Here it is. She's a beauty. Contact me if you need one. It should be available in a few weeks. Fully tested and plug and play.

I've been searching on line for DM48 chips for weeks... finally happened across this thread. I think this is still the only solution? It's 10 years later, you'd think there'd be options.

Check with S&M Electro-Tech aka Turnswitch.

They were super nice and sent me a used module.

The owner passed away last year. I think they still sell speakers but have passed on the repair operations to someone near the the repair facility.

Oh that is unfortunate sad news. If it was Greg, he was an exceptional person and I'm sure will be missed by all he helped.

Hey j69shep,
I’m new to this forum. Been working on Delco radios for 15 years. Self taught in repairing the Delco 2700 and 2000 series. Every now and then I run across a part not being reproduced. This DM48 module is a hard one to find. I sure can appreciate some reverse engineering and someone taking the time to map this one out.
Any chance of getting a couple of these completed DM-48 modules? I’ve been working on a ‘75 Delco Stereo. I am sure I have a bad one.
