Channel strip test procedure

[Sturoc]

Would like to know how to go about testing IC based channel strip.
Basically to see if the strip is working 100% as it should and to pinpoint any failing parts that need to be replaced
I have over 24 strips to check and cannot afford sending them out or having a good tech do the work,
Right now they are pulled but can be mounted back in the console's mainframe or tested individually on a bench with an external p/s

Am good with basic parts replacement stuff per soldering but would like to go deeper and learn more.
If anyone can offer a step by step how-to, this would be most appreciated, along with any Test gear suggestions i.e a scope ?

A test signal generator is the very first item you need. A DAW can be used, but having both a sine AND a square wave signal isn't always easily produced with a DAW's basic "test tone" facilities. I prefer a stand-alone generator. I've observed some very competent ProTools or Logic users having to dig around in the menus to find the tone generator and then fiddle with the on-screen controls.

A scope is an essential tool if you want to go any further than "well, that channel seems to be passing some sort of signal..."

Thanks Bri for the quik reply,

Will acquire a test sign gen and keep my eyes out for a good used Scope. About 2/3rds of the channel strips passed a mic signal before i pulled them for inspection and cleaning, the remaining did not or barely. So I will have to go further in testing.
Any tips on that level of testing would be greatly appreciated.

Do you have schematics? If so, please post it..
