Kyocera A-910

1 9 8 5 1985
1 9 8 8 1988

As for the B-910, the A-910 saw two versions but both remained, unlike the two A-710, fairly similar.
All four items share the same CCR ceramic compound chassis and the export A-710 and A-910 are... nearly similar items.

Center of the A-910 is the DIOS layout and SSP (Single-Stage Differential Push-Pull) circuits to do away with the flat amp and connect directly input and output...
- see the diagram below and read the "USER" section for all the circuit details, including diagrams of the EQ and MC stages.

The A-910 was at 95% an export-only item although a few 100V originals have been spotted in Japan.

The latter weren't as different from their export versions as the A-710 were from the export A-710 but did show a few visual differences :
wood sideburns replaced by thinner anodized aluminium sides (like on the other 900s), champagne top & back plates and black front scripting vs. the white of the export versions.
The export version is much prettier.

Mostly, guts-wise, if the doubled-up third speaker terminals ("direct" speakers) do exist on the japanese original, they are't doubled-up : no banana terminals there but a single set of regular binding posts.

I've yet to find a single image of this A-910 original in any of my japanese literature - magazines included ; Kyocera sadly didn't sell many outside Japan either.

Probably one of the best and best-sounding 1980s integrated amplifiers.
