I'm an automotive audio and acoustic engineer. I design loudspeakers and full sound systems for new automobiles. I also dabble with studio, consumer and pro audio projects from time to time.
Well, both Pentas are reassembled.
One seems to work but produces barely any sound, the other makes a ‘pop’ when you plug it in and goes straight into protection mode. The displays don’t work on either of them.
Looks like they’ll be converted to ‘Beovox’ Pentas for the time being to see if they work like this, as I haven’t got time to look into the amps further at the moment, and I’m supposed to be using them at the Hi-Fi WigWam show the weekend after next!

I have been working on a non working CD and tape player in a Beocenter 9300 and have now finished it with both sources working again. It has been a dream for me for many years to get one of these Beocenter systems, and here it is all lighted up and ready to play all of it's sources :-)

The CD player go a new laser as described in this thread

The casette section needed 3 new belts.
This picture shows one of the old belts in the mechanism, and you can almost see that it has to much lenght and bends away from the straight line it should have.

It's not without reason that new belts make a difference. One of the smaller ones was also cracked and perished.

I just bought a pair of Penta mk1 speakers (see my freestanding post). And im planning on fixing the speaker surround foam rot and recap the amps. After doing a bit more forum research, it seems like some folks get their amp and crossover cap kits from a "Martin". Does anyone know how I can reach that person? Or is there a link or post somewhere I'm missing? Apologies if this isn't allowed.
Thanks this was where I was going to get them, unless there was another place tbe community went for this sort of thing. Cheers!
I just managed to modify my connection Hub to receive IR commands from my BeoRemote One IR ?
Hello Evan: Yes the charging base can be converted to run on 120. The primary of the transformer actually has two windings. For 24o, the windings are placed in series which is how yours is wired. To make it run on 120, you will need to unsolder the primary lugs from the transformer. T Lift them off and fold them over onto the other side of the PCB so that it bypasses the traces which connect the windings in series. Then you can connect the windings in parallel. You can also cut the traces on the PCB, but I prefer modifications that are non-destructive and can be reversed. Derek PS: I’m in SF as well!Hey Derek, Finally getting back to this topic. Here is the bottom of the PCB for the table charger. Can you show me which lugs to disconnect"? Login to view image Thanks, Evan
