Dating that Pioneer
August 78(YH), made for the USA market (KU) I have the correct list for dating. . . Basically all Pioneers from 70-85 are 1 year older than was thought.
YH= 1978-Aug now before KU meant Aug 79. . .
KU = For US market
BTW thats a nice 780. . .
Remember this;
Here is just a sampling of info about SX-780's from the 3rd Edition Spec Bible. It's not even the regular specs information area, just some partial footnotes from one page.

SX-590, SX-690, SX-790, and SX-890 are SX-580, SX-680, SX-780, & SX-880, respectively, with a black dial scale, rather than silver, & were available in two versions: HG and KU
