Attenuator)=ROCK

Could very well be that your 5010 has a transitional circuit from the
earlier Marshall SS Amps, and i can imagine that sounding not pleasant.

The mid 80s 5010 do a generic
ACDC Sound, nothing more or less.
