Magnavox Rat Rod, Part Deux

I picked up another Magnavox amplifier a while back, and finally have had time to get it on the bench and look it over.  This one is model 8301 stereo single ended amp with EL84/6BQ5 outputs, each driven by individual triode sections of a single 6EU7 preamp tube.  Rectification is via a 6CA4 full wave rectifier.  All the glass checked out good, and I am in the process of slowly bringing it up on a variac.  The schematic indicates that the front end is setup with passive RIAA equalization, and the balance control just attenuates feedback on the channel that you are balancing toward.  My first instinct is to just rip the whole mess out, but I will give it a listen before doing anything drastic.
