No vintage Bozak or Urei mixers on eBay for a while now...

Have we passed a rarity milestone or is this just a slow period?

I just recently sold a Bozak DLC on 12/23/10
http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MESOX:IT

item # 290515224266

and on 12/08/10
http://cgi.ebay.com/ws/eBayISAPI.dll...m=290510467531

item # 290510467531

These are ended auctions so they will show up on ebay for a limited time and you will have to have an ebay account to view them.

The mixers that I have listed on ebay have sold very quickly, so I think that this is not a slow period or a rarity milestone but a time to buy them before you can no longer get them in this condition any longer.

If you are interested in purchasing a Bozak mixer built by Buzzy Beck, please contact me.

I must have missed those recent BIN listings. There is a 1620LE right now sold by HTFR in UK but that isn't what I'm looking to discuss here. (@paul1979: I love the DJR400 but it's not vintage )

I remember not so long ago when there was always at least one live listing for a Bozak or a Urei mixer. Even right now there are less of the various Urei processing units that there used to be pages upon pages of, hence my wondering is this just a slower period for vintage electronics or are these type of units just getting harder to come by. I'm bringing this up because I've always wondered when we would get to a point where it would be virtually impossible to buy the 'real' mixers anymore.

I guess you are right John, those who don't have their vintage mixer yet probably better act sooner than later. I have had my Bozak mixer since 2003 but if I'm ever on the market for a second unit, I'll contact you for a quote.

$480... nice score!

You're asking what kind of caps to use as replacements? Other people will be able to give you more precise answers but for what it's worth, here's a pic of one of my Bozak's cards with the new caps. They were installed by Buzzy (via John Kimura) so I assume they are a good replacement part!



(apologies for the large image, I think it might be necessary though to read the writing on the caps)

Started fooling around with contrast settings in iPhoto to see if I could read the small print and I think I figured it out!

The blues are by Nichicon and the large red/orange says "Ind. Brasileira".

What is the correct value of the pots in your bozak? (Didn't ever had one here...)

Here in germany there's allready a shop where you can order old "black beauties". You can find it on

www.familygate.eu

The actual ALPS RK27 are the best alternative for the price. Think you'll get these everywhere in your country.

Lime Twig...The orange capacitor with the funny printing is a Mallory Brand Capacitor if you look real close at the print under it. I have a couple of these and they also came from Buzzy. The black beauties used appear to all be RK40 numbers and are dual 50K in both original Bozak & Urei mixers. The list from this company shows a possible match but it is a linear taper. All Bozak factory black Alps pots had eyelets for the wires and I do not think they are available very easily. The original Alps RK40 black Urei 1620 style pot that most people use for a replacement has pc board style mountings. If anyone needed the number I am sure I could get the original Bozak Alps number from Buzzy. He once told me that he has a lot of the original company paper work still on file.

i agree, my understanding is that the Bozak ALPs are rated for 10X the life of the Urei ones.... 1M vs 100K rotations, something along those lines....

I believe the Bozak Alps were a custom configuration....

GREAT SCORE on that early unit...


RE caps... folks seem to dig those nichicons with silk fibers also...
i've even had pretty good luck with inexpensive NTEs in a pinch...

have fun!

I would like to find a face plate but when was the last time you seen a Sliver one with cue on the left side?
it also has a scratchy master pot I was looking for info on how to clean them and came across this site.

http://www.head-fi.org/forum/thread/...0-disassembled

I'm going maybe do those same caps buzzy did on that card he's the expert.

I posted this ohter card from Mario to compare, looks like a difference in resistors. carbon composition vs. carbon flim please correct me if I'm wrong.

The green card shown by Lime Twig is and early production part. The brown card you show is of later production. For the face plate you may want to contact John K. of this board because he recently sold an original silver face mixer that had a mint faceplate from old inventory owned by Buzzy Beck. The que was in the later standard right side but I would think if anyone would have it that it might be Buzzy Beck.

Yes, I know, log taper is the coorect way. But a linear taper also works. tried it. Curve is different of course, but you can get used to it.


@Mario
You allready have RK40 50K log stereo?

Or do you use RK27?

[quote=bossa nolyx] Yes, I know, log taper is the coorect way. But a linear taper also works. tried it. Curve is different of course, but you can get used to it.

Back in 1977 Bozak corporation sent two employees to Japan to meet with Alps engineers to design and developed the RK40 potentiometers. Bozak had a 5 year exclusive lease on the finished product. These were custom tapers with military grade specifications for durability. Very few of these are found anymore. When the lease expired to Bozak the potentiometer was cloned by Urei for their 1620 mixer that originally used the Noble brand potentiometers. Some corners were cut and they were made a little cheaper but they were still superior to anything being manufactured at the time. No doubting you can make a linear taper pot work but this statement is a direct quote from Elliott Sound Products web site under the topic of Beginners guide to potentiometers. This is in reference to using a linear pot and adding resistors to make it become logarithmic. “All this tapering proved a rather expensive exercise, so manufacturers economised ("they" won't notice the difference!), and worked out a method of using two resistance elements of differing resistivity, and joining them to create what I referred to as the "Commercial log" taper. In short, it doesn't work (not properly, anyway), and the discontinuity where the two sections join is almost always audible”. and by the way to MainEssentials...the silver faceplate you need is available from Buzzy Beck. I checked for you and he is suppose to have 1 and only one silver originalface plate with the Cue switch on the left side. The CMA 10-2D is the model number on it. This was the first produced version of the DL series stereo mixers. Very few internal parts are interchangeable with the later model depending on the production date. The D mixer is a true stereo mixer in that it uses individual mono cards to create a stereo signal. These are tough to find in good condition. I hope this helps.
