ModeratorVery nice indeed.
For shipping considerations, it would also be good to know where you ship from.Martin
Dillen
ModeratorDepends on the type of Beovox 3702.
Kits are readily available:

ModeratorIt’s a known problem with this drive type.
Glue in a small piece of carton or plastic card (apprx 0,5 mm thickness) here:You can give the exposed motor bearing a tiny drop of sinter oil.
The belt for the motor must NOT be tight!Martin
Dillen
ModeratorIt’s not uncommon to see the Beocords rubber feet missing as they harden with age.
The outer parts break off, while the inner parts fall inwards where they will often
get stuck between the Beocords bottom plate and the drawer, causing a braking effect.
Look in from the front with a torch light.Martin

ModeratorDifficult to diagnose from a distance, but I have seen aftermarket cables with
wrong pin configurations.Martin
Dillen
ModeratorCheck continuity in the cables.

ModeratorWhich cartridge are you using?
And what is the tracking force set to?Martin
Dillen
ModeratorSolenoid leads touching the platter underside?
Martin
Dillen
ModeratorIt’s cast metal.
It can come out if you heat it carefully, not melting the plastic, only softening the glue.Martin
Dillen
ModeratorNot sure what you mean?
VTVM usually refers to a Vacuum Tube Volt Meter (F.e. Bang & Olufsen RV9/RV11 etc.,
but today most digital meters have a suitable high impedance so will work fine for most readings of this type.Martin
Dillen
ModeratorDont’ use readouts of old and bad components for reference!
Set the new trimmer in its center position, fit it and refer to the servicemanual for
the corresponding measuring points and correct settings.Martin
Dillen
ModeratorDid you try what I suggested?
Martin
Dillen
ModeratorDoes the white bar at the back tumble when lifting/lowering?
Martin
Dillen
ModeratorIs it in play state?
If so, it looks right, considering the heavily set tracking force.Martin
Dillen
ModeratorService kit etc. here.
And it looks a very nice project.
They are definitely worth it.Well spotted, that break!

ModeratorI have seen cases, where too much friction between the metal arm on the microswitch and the actuator arm that rubs against it inside the contact housing kept it from activating.
Clean the parts and add a little teflon oil to lower the friction.And, as mentioned above, the deck will not work correctly upside down, which makes
it a little tricky to diagnose and test.Martin
Dillen
ModeratorIt may be a little oxidation on the contacts, – it could wear away in daily use.

ModeratorThe stereo light should only come on when receiving a stereo station.
Are you sure it’s actually playing stereo? Could be a tuner/MPX decoder problem.Martin
Dillen
ModeratorBeolab 4000 will never be 100% quiet.
It’s more or less in the nature of active speakers. Keep in mind that they
are on max volume constantly and will amplify every bit of noise picked up by the
signal cable (read: “antenna”).
Even with a shorted RCA plug inserted, they will almost always produce a very slight hum when out of standby.
As mentioned by Ravsted above, if you cannot hear it unless very close to the speaker, it can be considered normal.Martin
Dillen
ModeratorThe band lamps intensity depends on the signal strength.
You could have a bad antenna signal.Martin
