Found this Schlumberger 4017 Stabilock in a local junk yard. Have not turn it on yet, will open it up to make a inspection first, is it wort spending
time on this boat anchor?
-
I for one would try to get working...
-
Clean inside, staggering amount of trimmers, counted to 46-47 powers up, beeps, crackles and burps a bit, but after settling down some signals.
Edit: found schemo for 4010, 4020 4021 4022 quite straight forward machine, i save the 10Mhz ovenized crystal reference and junk the rest.

Keep those decade switches, they are quite useful at times, especially make sure to use a wire to keep the whole assembly with the end pieces and spacers together. They can be BCD, reverse BCD or even 1 of 10 selection depending on the model. Quite useful at times to do selection of data or for selecting data that can change occasionally.

yes, thanks for the reminder! :-+
-
The rotary switches and pots on the front may be worth keeping as well.

I'd try to get it working as well, you could build a complete radio service bench around an instrument like that and it seems a shame to scrap it.

Oh that's a real shame, it'd be a great piece of kit if you were into radio repair, servicing or homebrew.
I'd have been very interested in buying it as faulty if you were in the UK
