Clear and complete service manual. Easy now to restore my old Kenwood KD-1500.
Thanks a lot.

Thanks for this "hard to find" service manual. This Sony PS212A is a very good turntable that needed to be restored !
 ;
Excellent quality on these manuals. Same as having the original printed manual and incredibly useful when doing a custom install like me. Keep it up on the good work.
;
This is an excellent information source. Great quality and tons of info regarding technical service for the Technics SH8065.
;
5 stars on this manual since it is the complete version, not the half manual you find free for download all over the web. Good job.

ERRORS:
RSA 440:
On all four IC's @PC 1298V), pin 15 and 16 locations are interchanged (rnismarked) on the schematic. On two of the pPC 1298V IC's, (channels one and two only), pins 13 and 11 are connected. Q3,Q28,Q53 and 478 are not the 2N4401 transistor as the schematic im lies, they are an M P S A12 (an NPN Darlington). A static test should show a di e junction from Base to Collector, " + " probe on Base. The input IC U2 on the schematic is labeled LM 833 when actually it is the LM 837N.

Some versions R164 is not used; @ms 2 & 3 on IC 151 are connected by C152). Some versions ZD152 is not used. Some versions R152 is 36KQ (instead of 33K on the schematic). The positive lead for R195 is not connected directly to the positive lead of the as the schematic depicts; instead it is connected to the junction of k%D151.
NOTE: These output transistors are k. equivalent:
