Depending on what you may be trying to achieve, e.g. non-power amplifier matters, you may get enough information from what is online for Japanese Marantz models , on which these Taiwanese built clones were based. For example, the R1270 model is a budget build of the Marantz 2235. Unfortunately, as Welcome may suggest, full manuals for most of these would come at a price, if available at all.

Its a bit difficult to find something similar.I mean service manuals of r1270 which is of the same family,is quite different.it has double rail while r1220 has single rail.
My problem is that i dont have stereo .there are many stereo stations but i cant get stereo .R-1220 has a A3300 stereo decoder ic.While i test it with a stereo transmitter eveything works.maybe it needs alignment ,may be dry capacitors .the receiver was not used for 40 years!!!
