The reason I asked is that I know there's a mod developed by two gents from this forum for the 62 that will let it get into the 25mhz region where I have a 1951 TV that could use a touch up. I have a B&K 415 that we bought new, but that doesn't do anything but 45mhz.

A few years ago there was a thread here on VK where someone found a way to successfully heterodyne down the output of a 415 to do 25MHz IF alignment....it was all external equipment that could be removed easily to switch between the two IF frequencies.
