ADM Schmatics/Wiring Diagrams

Has anyone found a resource for these schematics? Im looking for an eq labelled 1530-001 on a stick on label and an input module labelled M1920
thanks

I have got a couple of tatty monitor modules - with some parts missing
£3 plus postage!!!
See Brewery for more details

Hi.

I should have the schematics for the 1540 eq and the pre amp as well.
Have to check, if i have them in scanned form i can post them.
If only in paper it will have to be a few weeks before i could get them up.

Thanks API!

Hi again.

Could not find the schematic or the pinout on this computer.
But i did find the original brochure for the 1540 eq!
Give me a few weeks, am going away on monday, and i will try to find it.
But please remind me!

I'm also looking for schematics for my Mic Pre module and EQ module,
although I dont know the model numbers for these modules

does anyone know what models could these be?

thanks

re the cylindrical transformer,
ADM often used the UTC O-8.

So this 2787 marked transformer could be an UTC O-8?

UTC O-8 is a vacuum tube output transformer, not likely to be in ADM gear unless they were using it in some novel way.  O-12 makes perfect sense.

portion of the ADM 780 input module attached.

The UTC O-8  makes a great step-up Input Transformers,  wired in 'reverse': a fairly common practice.

That is indeed what they are doing, but I am surprised they would want a 15k secondary for an opamp input.

I have both an O-8 and an O-12 on my shelf if Whoops wants some DCR measurements of the windings to compare with the "2787"

Thanks, I will let you know if I need that.

For now I would just like to know the model numbers or any info on the modules I have, if any of you could help.

I searched as much as i could on the web but couldn't find any info on these particular modules.

Thanks

I have all the documents and lots of good mods. [email protected]
both those units can sound incredible and I have seen them make plenty
of killer records! N
