I have a Drake R-4C with the NB-4 rare noise blanker board installed and
working. Radio is in excellent condition. There are no filters or extra
xtals. Radio has been aligned and works to specs or better. I have the
Quality Control Tag, S/N 28003 made on Nov 18, 1977. There are no
modifications done to this rig, its stock like the day it was made. I also
have a Drake TR-4 with the speaker and power supply. 170 watts out on 80m
and 120 watts out on 10m. Fully aligned and ready to go. Some rust on
chassis. Electrically it works perfect. All is from a non-smoking
environment. I'm looking for a newer solid state rig preferably with the
auto tuner. What have you got?
