I’d like to start by saying I mean all of the following review in to politest and most constructive way I can. I take responsibility for my purchase - I read the disclaimers, paid my fifteen bucks, bought the ticket, and took the ride. This is not - capital NOT - a review of turntableneedles.com nor the myriad other products and services they provide. That said:
Please, do yourself a favor and try to find the official Superscope/Marantz service manual. This one, while an interesting artifact of a simpler time, is just a pretty good scan of a “Photofact” third-party service manual. I mean, it’s neat that they (the Photofact engineers) went through all the trouble of reverse-engineering the circuit to draw their own unique version of the schematic, and the sub assemblies are well photographed and with pads labeled logically according to the rather unique Photofact system, but the photos are all in black and white and with few exceptions there is no way to verify the most basic premise of a service manual i.e. what is physically connected to what. With modest effort you should be able to, say, follow the circuit of the main board, but god help you if you wish to decode, say, how the input jack board is physically connected to the main board. You may substitute any other two assemblies into the previous statement and it would still hold true, and believe me, I tested it.
Perhaps I am spoiled by a career of only dealing with clear, concise, and correct manufactures’ service manuals, or perhaps I am not as clever as I think I am. Personally, I think a little of both is true. Still, my overwhelming feeling after purchasing and attempting to use this manual to repair a thoroughly modified/hacked C-105 is that I would have been better off shelving it until I found an official service manual.
But hey, who am I anyway and really, what do I know?
