Not to hijack the thread but on that note, does anyone know that the
unkeyed voltage on a Drake l-4b should be about on a 240vac line?  I
have been suspecting it has been dropping but don't remember what it
was originally.

Of course it couldn't hurt to rebuild the ps, but I don't want to do
it if it is still doing the job.
