HI, I'm new here and I just aquired a cool device. Its a Grommes / Precision Electronics / Western Electric G5M Tube Mixer. Its a lot like the Altec 1567 Tube mixer but has a lot of important improvements. It has 5 transformer balanced mic inputs, , a line input, tube EQ, and a master gain stage. Basically I want to refresh and modify it. I would like to install DI inputs bypassing the transformer and direct outs for each of the 5 mic channels. It uses both sides of a 12AX7 per channel so I assume there should be sufficient gain for the direct outs. I want to use this as the front end for my DAW. I want the individual outputs for use recording drums and I want to use it as a mixer in its natural state for overdubs, utilising multiple mics into one output. What I'm looking for is any help with this. I could use a schematic if there is one out there. Maybe one of you guys has one of these? How would I go about installing the mods on this? Thanks in advance guys.
Hey Ken,Hi guys, I have a schematic for the above mixer along with a few of them.
reply if you are so inclined.

Hope you don't mind me contacting you this way. Any chance you could email me a copy of that Grommes G5M schematic? My address is : email@example.com
Also, do you happen to know what type of input transformers it takes / WHERE in the world to get them?
Thanks for any advice you could offer, I appreciate your time.
