Hammarlund actually updated the circuitry and tube line up for the
Super Pros from the SP-10 (1936) to the SP-100 (1937) to the SP-200
(1939), going from the earlier all glass tubes to the newer metal
octals. As much as I like my 88s, I'd still take the Super Pro hands
down for multiple reasons. The only thing I ever found a bit odd were
the friction drives used for tuning, yet to this day all of them still
work flawlessly. Interesting too, is seeing that RCA adopted the
band-in-use window scheme used in the Super Pros in their last 88
models. RCA may have the edge in weight, though the SP-200 and
separate supply are right up there too.

For those who haven't run across it before, the Western Historic Radio
Museum pages are excellent reading on this topic. Henry does a great
job providing information and time lines on the different gear,
including a section of WWII and postwar gear along with prewar
designs. RAK, RAL. RBA-C, etc. There's also sections on pre-war
designs, including a page on Hammarlunds from the Comet Pro through
the SP-600.

Scroll down to see the different sections and info available. There's
a lot of good info there, hours of reading. The site certainly makes
it clear how fortunate we are to live in such a time where we get to
play with yesterday's best technology.
