[Boatanchors] Halli SX-111

[Richard W. Solomon]

I do not subscribe to the "shotgun" approach when it comes to
replacing old caps. But, if there obvious flaws, then they need correcting.

I had a circa 1943 SX-28 that worked fairly well (all functions did what they
are supposed to do), it was a tad deaf on the higher freq's. All I did was to
re-form the filter caps (may not have even needed that).

I passed it on for what it cost me (zero, it was a gift). The SX-111 is another gift
that will find a new home shortly. I cleaned it up, gave the switches and pots
a shot of De-Oxit and it seems to work fine. I'll check the sensitivity later.

My comment on the "next generation" BBOD's came from the looks of them.
They are bigger in size and the color stripes are different than the "old" ones.
