Very useful Service Manual! With it I was able to identify the damaged pots in my old amplifier, purchase the adequate replacements and make myself the repair.
I have again my old amplifier, still a very good one that I will keep for as many years as I can!
Thanks to Owner Manuals!

Good price for the manual and easy to locate on the site and download. Plus, just like the original. Thanks a lot.

Genuine Service Manual. Link was available in less then an hour or so. Service Manual contains assembly, PCB layout, complete circuit diagram, Components list etc

Great and very well scanned Service Manual, also very fast download - Recomended !

I'm quite impressed. I had to wait 24 hours for my manual (quite a rare one) but I got it and the quality was good. Also, from trawling the web, these prices are by far the best.

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:
