API 328 or 314D

[conleycd]

Hey people,

I've been toying with a handful of ideas but rather than reinvent the wheel I'm wondering if anyone has access to some of vintage API circuit schematics. 

I'm looking for a 328 card and/or 314D.  Both are a mean to provide balanced audio distribution.  I have the datasheets from Dan Alexander audio which shows a block diagram.  If I was more of a designer and less of a technician (in the loosest sense of the word) I would be able to figure the additional components myself - but I'm not.

Any assistance would be great.  Thanks.

not sure if this is exactly what you are looking for, but it might give you some ideas: http://classicapi.com/catalog/product_info.php?cPath=22&products_id=55 - active inverting summing amplifier.
jeff at classic audio of illinois is great and he might be able to help you figure what you're looking to achieve.  hope this helps.
kind regards,
grant

Yup I know of the active inverting summing pcb from classicapi - no doubt useful.  These two products that I'm looking for are the exact opposite to the ACA.  They take a single signal and split it to many outputs.

Thanks though.

I finally found some info on the 328. I've uploaded it to the GroupDiy account.

I'm probably dense - what's the GroupDIY account?  How do I access it?  Thanks.
