The very definition of "pimp"

agreed, that is pretty swag. 
I have another doubt.
Is it original knob, or a replacement made in the lathe by previous owner?
I checked Google photos.....everyone has the same knobs.
The 3 big ones (tuner, volume, and Rec Level) are all solid metal. The rest are plastic.

In that case, how would you cut the splines?AE_Stereo said:I have another doubt

I reckon it must be cast unless someone is incredibly good with a micro modeller's rat tail file. I was surprised to see that the knob has the fitting for a split spindle in something of that obvious high quality instead of solid spindles with flats and a grub screw in the knob. Looks good though but.

I'd love to see that done at 1/4". Seriously, I would. Miniaturisation in electronics is one thing and has already come close down to its projected trough - for currently known materials - with junctions so fine that some are barely above a molecule in girth, but to do the same with a mechanical process would require something that could keep its form when the edges of the mill were deeper than their substrate. Sadly, graphine isn't suitable (yet?) and any metals that fine are only of use for wrapping a Sunday’s joint or a jacket potato for cooking.
Interesting images though, and a slightly smaller mill that serves a similar purpose is among the machines in my department at work, but that can cut nothing internal whose id is below around 11/16". If it could, then many of my old radios would have beautiful billet knobs by now.

Just for reference,every knob on my Telefunken Studio 1M is made from solid aluminum and each has a metric allen head to tighten it up to the shaft. Thats PIMP!

That's serious quality is what that is!

It really is incredible how some manufacturers created full on Home Stereo quality unit's that were portable.
Just wondering, what is the weight of that unit?
Two things that you touch first that tell you if the unit is super high end, the feel of a weighted tuner knob and the smooth resistance of the volume knob!

True they are metal, but I don't remember them being solid metal with no air gaps in them, like these.skippy1969 said:
Oh and the tape deck on the Telefunken is rubbish IMO ......Cheapest feeling keys ever!
In fact I remember one guy on stereo2go had all of his tape keys break off and fall down inside the unit, because of the cheap plastic chassis they're mounted on.

True but the deck works fine and it's easy to work on if need be. But yes I agree the deck buttons feel cheap.

23.5 lbs isn't bad...I mean, I have radio's, with batteries that weight that much.Reli said:
This would be a system that you have in the house and when family and friends come over you move it into the entertainment room and let it all hang out! Is that a good assessment?
Does it have one of those clip on battery packs?
No battery pack at all....just AC.
I think it's the precursor to the modern-day "executive system" for your office or den....
For a basement party you would want something louder. I haven't found a 3-piece system with 4-inch woofers that I would describe as "loud". They might put out decent bass, but they don't put out enough mids to be considered "loud". Same thing with the Telefunken. Sure, it can fill a room with warm bass, but nobody would describe it as "M70 loud", certainly not loud enough to compete with the noise of 20-30 people having a good time.

Interesting images though,
My post was half jokingly. If making such an Aluminium knob is difficult "today", I wonder how these designers made the complicated tape mechanisms in the 80's. They would not have a computer or 3D design software back then. They must have developed the mechanisms by trial and error and perfected. How did they make the first prototype? Tape mechanism is a pure mechanical device, even if it is controlled by electronics in the later years.
It is a nightmare to even open up a working deck.
Examples are the Aiwa 990, Pioneer SK-71/95 mechanisms. SK-71 has a hidden mechanical counter to repeat songs based on the counter start-stop positions.
