Is there a difference between Linn LP12 lingo 1 vs lingo 2 other than the case?

If I'm not mistaken, later Lingo 2's had SMD devices. One of the big knocks on Lingo 1's was the filter on the line inout spewing out lots of crud. I have a very late Lingo 1 (power button is different from early ones), which I bought new, and surprise, no line filter on the input. I had my Lingo completely recapped in 2019 and it's working great. The recap was precipitated by an issue I started to experience at 45 rpm which per the trouble shooting guide (finally found it on line), it was indicative of a failing phase. Recap and now 100%. Botton line, in my experience, Lingo 1's are not all alike and Lingo 2's are not all alike. 

Have to agree with @dfarmer - the lingo 4 is a massive and impressive improvement over my prior lingo 1.

And as @daveyf said- the 4 is in a very slim box. Google it and you’ll see it looks unlike anything else Linn. Linn “split” the lingo by housing part of the circuitry on a board that fits within the turntable (think valhalla) and the rest of the circuitry in an external box. There are 2 other ways the lingo 4 is a significant departure from earlier lingos- the 4 uses a 12v motor while previously a 120v motor was used and the 4 does use a tach for servo control as does the Radikal (but in a way different from the typical direct drive scheme). Since it is a synchronous motor its speed is locked in both by line frequency which is tightly regulated and the tach. It’s a built in redundancy.

 

@lewm - the Lingo 4 has an AC motor; the Radikal has a DC motor
