Sunair Radio

Sunair is very good radio.
My friend has got model GRC-970 from year 1970/1980.

It however is missing two cards.
One DA-converter card and one AGC card.

He has got from factory the radio manual, which has circuit diagrams of both the cards.

Well, I got job to make the circuits again.

I manufactured these cards December 2015.
