M100 Rev. Question

[Shinju]

What rev is this M100 all the ones I have ever owned and seen have had the gold exposed trace boards.

This one looks the same but with different resisters near the torrid and green board coating.

And I will need a new speaker/power terminal if any of you have some extra's laying around let me know! These are pretty beat up!

My current M100



M100 that I am used to seeing (taken from ampguts)

The bottom pic is 1 of my my M100's I believe, Eric modded it like that the originals have 6 caps. I have a brand new speaker terminal here it's black though. You could dye your power terminal black to match.

first few hundred were green boards....both mine are all green...my outlaw is gold though

Veleks can tell you the revisions

[marko]

doesn't really matter how many caps go in there as long as there's enough capacitance to do the job, could of used 2x 6800uf caps and job done. purists will like to see 6 caps but who cares when the lid is on?

rev should be indicated here under power terminal IIRC

[Shinju]

Matt, I looked in that spot there is not a Rev number stamped under the term.

Not a super.big deal just curious if someone had an idea on when this one was built.

it was within the first few hundred built from what I was told..

I have 7 M100's and every one of them the rev version is where Matt circled right under the torroid just in front of the metal bracket that the power terminal screws onto.
The last one of mine I looked at is a REV A and has the gold plated board, like all my others so maybe just the gold plated boards have the REV version there.

Nothing wrong with this green board this is one of the first 200-300 boards. Green boards were built here in the USA and gold board in Taiwan. Who put two caps instead of six on that gold plated amplifier? That was a bad idea better to have six smaller caps.

Eric did that I have since changed it back to 6 caps.

I have driven 1 of my m100's(bought it new myself) like a race car in the red since early 90's ....only problem has been the rca jacket came off....is one board better than the other? green boards didnt have any rev's done to them I would think? Do you update the green board m100's to the same as the glod plated boards?

i just guessing but it seems to me that if that's the very first run of that amp then maybe it would'nt have a board rev letter on it because think about it if it's the first of that amp, then what can they revise it from the design table or what?
