Well, that's quite a bit different from what I would imagine it would look like, using inductors for the mids.
Might be an interesting build, but I'm having way too much fun with filterpreamps right now!
Regards,
Jarno.

This 2001 circuit is either later NTMB or NTMB-918.
AFAIK, the the difference between the NTMB or NTMB-918 is some cap voltages, the docs are pretty much the same anyway.

I just did the layout of the modded one in eagle and will get a proto-layout tonight or tomorrow.
I am making this a 2 battery unit. Like the NTSMB-18 units. Im also going to add a switch for mid freq's.
What I dont know, is what value inductors to use. I guess I could steal from ampeg and mesa.

Inductors are 150mH each!I've built the vero but have difficulties finding those inductors! Does anyone can direct me me to a source where to buy them! Thanks in advance!

ohh...cause Im a dork.
I save all little or big changes as a new schematic / board layout.
the board layout on that sucks....I have no clue as to a good layout.
