What are you working on now?

The benefit I now have is that my high frequency hearing doesn’t really go much over 10KHz so even pretty poor speakers sound not bad! The advantages of age!

Introducing.

Since I finally got around to solve the issue with my Beomaster 7000 not turning on the amplifier section (TR19 was defective), I thought I would continue a little TLC for my Beogram CD7000. I carried out the mechanical adjustments in the service manual as I thought the drive was slightly noisy with some CDs making a whirring sound. That seems to be gone now. Next up was reconfiguring the transformer from 220V to 240V. The hardest part was to get the damn plastic protection cover off. It takes quite a bit of persuasion while pulling outwards at the front and trying to slide it back at the same time. After that I unscrewed the transformer and looked at it. After a short while, I figured out that the jumper needed to be desoldered, moved and then soldered back in the new position. Quite easy. I believe the benefits are that the unit should not heat up as much as before and perhaps also stress components less. That completed the restoration of the Beogram CD7000 that I had previously recapped and changed C2103 in.

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

I have a BeoCord 6000 (VHS) that did exactly that while my wife was watching a video – there was a loud shriek as smoke poured into the living room!  The smell just never went away so rather than replace the capacitor I simply took it to the recycling centre and replaced with a V8000 from my ‘store’.  It’s not like me to dispose of something repairable, and I regret it to this day.

Whilst on the topic of the thread, I did find time to ‘refurb’ a couple of Beo4s yesterday, an AV and a SAT DVD version.  I also did a quick audit of my B&O remote spares as you can see in the photo:

As I have said before, repairing Beo4s is not cost-effective:  If you want to end up with a perfect screen, a keyboard that hasn’t had some of the rubber picked off (who would do that???!!!) and a battery cover with all the retaining lugs present then it’s a fool’s errand.  In the past I have tried to fully restore every Beo4 that I come across but I can no longer get new DTV/DVD (non-navi) keyboards, so I may well start dismantling some for spares and swapping parts around more than I have in the past.

After fixing Beo4s I always leave them powered up overnight, and sure enough one of the two repaired ones had a fault that doesn’t appear immediately – the keyboard defaulted to DVD and then locked up after several hours.  It’s probably a faulty contact foil, so I will replace that when I next have time.

Have a great weekend all! 😀

Yes very persistent smell. Judging by other threads about B&O VHS repair you could have ended up in an endless loop on repairs over time anyway had you chosen to keep it.

To bad if these keyboards can not be sourced anymore. But swapping parts might also be a good strategy to make use of what is in stock.

By the way when will you have enough BEO4’s? 😉

I revisited the faulty Beo4 today.  I tried to get away with just cleaning the contact points where the foil is clipped to the PCB, but I couldn’t get it to work reliably so I ended up fitting a contact foil that had been removed from another remote.

Whilst testing I used the following useful picture/diagram to test the remote and prove that it was the contact foil at fault.  I got the diagram from one of Peter Pan’s excellent threads on the hifi4all forum here:  https://www.hifi4all.dk/forum/forum_posts.asp?TID=78664&PN=1&TPN=9

(there are a few of my Beoworld photos in Peter’s thread so I guess that’s a fair swap of copyright, but the diagram may have originated elsewhere because Peter usually annotated his work in Danish)

As before, I’ll be leaving the Beo4 powered up overnight to see if it still works in the morning!

I just noticed that the new screen (on the right) is a different colour, but clearer (especially when viewed from the side). All three have the contrast set to 04.

As always, I am starting random DIY projects and this one *should* actually make it to the finish line in a few weeks. I have modeled up a clone of the A5/A6 CD rack! I am currently getting quotes made for the glass in both sizes like the originals. The end pieces will be 3D printed.

I am a huge CD listener and have a few hundred CDs that will be put on display in my new music room here at home. I plan on building at least four or five of these eventually. I like the idea of having a few groups of CDs to organize by genre instead of organizing alphabetically like I usually do.

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

My bad with not knowing the function of them. Don’t worry I have used X2 classes of same type and brand as the ones that were in it already

Recapping the crossover in my Beovox RL 45.2. I wonder if I am able to hear a difference

I received some quotes for glass shelving and boy was it pricey. Seems like B&O negotiated a good price with its suppliers back in the day… the tinting and beveled corners seemed to drive up the cost a lot. Largely though there was a ton of polishing involved to get the edges smooth.

At any rate, I decided to just move on with some scrap ply from the woodshop. this is ~12.5mm ply with some white PLA printed ends. I made 4 shelf plinths last night, two in each length. Going to make a few different colors to see what works best with the birch ply visually.

Looks nice so far.

Have you considered making the glass/plywood piece out of granite? A countertop shop might be able to do this at a reasonable price using off-cuts. Just a thought…
