Hi,
Since you have no manual, and are trying to figure why the SB-401 doesn't
work!
Try this, lift the top cover while facing the front of the transmitter. Look
inside to
the left front of the chassis. Are the crystals in all the sockets present
and the freqs.
marked on the chassis top? If not the xmtr was part of a transceive setup
with either
the SB-301 or the SB-303 receivers. It can probably be brought back to life
if these
crystals are put in. If you already have either the SB-301 or SB-303
receiver, and
you have the manual for those items, it will tell you what cables you need
to bring the
transmitter back to life! I have three of these rigs in various setups for
different modes
of operation, and I have only run into one the didn't at least put out some
power, and
that one had a single bad cap for the bias supply voltage. Replaced that and
it came
back to life good as new.

When you do get it running, go through the alignment completely per the
manual and you
will have an excellent rig for SSB/CW/RTTY operation. Quite stable and they
run
forever, seems like, as mine have been in operation for more than six years
with no
failures. Even the original 6146 tubes were in them! Good Luck.
