Good Evening All,

        I have been catching up on small project of late. One I what to
finish up on is a Heathkit HM-10-A Tunnel Dipper. I have had this one for
awhile, seems to work O.K. after some TLC. But setting the meter is a bit
of a pain. I found a modification in a back issue of 73 magazine. You
remove the meter set control and replace it with a smaller value, and
then add to fixed resistors to make up the difference. has anyone
performed this modification and if so how well did it work. I have all
the parts on hand. But in order to perform the work you fist must
disassemble the unit. But if I move a head with this I will also redo the
dial drum overlay. I think I may pull if off and scan it for future
reproduction if needed. Any suggestions or comments are welcomed.
