I received the following question from a visitor to my website. Anyone out
there have an answer? Some of you have stacks of old CQs, etc., much bigger
than mine. I usually frown on modifications to old gear, but this sounds
like it could be harmless fun.

I thought perhaps you might be familiar with an old article describing some
modifications (reversible, non-destructive) to the SX-28. It described a
series of improvements, one of which was an outboard additional i.f. stage
using a 6BA6. Another was a product detector using one and a half 12AU7s. I
think it appeared in an issue of CQ Magazine or similar publication,
probably from the Fifties or early Sixties.

By any chance do you know what magazine and issue/year it appeared in?
