ADC LMF1 tonearm question

I got this with a Kenwood KD-500 craigslist purchase recently. Seems like a good low mass arm. Haven't been able to listen to it as the interconnects are MIA.

I've cleaned it up a bit but can't get the cueing lever to work. The lever moves but the bar doesn't raise. It's stuck down. I've never done this kind of work. Anyone familiar with this arm or what taking this apart would look like?

Hope it will help.
 
Whoever actually built these for ADC also supplied the entry-level Linn arms. The entire lift/antiskate platform is identical on the various Linn Basik arms, and still looks almost unchanged today on the Akito. Hoping somebody in that wider community can help you out.

I guess I'm lucky with my Basik Plus, 25 years of trouble-free service and still going strong.
 
Could be the silicone goo that makes it work is gone. If it's like the Sumiko cueing pots you can remove it and disassemble. Need teeny Allen wrenches and screwdrivers to do that.

Some Linn tonearms was built by Jelco. The ADC was probably made my Micro Seiki.

UMM no. ADC built the arm, and they built the Linn arms up through the Akito. Jelco never made an arm for Linn. Acos Denki Co. = ADC. Not the same ADC company who made the cartridges.

Marc, I usually don't question your info, but did Acos Denki make them for Audio Dynamics Corp? They were certainly Japanese built, looking very much like the tonearm found on the Concept 2QD turntable. The manual and photos of the arm make it from Audio Dynamics Corporation, both the non-detachable LMF1 and the detachable headshell LMF2:

the one in the box was built by ADC(japan), for ADC(america). the other was built by Jelco for ADC(america).......the bias and cue devices gives them away.
Sumiko doesn't make arms, Audioquest doesn't make arms. Although their names will be on them. There were several versions of the 1 series, I guess due to manu date. One of the series, you can pull the arm tube assembly (complete with C/W) from a Linn LVV and swap it.
More to the point of my post I guess was to point out that Jelco never made arms for Linn.....ADC did up through the Akito (1) equipment was moved to Scotland and the Akito ( ll ) was built there. with the same tools, materials, etc.
 
Hmm, so based upon this info (and the antiskate adjustment) the ALT-1 was also built by Acos...
 
Not that any of this has much to do with the OT but I think there is some confusion with company names versus brand names here. The Japanese company was called Koshin Electric (English) or Koshin Denki (Japanese). Acos was their brand. I don't think there ever was a company called Acos Denki Corp.
 
So after some messing around, there is a little grub screw on the back of the cueing mechanism. Messed around with the lever and this screw for a while and got it working again. Just working on different positions I seem to have found it and it raises and lowers nice and smooth. Everything online says this is sealed and shouldn't need new silicone. All that info is from Linn boards, so thanks to all for pointing out that these are cousins.
