I saw that last night....I think the real jewel is that fixed filter bank.

Yeah, that 907 FFB is a classic. Sometimes I'll run the Minimoog through it, and it gets some of those Moog modular tones. No one has really made a clone of these with the torridial coils. A big part of that unique sound.
May be I should wind my own?

torridial coils. A big part of that unique sound.

I agree very much.

I used to work on guitar amps every so often and was surprised to find that some Mesa Boogie amps used coil based EQs.
I thought they sounded great in those amps and also in the Moog 907 and 914 modules.
Pity that this technology has been so overlooked in later years in favor of opamp based designs.

Well thats also one of the more expensive modules....so if its under a grand then they probably got a good buy on it....especially if they get it for under 800 Id say.

Learning about those coils...I think I understand why modusonics was charging 1885 for the 907a and 2850 foro the 914

I thought it was interesting to see the H shaped frames on either side of the panel on the rear shots. I figured it would be in a box back there.

FWIW they wanted 4200 for the 960, 1185 for the interface, and 675 for the seq switch. These are the Apr 07 prices

I wonder who the initials on the sticker belong to. Mechanically that filter seems too fragile for a portable synth. So far it is at $400. Good price but way to limited use module for me to bid on it. (I'll just continue to use my active 1/3 octave eq's in the 907's place.)

I've always wondered where this seller gets his mind altering substances. His prices are always pure drug induced fantasy. And it is all incomplete, broken or otherwise damaged.

Well it is just my opinion here....
I think perhaps the seller of the modules is thinking that he can get more money if he broke his system apart.
For instance, he took out the filter bank, the envelope gen, the osc driver and osc and left the cp panels on the case....which he sold seperately. I think he doesn't realize those cp panels were pretty expensive back in the day too and are pretty valuable....perhaps not as much as a 904 but its definately in the system for a reason.

I think he shoudl have just sold the whole system. Notice he hasn't listed the 904, or the VCA's or else they are already sold. I think theres a 921 too that would get some $.

One of those tags was initialed KL. I wonder whom that might be...

Kevin Lightner · Post by **Kevin Lightner** » Sun Sep 20, 2009 7:49 pm

The KL isn't me.
It's often seen on Moog products I see though.

A few other things....

Some production tags are long and haven't been torn off.
They were normally torn off as they went through the various stages of production and testing.
Since some tags are still complete, I'd guess these came from the last days of Moog when production stopped.
Just a guess, but rare to see tags like that either way.

As for selling it all complete in the case, I'm not certain that would be the best idea.
Model 15s came with 921s, not 901s.
901Bs require a -10 volt supply.
The 909 power supply normally found in model 15 doesn't provide this voltage.
So it's probably best to sell everything individually.

I don't know who the tech is that worked on these modules.
I don't think it was me.
At least one module has had its selector switch replaced with a type different than stock.
I have the original switches and would have used one.
I'm also wondering if the tech actually spec'd the capacitors correctly.
These are the ones towards the front in a row on the 901Bs.
They have to be very precisely chosen and matched to the other 901s because they select the octave settings.
In stock Moogs, you'll often see two or three caps paralleled in order to achieve this precision.
While the pics aren't very good and I might be missing something, it doesn't appear the caps used were spec'd in this same way.
Perhaps the tech got lucky or perhaps they didn't know what they were doing.
But how well they switch octaves will be up for the new owner to find out.
Hopefully they all work as they should.
They're gonna sell for a lot.

so, the auction ended and the VCO's and controller and EG went for the expected high price but . . . what happened to the 907 FFB????! I can't find it in the completed auctions!

Sheesh, never mind!

It doesn't end for almost a couple days!

The seller only got $12,356.00 for the 907 FFB.
Time to start rolling my own torridial coils.
What should I charge for a set?
Lets see...20 coils for the 907, and 28 coils for 914. Thats quite a bit of winding.

O M FREAKIN G!!!!!!!!!!!!!!!!!

I thought it was the coolest part of the lot but figured it would go for $1000 to $1500 or so at most . . . .shows how much I know about it!

I must (reluctantly) concur, that price is crazy. I have an old IIP with the earlier 907A (3 space) FFB. Better get my insurance guy on the phone...

Here you go...

I put the Minimoog plack on the power supply panel in the late 70s because people kept coming up to me at gigs asking "is that a Minimoog?"

Many of these modules date from the late 60s. I believe it may have one of the early propotype envelope followers. The grey dyno-lables were there when I got it and it has Dr. Robert's name on the SN card as do a few of the other modules. The switch on the 901 is a 50K tone which Sound Arts used to sync to film. Note the 3U 907A in the upper left cabinet. The 901B saw outputs are normaled to the mixers and the output of the left mixer is normaled to the #4 input of the right one. Except for the single blank I made into a 2x switch in 75, its exactly as I got it in 1974.
