I’ve never come across a VB with failed audio, but the first thing I’d do is insert and remove the cartridge a few times. The contacts are supposed to be self cleaning, and since the audio is routed through the cartridge, if there’s a dirty pin, it could cause audio problems.

I assume that you know the cartridge is good?

I’d also look down into the connector on the system to make sure none of the pins look damaged.

Other than that, I think you’re gonna need to tear into the system to figure it out. My best guess would be that either the amplifier has failed, or one of the caps on the amplifier board failed (common on other hardware, though I’ve never personally seen bad caps on a VB). Unfortunately, IIRC, the amplifier used isn’t a standard part (though you might be able to make a standard part work, if you’re handy).

Thanks DogP … today i opened my VB and check all caps and resistors.. all are good !
Later i check under the volume control.. and it had a lot of dust.. i cleaned it whit a spray of contact cleaner and ready.. loud and clear sound in the two speakers !!

Also i never opened before any VB.. wow is a awesome piece of engineering !

Again thanks for your advice 🙂

Great to hear! I was gonna suggest checking the volume pot, but I was thinking that it was just a single pot, not a dual pot… but now that you say that, I guess I do remember there being 5 pins.
