[Hallicrafters] B&K 500

[TC Dailey]

Rich,

I too, have a B&K 500.  There are several tubes that are not listed in the
charts for this one.  Also, you'll discover that certain types, such as a
35Z5 take an 'adaptor', which mine didn't come with.  If you or anybody else
has info on the various adaptors, listed at the bottom of the tube-settings
charts, I'd love to get 'em.  I suspect I'd have to build them, but that's
no biggie.  I have constructed a couple for some rectifiers, but that's all.
