[Hammarlund] sp-600

Hi Dan,

        The SP-600 is like all other old tube radio's.  There are probably
quite a few old dried out electrically leaky paper capacitors that effect
the performance of the radio.  If you look under the radio and find a bunch
of black tubular capacitors with color bands on them that look like very
large resistors that's probably the cause of at least part of your problems.
Some of the later radio's were lucky and had only ceramic disk caps
installed in place of the black plastic tubulars.  But beware sometime
having ceramic disk caps under the bottom side doesn't mean there are not
paper caps in the RF Deck.  I have one that is like that awaiting some bench
time.

If you touch something and the sensitivity increases something probably
loose.  Be careful in there...there are electrical contacts that can be
damaged that are hard if not impossible to find.

As AL has pointed out you need to get a manual and get familiar with the
radio.  Owning an old tube radio requires one to be knowledgeable about how
they work and equipped to handle repairs because there aren't any shops to
take them to when something goes wrong.

There not for everyone but they are great radios...

By the way...the SP-600 was the standard for MW DXing for many years...Still
can hold it's own with the new radio's...just a little harder to use.

Cecil...
