We don't talk much about repairing or upgrading solid state gear such as the Marantz 2270 and the Pioneer SX-850 and other solid state gear of a similar nature..Believe it or not,they have similar problems that their tube cousins have and that is, capacitors whether they be coupling or bypass.
The biggest culprits in solid state gear are the 1 uf and the 2.2uf, and the 4.7uf, and the 16uf, and the 47uf caps..If you have weak volume in one channel or the other whether it be the phono stage or line stage,chances are its a cap of one of those values causing the problem..The 1uf caps are typically input couplers and they open or get severely leaky and can cause weak output.
It helps to have a schematic and having an oscilloscope is an added plus.
