I never owned a tuner of any type until I stopped using rigs with tube finals
and pi network output, and almost never need one with an amp using a pi-net
output. Of course a pi-net is a limited range tuner. I started looking for a
Drake MN2700 after a friend told me of using one for several years on a BC610
running full output AM on 160 meters feeding a full wave loop. He says it even
runs cool.
