IF the machine was truly working as sold to you, then it sounds like your service engineer might have just turned it into a basket case. Sure, some of the Frako caps used in the Studer power supplies were flaky, but changing vast amounts of components before even turning the thing on is just criminal. Yes, some of the components might be out of spec after 40 years plus, but that doesn't mean that you need a mass rebuild. Studer were really OCD in matching components, when assembling the boards. If the components have all drifted a little over time, it probably doesn't matter.
When I bought my first Sony APR 5002, it pulled tape and it played. It wasn't great, but it "worked". All I needed was the heads relapping, a new battery to save the software settings, lubricating the motors and a line up. My Studer A807/II hasn't had a single thing replaced. My newer Sony APR 5003 hasn't had as single thing done, apart from a tape line up. It is absolutely on the money in terms of line up. These are all 30 year old machines.
Now I apologise if I have got it wrong and if I have maligned a competent engineer, but I would be distraught, if I was in your shoes. I hope you get a solution, but maybe some of the others can make some sensible suggestions.
