Hi.

These mixers are special. I have 8 of these and 1 scrap  sam82 for spare parts.

What mod is the best direct out mod out there? And is there any one that changed the IC for the discrete options around?

Would you be willing to sell the psu transformer or if not, the whole psu board for the one you have for scraps? Desperately looking for an original transformer for this (which is impossible to find since it was a custom job). I'm located in Sweden!

Hi everyone!

Does anyone recognize this fader? Make/brand? It's a direct replacement for the lower-ish quality 10K Waters faders (LM 4A-220, can't find any info online) originally used in the SAM82's. The photo is from one of my units.

thing is, I'm fixing up my two SAM82's and really want to replace all of the originals.

Hey!

I have a spare PSU unit, but I would recommend sourcing a replacement power transformer. The original Lundahl transformer vibrate quite a lot... I guess because of age. Excessive current draw (from leaky caps etc) is/was not the problem with my units, or any of the others I've repaired.

I'll look into the fader foot print. There ought to be a match out there. A standard ALPS fader would be way better than the original Waters' (that might or might not have been OK when new, they're horrible now).

Still interested in finding out the make/brand pictured in my post.

It's a cute little mixer,
never heard about it before.

Seems like the Swedish version of the Alice 828 (UK), layout arrangement is the same, also directed to the same market.

It's a great mixer, really! Sounds very, very nice.

The SAM82 was designed by SATT (Svenska Aktiebolaget Trådlöst Telegrafi - a division of AEG/Telefunken) for the Swedish Radio and Television. Used by many a engineers, among them Gert Palmcrantz who made some brilliant jazz- and classical recordings on the SAM82. Sold commercially too, but I don't think that many units made it elsewhere.

I can't help but think the Alice 828 looks a lot cheaper? The layout resembles those old Studiomaster desks, but with the added luxury of transformers? The BBC must have modified it/upgraded it? Am I fooled by the looks?

SAM82 was a pricy product. The only downside I can think of is the faders, but they were probably fine when new. Waters MFG (Maryland?) is/was unknown to me, not sure why the SATT designers chose them in favor of Bourns or any other renowned manufacturer.

Yes probably the Alice 828, was more affordable but I don't really know the price when new,  it seems to be earlier also. The 828 was UK made and had Belclere or Sowter transformers at the input, and the first version had a simple discreet mic pre circuit. EQ in every channel.
And a Limiter in the master.

Was used a lot in used Radio stations. Like the SAM 82 it also had provision for battery operation for location works.

Looks nice the SAM82, pretty tidy circuit and layout

Hi all, hope you are well in these crazy times!
I've been thinking about a easy direct out mod. What if I put a switch pre fader (basicly at the optional insert point) that sends the signal to the fader or to a standard line balancing transformer. In this senario the preamp only have to drive one input stage and not two in paralell.
Is there any potential problems with this solution?

as far as I can see you could use the "insert send" output as a direct out,
I would do it that way
