My question is specifically how do I connect the next stage to the
output of the triangle wave generator? no matter what I try the signal
disappears across whatever component is there. Its driving me freaking
crazy, I just want to compare it to a DC level and make a nice PWM but
the coupling is killing me. The tri wave gen is fig 44 in section 7.4
of the AN-72 app note, a quick goog search will get it for you. Please
someone tell me what to do before I go crazy
Thanks

Firstly, this is about National Semiconductor AN-72, I trust.
Secondly, these Norton amplifiers are usually run with a single
(+) power supply, so the triangle wave will always be
DC-biased. I hope your 'next stage' isn't a high gain
difference-from-GND amplifier, or it'll saturate.
Have you tried a blocking capacitor?
