Yep, my juno has the crap oscillators. 80017a
Its been with a guy here in adelaide for 6 months and he just hasn’t got around to fixing it.
Anyone know who can do the “acetone fix”? Or, fit new chips?
Please…
Pretty please…
I miss the old girl.
It is not a hard repair and it is well documented on the internetz… Remove the bad voice chip soak in acetone to remove covering and reinstall and hopefully it works… Or… Take it to a consumer tv radio repair place with some links to show the repair or buy the replacement voice chip and have it installed… About a 1hr repair job…
I’ve had mixed results with the Acetone bath and about 1 filter chip dying per year. I decided to just replace the filter chips.

If you decide to do the bath route have the tech install sockets so you can replace the chips easily.
The faulty 80017A chips are actually VCF/VCA’s not oscillators. The wave generator chips (MC5534A) can go bad but not nearly as often. There’s diagnostic info on the previous post link to determine what’s at fault.
