Too much plate filtering in modern amps makes them sound stiff ?

[diagrammatiks]

ya. class A and all the looseness that implies...

it's 33 watts running 2 6l6s in class A. 70uf is more then adequate.

...its like trying to sound like BBKing with EMGs...

I bet BB King would sound just like BB King with EMGs.

hah considering that actives and high output pickups were first used by jazz guitarists in hollowbodies and archtops...

bb king would probably sound more bb king.

probably had actives of some sort already.

Yes, I bet BB King would sound just like BB King with EMGs.

But I don't think BB King with EMGs would sound just like BB King.

Stiff filtering is great for stack-cabinet (or any other infinite baffle cab) amps with solid-state rectfiers (most Marshalls come to mind) for the trademark "thump" you get when driving it hard. That's the sound of the filters keeping up with the demand, and as was stated, you WANT the low-end nice and tight in those situations. However, there IS room for experimentation. The only problem is, if you go to high with filtering, the amp can motorboat. Too low, and the amp might hum and become unstable due to insufficient power supply decoupling between stages.

Tube rectfiers can't handle excessive filtering and must be approached differently.

Hey check the gut shot of a Carr Vincent on p3 of this GP article
http://www.carramps.com/press/gp_200712.pdf
its using PP film Solen caps in the PS with maybe 70 TOTAL uF of filtering!!!? Expensive AND loose!

And wired like it was made in a school shop class.

It's important to remember that **any** difference from "vintage" amps will be d@mned by some amp maker as blasphemy. Only the variations *they* think make their amps more like the singing of angels will be the Righteous, Moral, and Deity Approved changes that are not only great sounding, but still "vintage", whatever that means to them, in the spirit of William Jefferson Clinton's comment that "...it all depends on what your definition of "is" is."

Yikes!!!

I don't care WHO made the amp or what it cost, that is a shitty layout and wiring job.

That's a new one on me, motorboating generally being due to bad B+ cap in a proven design, or excessive gain and insufficient B+ decoupling on a design project.
How does a large value B+ cap cause motorboating?

Curious too. Fixing motorboating amps used to be a matter of changing one bad reservoir cap(for the same size) in most cases I saw.
