Another interesting one to restore.

Thanks for the update Gary, and the BVWS Bulletin article on the DAC90A, which as a BVWS member, I did see and read with interest. As you say, the Integra may nor be too complex, and by the mid 30s the basic superhet concept had become stabilised, but still quite a challenge without the circuit or any info. It's certainly stitched you up for a winter project - I can see a Bulletin article in the making:.cool:
