Ditto.vovkus - good to hear I made the short list. Waiting patiently... pretty exciting that someone with your capability is able to do this and bring some of these units back to life.
On this point only three words. It is alive!
All original functionality is recovered plus I did some modifications.
Firs 5 PCBs are ok, but they will need some very simple modifications. Simple comparator is not working for head sensor, I converted it to variable gain amplifier.
During debugging I accidentally destroyed ADC LMA-1 stylus. Not related to the controller.
Interesting fix but your cartridge alignment is most probably grossly off since the cartridge is setting so far back in the headshell.Sorry to hear of the damage to the LMA-1. They are a little pricey to replace. The LMA-1 I had was damaged when I got my Accutrac 4000. I removed the Accutrac cartridge from the plastic cartridge mount and replaced it with a Shure cart and stylus . The cart I used set back far enough to allow the head shell sensor to still work. I epoxied it in place.

It looks that way but actually it's not. The front of the headshell needs to be exposed so the sensor can shine down on the record. I used the Heybrook universal alignment protractor to align the cartridge in the head shell and it aligned perfectly. The set back is not a problem.Interesting fix but your cartridge alignment is most probably grossly off since the cartridge is setting so far back in the headshell.

Vovkus said this in a previous post.All I can say is WOW! Outstanding work here vovkus. I dig the add on for IR vs the original remote but I am a traditionalist. Will the old setup still work as well? Thanks for all your hard work here as well as for taking the time to share it with your AK community. Can't wait for the final, ready for me version.
DittoNice idea. I like that.
