Just restored both these beautiful Lasonics. The 931 is near mint and still has handle plastic. I did however have to replace gear for function because someone used the generic replacement kit which I didn’t like so I got the new metal gear from Ingolf plus an extra cuz you never know. Both units were cleaned and new belts and pinch rollers. Got a new motor for 931 and finally got deck fully working. Luckily I had labels already to add to the finishing touches. Not units look and sound amazing. The 920 was packed like crap of course and had damage to bottom 3 backside posts which I used jb weld and it’s very sturdy. Also has damage to the ac/dc switch so replaced it. All in all I’m very happy 😃. Thank you again Ingolf!!!
