I have the same problem.  In my case, the problem was traced to the
fuse.  It's a 1/8 amp fuse with a 22 ohm resister mounted inside the
glass (in series with the fuse element).  It appears as though a
significant portion of the signal is being dropped across this
resister.  A BSR unit contains an almost identical output curcuit but
without the resister.  As a test, I tried replacing the fuse with a
normal fast-blow of the same rating.  This solved the problem but
cannot be considered as a final solution.

I don't understand the function of the resister, but I'm sure Heathkit
had something in mind when they designed it in.  If anyone could
enlighten me as to its purpose in life,  a proper solution should be
almost trivial.

Please reply via e-mail.  I'll contact Heathkit before summarizing.  Thanks
in advance.
