I've got my hands on a GR1225 repeater with an RFE4000a (Celwave
633-2a-2n) notch duplexer and a phone patch.
The repeater had some questionable solder problems on the output of
the final due very likely to the poorly

Dave,
I've tuned a number of these 633s and had no problems. They are pretty
much notch only with wide pass. Often get over 90 db notch with
little, less than 1 db, insertion loss.
I would think you have some internal problem, maybe from
