What is so special about a GE superbase anyway?

Ah, is the 8719 chip getting the full 8 Volts DC? If not, this kind of twitch can result.

I'll check that this morning. The cap thatvthe clarifier was connected to had 8.06v on it. I'll see whats going on there and report my findings.

On the 142 gtl, the mb8719 pins 15 and 16 are both high. I see this condition on channel 39. Ch 39 gives the correct combination for 38 I've tried everything to get L13 to tune into the correct channel pattern but its always 10k down. No disturbances were done in and around the 8719 and I get 8 solid volts on the 8719. Nothing different than when the mod was in place, they moved the crystal from its spot along with the tuning cap, added any upper and lower crystal to the noise blanker/limiter switch and cut some traces to free up the switch for the mod. I pulled all that out and placed the correct crystal and tuning cap back in their respective spots. The clarifier is very odd. Seems like once it gets below the 9 o'clock position everything cuts out. No tx no rx. I took it off the mod and replaced everything as per the sams diagram for the clarifier. Also put back r187 and d36. USB doesnt tune at all to the "5" on TX. Example, 27.385 is 27.388, What the heck am I missing?
