And now the fish in the North Sea near Katwijk are swimming keel up, poisoned by nicotine polluted water ...
And the whole West Coast of the USA and Canada is poisoned by Fukushima.
Warnings in Canada not to eat fish from the Pacific.
That's just the start. Soon, the rainfall in Western Canada and the USA will be polluted with Fukushima radiation.

I finally got around to restoring the pair of Beovox MS150.2 speakers I picked up a year ago. Thanks to a crossover network recap kit from Martin and a woodwork restoration lesson from Søren Mexico, the project was a success. I still need to fix the grill cover posts but I have the speakers hooked up to my Beomaster 8000 and they sound great. Here is a picture of them in service. The MS150.2 speakers are the ones without grill covers. The other two are MS150 speakers (they also sound great). In case anyone is wondering...yes, the Beomaster 8000 can drive both at the same time...and, yes, they are loud.
Stupid double-post again.

Life is unfair: you have one pair too much and I have none.
I could never find these in France at a reasonable price.
Oh well.
sonavor:
Just love it. I need(?) one more pair of those speakers. For now I have to be satisfied with MS 15 + Penta.

Availability and prices of vintage audio is strange. I started out just wanting a pair of MS150 speakers to see what they were like. They don't come up for sale in the USA very often so I don't know if they sold very well here. When I found my first pair, they were very inexpensive and sitting in someone's shed. Those are the pair in the picture with the grill covers on them. Then second set I also found very cheap. They were several states away but close to a relative that I had pick them up for me. I bought them because they were the MS150.2 version and they were also very inexpensive. The third set are a second generation MS150 (don't have the rosewood veneer on the back of the cabinets). I acquired them because they came as part of the whole 8000 system I bought from a local seller. That system was also very inexpensive as nothing worked and I had to rebuild it.
Great looking system, John, and I wish I could hear it some day. I'm curious, though. How often do you use the turntable? Only one of my tables is set up any where near that low, and I rarely use it.

Since I have set up this 8000 system I have started to appreciate the whole B&O system concept. Back in the 70's I bought my B&O turntables to be the turntables in my "separates" systems. With the whole 8000 system everything works together beautifully. I press play on the turntable and the Beomaster comes to life. I press phono on the Beomaster and the turntable begins to play. Even though the turntable does sit low, I find myself using it all the time. I am using a Beogram 8002 right now. It is great but I plan to rebuild the Beogram 8000 one of these days. I would love to find a B&O cabinet for the Beomaster 6000 too but the B&O cabinets are hard to come by in the USA. I was extremely lucky to get the SC80 that I have.
Restoration of S75 speakers. Woodwork guide from Søren Mexico, Thanks!
Looking good Aymeric! \
Another 2 units from a white Beosystem 6500. Top plates where badly damaged so I had to look for an alternative and put stainless steel mirror polished panels to replace including the sides. Cleaning, polishing guides from myself and bling bling.

Good work Aymeric, beautiful wood grain
Collecting Vintage B&O is not a hobby, its a lifestyle.
My VX7000 saved from the dump and working! What a beautifull design.
And I found a sensor in my closet new in the box meant for the VX5000 and working on the VX7000 as well.
Nice leslie :) But love black more.
I received a pair of M100's today Better than christmas.The wood was ugly, but fixed that before it was light today.With a pair of S75 on top.
The wood looks nice now:) and they are huge..
aymeric:Nice leslie :) But love black more.
But I don't!

Where did you get your ESR measuring device?
Check Ebay.com (esr tester) and you will find loads of them for around 20-30$ (made in China)
Found it, actually 20 dollars, including P&P. Thanks Leslie.
Think I'm gonna buy one as well, what's your choice Jacques?
And this Eeprom programmer what I bought for copying SW upgrade for my BM4500's
And Eeproms
I'll try the same as above!

And find a nice housing to put it in...

Very nice to see Leslie
Don't know that you also loves Beocords Videorecorders.. When I was working by B&O we dumped very much VX7000's to the garbage place ;)
Typical Beoworld fail, can someone delete the two posts above and also these post ? ;)
Thank you ;)
Before you all go running to buy a Chinese cheapo, with no guarantee of frequency stability and accuracy to give you the correct numbers, take a look at this one - The EVB ESR Meter in your own backyard - Portugal.
The designer speaks our language, and offers excellent after-sales service, in case you blow the device with a charged capacitor.
It comes with a case, connects with normal probes for instant no-wait in-circuit checking, and is available in a kit, which I built with no problems.
I've owned mine for over 10 years, and I wouldn't dream of using a Chinese unit, in order to save a couple of pennies.

Thanks Menahem, think I'm gonna go for that one!
And ordered!

I have one of those as well and can only recommend it. The beauty of it is that most of the time you can do the measurement in place, without desoldering the cap and that saves a lot of time (unless you are planning to replace all caps anyway, in which case you don't need an ESR meter in the first place). Beginning hobbyists should save themselves some grief and get the ready built version, there are a lot of components to install wrong and the price difference is next to nothing.
As always, having a fancy instrument alone won't get you far; you need to know how to use it and how to interpret the results.

Sh1t, this meter does not show uF on the display, so now I'm in trouble how to "interpret" the results!
Think I'm going to buy the "Chinese" meter as well also to compare the result with the one I bought now.
Salvador: Very nice to see Leslie Don't know that you also loves Beocords Videorecorders.. When I was working by B&O we dumped very much VX7000's to the garbage place ;)
I don't love them but this one was nominated for the trash bin and I could not resist to give it a cosmetic refurb. And I still have old VCR tapes that can be used now!

That stailess is great! I used it too to replace alupanels.
blah-blah and photographs as needed
"Sh1t, this meter does not show uF on the display, so now I'm in trouble how to "interpret" the results!"
The EVB ESR meter shows the result in OHMS only. It does not show capacitance. For Capacitance, I have it on my Fluke multi-meter.
Generally, on these cheap Chinese meters, the capacitance shown is so far off, as to make the reading totally worthless.
For troubleshooting, you don't need to see the capacitance. You check the ESR in-circuit, and once you find a cap with high-ESR, you remove it. It's bad already, so what benefit is gained by seeing its capacitance?
Anyway, you can't check capacitance in-circuit, you first have to desolder one leg of the cap. And are you really going to do that unnecessary work if the ESR checks OK?
I so rarely bother to check capacitance in the real world of every day repairs - it's generally unnecessary.
The ESR in OHMS is your PRIMARY trouble indicator.
