Yes I can't connect a new one as though it is a replacement because of the ribbon connections, so need to know whether I can connect it as though it is an external; vcr, record player, tv etc using just the two analogue inputs of these at the back of the tuner. Presumably these then go into the amp and out to the speakers. A few players I've looked at have an optical fibre connection out and two analogue out, so presumably you can use either if these and don't have to use both.
Yes, any of the analogue inputs (apart from phono) will accept a CD player if it comes to you doing that.
The optical out is just another method of connection for amps/dacs/minidisc recorders etc that can accept optical.

The trim pot is located on the laser pickup. It needs a degree-turn clockwise for a tiny increase in laser power. You may need to turn it few degrees clockwise.
The CD's bought in shops vary vastly in reflectivity.
With time, the laser power output will drop a little. This is normal and expected. There is absolutely no harm in increasing that power a bit, to bring it back to a required level. It is ludicrous not to try to increase the laser power if you are going to replace the laser pickup, or even worse - the whole mechanism, just because the laser output dropped a little. What is there to lose? From my experience, and from the feedback I get from my friends (customers), the mechanisms I adjusted are all still going strong. None has failed completely so far, but few have come back for re-adjustment. We are talking 5 years' intervals or greater.
The mechanisms you buy (brand new) ALSO require a proper laser power adjustment. Most of the time, they arrive with the laser output that is insufficient for a low reflectivity CD's to play properly. So, many people go and buy a second mechanism and then experience the same "problem". By the time they install the second mechanism, the flexible ribbon cables are usually damaged beyond repair - and then the CD players are chucked in rubbish. Amazing but true.
The RF pattern pp value tolerance is very large (0.6V) - see the pdf I attached. In other words, the laser pickup manufacturers know about large tolerance in CD's reflectivity - hence the almost 50% tolerance in RF pattern amplitude for such a "little" pp value (only 1.5V pp).

Okay, thanks, so will attempt slight adjustment of laser power as really have nothing to lose.
I had reply from seller about skipping "I'm not prepared to say that it will work perfectly because when I tested it I found it to skip when tapped on the lid or if the bench it was tested on was knocked. I know from experience that this shouldn't happen. I can't really say anymore than that."
My first thought is it'll be fine if I don't knock where it is. But any thoughts about whether this is serious?

Any old player will skip at some point when subject to mechanical shock. Does he mean dropping a feather onto it causes problems, or that it needs a good whack.
'Old player' here refers to one that reads the disc in real time, not one that reads ahead and stores the data in memory... those types can have multiple attempts to correct missed data.

In really a really low number of cases turning the pot on technics mechanism had helped me, most of the cases is a failing motor, capacitor, or filth inside the optics (once even cleaned a spider nest on a technics lens)... still in case of death of the mechanism you can scavenge from almost any panasonic boombox from the same time, i pressume your mechanism is RAE110 113 or 150, all of them common in technics SL-PG series (non A since they are philips) RAE 110 and 113 are even pin compatible and since they seem diffrent are electronically compatible
