Very nice – but please keep in mind, that the muting system needs to be changed accordingly,
as the models with RIAA mutes before the RIAA rather than after.
And not all type 59xx decks has the output from the power supply to the RIAA module.

That’s because speaker set 1 is meant for local use – in the same room as the Beocenter.
Speaker set 2 is typically routed to linked systems in other rooms, where they are muted locally – and independantly.

All Beovox S45 have Philips tweeters.

Yours should have the AD 0163 T8 with black dome.

Why not an original part?

Here.

If you have a moment for me to learn, why this recommendation?

Sure.
An emitter-base voltage difference of several volts on a PNP transistor points to a missing B_E connection.
Similarly, the exact same voltages found on base and collector could point to an internal short here.

Missing blinding plug at the rear socket panel?

My Playmaker let out the magic dmoke one day. Turned out it was one of the filter caps in the power supply that exploded It smelled a lot like smoke and the smell was not gone before a week. I can still smell something inside it. Today I replaced both filter caps snd it looks like it is running again

They are suppressor caps.
They MUST be Class X2 types – nothing else!

Lots of potential problems in that photo. Black Roederstein capacitors, old trimmers etc.
Grab a service kit and have it refurbished.

Martin

Wrong setting of muting level, perhaps.
Try without Silent Tuning (AFC/ST off).

Martin

[Dillen]

Possible, but not always easy.
It’s welcome here for repair.  PM me.

Martin

[Dillen]

Oxidated microswitch, perhaps.

Get the proper parts.

If these measurements were taken on 0TR1, replace it!

Martin

[Dillen]

Price and location, please?

Martin

[Dillen]

Also – replace capacitors in the processor module.

Martin

[Dillen]

What brand and type of capacitor did you fit for C2103?
Did you do any adjustments? – If not DON’T do any.

Drive supports here.
No, you cannot 3D-print these. There are more to them than meets the eye.

Perhaps that missing up and down movement is the key.

Martin

0TR1 provides a good 15V, yes.
But does it close completely in standby?

Martin

[Dillen]

If the platter spins in standby check 0TR1 (TIP32A).
I have seen more than one case of it being bad, not closing the 15V down but instead leaving it hovering around 5-6V.

And check copper traces in the -15V regulator area.
The traces are known to develop cracks near solder pads, that can be very difficult to spot. Particularly if your soldering iron is a bit too hot.

Clean the stylus carefully.
