Re: 519 -- broken rate generator; stuck at a very high frequency?

Couldn't find anything amiss...all the passives appear to be fine. I scoped the multivibrator as shown in the schematic, and it is works fine. It responds to the controls as it should. I reckon the problem is most likely the avalanche transistor. Luckily, I also have a 577D1 now...
