I have managed to get hold of a DPK750E, it has a reticon chip for brains, identical controls to the 750F.

The internal feedback is not up to much. Running it back on itself however is very nice. Will do some cleaning to it, and then take some pix.

More info on Reticon and BBD devices

This delay is in a 70mm deep, 3ru high box, kinda LA2A size.

it has two Reticon chips inside it, both SAD1024 7573

that last bit, 7573 might be a date code?

I have not measured the delay time yet, it might be that only half of each chip is being used.

the chips are socketed, its nicely constructed and wired with care.

I found an advert for Reticon in Popular Elrctronics from 1976

the board appears to be factory fresh, no signs of work on it.
