As I recall, Rus Healy et al's July-1992 review stated that the TL-922
design is somewhat dated. Surely this is the case. However, I believe
the 922 is potentially a trouble-free, competent amplifier -- provided a
few circuit improvements are made. There is an article on my Web site
about these improvements.

The input swr is c. 2.5:1 on 12m and 17m unless the tuned inputs for 10m
and 15m are mistuned. However, by using an antenna tuner, one can make
do.
