Hello,
i love these 555's been using them for 15 years, and your resident expert bill does some nice work - his circuits displayed throughout the website all run cool and clean - elegant and thorough work. thankyou kindly.
im not familiar with comparators though, - not that you need too be, - or so i thought.

im getting a lovely identical triangle wave from pins 2 and 6 - and a 50\50 square wave from pin3
but connecting it too pin 2 of the comparator with all the designated components - except a resistor and led as a load.
no matter how i twiddle the pot on the 393 i cant get the signal on the output - measuring it on a cro - been playing for 2 hours tried these comparators seperatley too make sure operational - ebay cheepies- but that seem too work fine otherwise -
not getting any love from the 393 despite bills clean inputs
cheers AAC's
