It's odd that there are some Philips Mustard caps in there which look original.
Must have been right on the cusp of going from paper caps to poly caps.
I've never encountered a crook mustard in all my years of repairing radio's and TV's.
Has anyone else?

Great thankyou everyone, ill get to it! Any suggestions on sourcing the replacement caps/resistors? I generally use RSonline or Jaycar, occasionally eBay.

There's Tallar Carl on this forum - he has caps.

Philips "mustard" polyesters are gold.

When they were first released you could only get them in 160v and 400v ratings, probably explains the 600v paper caps The other two are in low voltage not-so-critical places.

Kriesler was trying to design paper caps out of their products for years. I have a 1959 TV chassis with lots of original (then quite expensive) Styro caps.

I get a lot of that sort of thing from WES components

That particular type of cream cap should also be visually inspected. I have seen more than one with a cracked jacket, mainly on the ends.

Not trust a Philips Mustard? What are you saying Marc?!!!

In my TV service career I would have come across MILLIONS of these caps. Yes, millions. The only bad ones I've ever seen is where a lead has been forcibly pulled from an end!!

I've seen mustards with soldering iron scars and heat damage from adjacent power resistors, still working as they should.

If a lead wire is bent too close to the end it can crack the epoxy around the taper point. I've seen that. But the cap itself was fine in every case. They are not hygroscopic, that's the difference. You could actually remove the mustard coating (if it were possible) and the cap would not go leaky.

If you try to use a 400v mustard in a place that calls for a 1kV cap (as I've seen done), it will fail short circuit. As you would expect!

My only beef with Philips Mustards is, like all polyester film caps, they have a temperature characteristic. So if you were to use one in a TV horizontal oscillator to replace a Styro (because Ducon Styroseals and others with the same construction can go intermittent O/C from cold) the oscillator will drift in frequency as the TV warms up. That's not leakage, it's change in capacitance. Most plastic and ceramic caps do this.

I have not seen any evidence after nearly 60 years that they have a lifetime. In other words, I've seen no age-related failures.

Thanks again for the info, I'm looking into obtaining the replacement caps.

Embarrassingly due to a momentary lapse of attention I snapped the tonearm when closing the lid.
Does anybody know where I would find such a thing? Ive not turned anything up on google as yet.

Here are your caps:

Thanks Ian ill start with those!

My only issue with the polyester "Mustard cap" is mechanical issues they should be wired in such a fashion that the wires are not subject to tension: Tension seems to break them, that's why one visually inspects them for cracking.

A problem seen and therefore, one to be noted.

With all my service experience(as a full time, permanent vocation I might add), Philips mustard caps are both physically and electrically the most reliable cap ever.
I could count on one hand the number of faulty/damaged mustard caps after checking/testing hundred of thousands of these!
Fake news!

You have the 11-98A which should have a BSR UA25 record changer. The earlier 11-98 used a BSR UA15, but the radiogram unit is otherwise identical.

I had a look around in my box of bits but couldn't find anything. You may have to hunt around for a wreck as a donor for the tone arm. Just make sure your changer is indeed a UA25. That said lot of BSR parts are interchangeable from different models.

Any chance of gluing it back together?

Don't know about fake news. I was fixing before they were even on the market. Many on the forum would not be aware that they can crack, if installed badly & I found(as one example) several cracked in a car radio and there have been others. These are not the only ones that exhibit this there were at least two early "Mud" types that cracked & there are some versions of axial caps about 3/8" by 1/2" long, often found in early transistor stuff that crack, or are just as bad as wax paper & you need to toss all of them.

You see a lot of radios in 50 years.

Even more in 60 years, .
I reckon that if you hit those mustard caps with a hammer and then pealed off the covering, they would still work.
They are almost like a styro cap inside.
