I tried to fix those Timers S1-II. Unfortunately they were hardly used and I successfully restored just one of them – is 100% functional and in very good conditions. The other one has a display not working properly and missing a button.
On the picture “Timing gear from last century” you will also find Timer S3, printer P3 and also beeper. All of them still work.
S3 rear view – very good example of destroyed case from leaked batteries.
Delay time switcher is broken. My guess: the switch was probably damaged during somebody’s effort to take the timer apart.
Everybody, have a nice and busy winter.
