O.k. this post will be long very long. So please do not quote any of the pictures as I have about a total of 30 in this posting.
Ladies and gents this is the documented exploritative surgery of a origial 1968 custon consle made for a studio called mcginly(sp?) audio studios. As seen from this post

Here we go into the first of many explorations as each time I find something new and sometimes unusual. The brief discription of the console is that it is a 12 tracking recording/mixing console designed to run with a 12 track recorder. Me thinks a scully,stephens as 12 tracks is unusual. it has 12 mic pres, 12 line amps, gotham faders, electrodyne eq's, pan buttons and 2 selectable pan knobs. Aside from L,C,R placement with buttons I can choose to use 2 pan knobs and do real time panning. Anyway here is the bloody details. some questions will follow as I am sctraching my head about a few things...
The night started off like any other night. A cup of coffee and Working on something or other.
last night was working on
and the console attached to it.
First we took off the wood shell to work on the conse. Here we see some shots of back part of the console
What do we see here. Why it's a bunch of UTC input transformers total should be 18 but 2 are missing and currently on order from leeds radio in NYC. I have labeled the trafos as the label is on the bottom and do not wish to remove them just to read it. There are also 2 UTC a-24 output trafos at the end. curious :shock:
We then propped up the main part of the console which has a flip up lid. It has no real way of supporting it but this part of a broom stick did the job. This is the underneith of the main channels section. It was taken before putting up similar stick on the other side.
The the left of that we have the mic pre and line cards. Complete seperate from the rest of the console. All wired together with wire as seen in previous pics. the Mic pres/pre amp cards are the top cards and are martin audio model 114-BC. The first 12 have Beyer tr45 mic trafos attached.
So we pulled a card out to examine.

Another overview shot, See those beyers
Next we see the line amp cards

Very nice....
Moving along got into the gotham faders.
connected with a touchel
And of course the your fader is showing shot
Here we see the bottom of the main out left and right. No stereo fader just 2 mono ones. And what do we see attached the the faders why some more beyer trafos. this time model tr-145
Moving along to the electrodyne eq's. here we see the top. it's a concentric pot. The lower portion has a switch like so
A few have been broken off so we are looking for a replacement. Might go with different concentric pots all together. :grin:
Here we see the edge connector that is attached to each eq.
but with a quick gental pull we get
Now we can remove the eq and place it on a table as seen here.
Remove some screws and we see the inside.
Traces are found here.
The parts are on this side.
Has a trafo or looks like a trafo. on it andf I am thinking that black circular think is the inductor. could be?
And last but not least we have our power supplies
Starting off we have this.
The 3 power supplies connect to it. One end conencts to the console and the other end connects to AC.
This goes to the console
This end goes to AC. Not sure as to how much. The plug says 250V 10 amps / 125 V 15 amps. Could it be a eupropean/ US thing and that depending on which country you would select one? Pulled it apart and nothing on the inside to denote that. Could it be it runs on either or? could it be a 2 phase plug? I'm a lil lost on that one but will figure it out.
and lastly the PSU. 1 of 3 all exactly the same all pulling about 2 amps as denoted by the fuses in front.
Enjoy guys...
