Uploaded the MAK-6581 service manual to
Filebin :: bin ackfoky2r92knbty, the link will last a week...
Also put it up on elektrotanya.com but it might take a while to be sorted and findable?

Thanks for making it available. The notch filter looks really similar to the HP8903/Boonton 1120. The overall performance should be quite good and a few opamp improvements could make for a significant performance improvement. Well worth making the effort.
The GPIB looks very manageable. The program I have started: PC Software control for Analog Audio Analyzers Releases * 1audio/Boonton-Windows-10 * GitHub could be modified to control this pretty easily.

The mods are described starting from page 21
ShibaSoku Automatic Distortion Analyzer
Are there any other?
Contacted various companies in Japan known to be affiliated with ShibaSoku, and seems there is no Service Manual for the 725C.
However I got the user manual, which is nice and polished.
Meh, too large to attach here

Hi 1audio, can you share the service manual and modification method package to me? I just purchase one 725D want to try to upgrade it. thanksI made scans of the manual and have shared them with anyone who has asked. They are too big to post here. Those are what I sent you.
Maybe post on BAMA or one of the other similar sites.
