Good timing as i am troubleshooting xmit on my NC40A too. I replaced Q7 but that did not fix my issue although there is some indication the new Q7 may be bad. What do you see as Vpp at C39 when you peaked it? I am only getting 2 Vpp which seems low. That signal is getting all the way to the base of Q7 but no output.
