Hence the moniker "Mighty Fine Junk." :)

In reality, there are several very good products offered by Mr. Jue.  You
just have to know how to pick them out of the junk pile.  One hint is to
discover the designer.

All of this proves my point about Ameritron amps.  They make the Heathkit
amps of yesteryear seems Collinsesque.  When are you newcomer hams going to
learn that anything that comes from MFJ is junk.  I'm sure the ARRRRGHL
loves them because they spend a lot on advertising in their s--t magazine.
