They are identical to a version of Beovox C40.
Exported to Netherlands only, as far as I know, to be a model number match to Beomaster 2300 (which was UK and Netherlands only).

What Geoff said.
– And some aftermarket stylii are better than others…

A common problem is a bad belt.
Is the motor running?

They are very much standard:

The Stereo indicator should not light up when tuning between stations.
You could have a bad decoder IC.

It will be fine with two pairs of S45.
If you go for Beovox S30, make sure they are type 6301 (the smaller ones).
And get that Beogram repaired. It’s a great deck, and much better looking than anything Technics.

Could be a bad IC (they rarely fail), but you must measure what is being read in at power up to be sure.

Photo 4 is for Beolab 5000.

Bad vol.preset switch. (Contact cleaner + use).
Bad connection to the switch (shorted leads if the old connector type).

Does the display light up ?

I have seen stereo decoder ICs fail in Beomaster 1900. – It’s rare, but it does happen.
However, a failed IC would usually cause complete silence (or slight permanent static), and that’s not what you experience.
Your symptoms (or those of your Beomaster to put it more precise) could point to a
thermal problem, – a capacitor, perhaps – but it could also be something else.

Next time it loses a station, try tuning around and see if the lost station can be found near the original point of tuning, as that could point to a drift problem.

Lubricate motor bearings.
Replace belt.
Clean door tracks.

Martin

Are all electrolytic capacitors in the tuner area reasonably new?
If not, that would be a place to start.

Martin

The center spindle for the cam wheel can be lubricated, but all the small “rattling” arms and levers on the cam wheel should run clean and  dry.
They must NOT be lubricated, or things won’t work.

Martin

[Dillen]

It’s mask programmed by/for B&O.

But these rarely fail.
What are the symptoms?

Martin

[Dillen]

I have seen cases where Beocord 9000 rec. cal ends as Metal tape detected with a CrO2 tape inserted,
if the Beocords bottom plate is not fitted, so correct assembly is one important thing.

Martin

1. Kit here.
2. Yes. And it must be done in an ESD-safe environment.
3. The service manual will tell you how.

Martin

[Dillen]

No. The Marantz post was spam.

Martin

[Dillen]

An open-circuit midrange will see all four going silent.

I have one, refoamed and ready.
PM me if you need.

Martin

[Dillen]

Adjustments can be done through holes in the bottom plate. Refer to the user or service manual.
But trimmers and/or capacitors may be bad.
A service kit is available.
