You win some, you lose some. I had to scrap a HP 54602B scope a while ago. Don’t give up yet though. From even the worst turds we gain experience, even if it results in a few grey hairs too :-+
Philips are one of those strange companies. The electrical designs are very very good but the mechanical designs are designed by the electrical engineers I’m sure because they’re rubbish. Oh we’ll just stick the current shunt between some bits of plastic on the front panel. Oh the front panel has melted (been there).

Spend £3 on a ebay tally counter, the mechanical kind. Saves on the "Was that 40 turns or 50 turns I just finished?" moments. You can just 'click' turns as you go or if the turns require two hands, do them in fives and then hit the tally counter 5 times.
After you buy it, put it somewhere logical, not "somewhere sensible" or you'll never find it when you need it. Perhaps in the same drawer/box as your collection of cores or spools of magnet wire. (i.e. I haven't a clue where mine is at the moment.)

I have some Hengstler counters (electronic). Should be easy to rig up something involving a foot switch, so you have both hands free and can see the count nicely.
And then there was this Meteor winding machine that went into the trash. I guess bd139 would have loved it (if he had the space to put it). Nobody wanted it, not even me (just too f*ing big).

I don't give up easily! Not on this one! While there are very few special parts (like the "Photochopper" and that fuse resistor), lots of the ordinary parts aren't easy to come by today. I have thousands of TTL ICs, but only a few of those used in this instrument. And they can't be bought any more. :(
Failure is not an option. But a likely outcome ...

If you fall into a hole where you can't find parts......ask here !
Many of us have old IC's and especially in my junk pile of old PCB's 1m2 x 500mm high.....dozens and dozens of old IC's.
A good few tubes of new assorted stuff too.

Yep I’ve got TTL coming out of my ears that I skip dived off an old employer.
Disclaimer: I sold all the good stuff on eBay already (74181s etc) :D
