I am in the midst of restoring a Hallicrafters S-40A.
I think someone has changed the stop on the bandspread
capacitor. AFAIK all H receivers have the bandspread set
at 0 and this represents minimum capacitance. On this RX
0 has the bandspread cap completely closed and the
frequency calibration can not be brought in. If set at
minimum it sets up fine. There are other signs that the
bandspread cap has been fooled with.
I have seen one picture on the web which looks like
the dial pullies have been strung to correct a similar
problem. This is not what is shown in any of the S-40
series service material. My question is: will someone
confirm that the S-40 series bandspread cap should be at
minimum with the dial at 0 and has anyone else
encountered this problem?
The peg which forms the stop seems to be firm in its
socket. If its sticking out on the wrong side I may have
to restring the dial pullies to compensate. Thanks for
any help.

Short answer is yes, there's a mistake in some of the
original literature that had the dial going the wrong way.
Its been a while so I can't recall the specifics but it
sounds as if you know the way to go with it.

Now I am confused, what is the "right" way? Should the
dial string cross over at any point? on the stuff I have
from the web its not shown that way.
