I finished my Jersker recently but haven't had time to add it to my
website. Yours sounds healthy enough. I did not see a freeze with
mine, going very slowly, but can't say yet that it won't. What happens
to the output when it freezes? Does it just stop? Does it migrate
toward a high or low voltage? Have you tried different LM13700 chips?
It's quite an interesting sine wave generator. I wish it had a fine
tune pot on the rate, which is very wide range and sensitive. I'll be
experimenting with it and making some recordings that I will add when I
put it up on my website.

heya richard!
the intro to that jerkass mp3 has it in 'freeze mode'. the last centimeter
on my rate pot goes into that constant voltage - but i have not done any
measurements yet - it could be just going very slow. i used a recycled
pot from an old mixer and i used mylar capacitors. so maybe a trimpot or
just swap out a better parts might fix it all. but yeah first i will
try swapping the lm13700s with others - i'll let you know!
the rate pot really is sensitive. i was debating putting a 10 turn pot?
just use the mod cv in for coarse changing? there is enough room on
the bridechamber for another pot - the double well chaos could use
some fine tune pots as well - tune in tokyo!
