[Hallicrafters] FW: HT-37 Thanks and one more question

Mike, 	
	
Taking a quick look at your ISP, you can solve the problem by getting your own
account and stop using the one provided by the college. Many run antiquated
software, such as Pine. There is the source of your woes -

Sorry, folks - this message was originally sent to the reflector on
December 15 but the system's SPAM filter rejected it.  I'm trying to
fool the filter with the hope that I can post it.  It's become a grudge
match.

Dear Mr. Hollingsworth:

The explanation for your current-induced transformer buzz is actually
quite simple.

Unlike the modern stuff, each piece of vintage equipment has a soul of
its own. When one of my vintage rigs does something that defies logic, I
realize that the soul of that particular rig is f e m a l e.

As fate would have it, ALL of my vintage equipment is f e m a l e...

This explains the very nature of our relationship with this
equipment....the evidence is too compelling to ignore.

        Subject: [Hallicrafters] HT-37: Thanks and one more question
       
       

        Thanks to everyone who gave me the good advice on the HT-37. I
finished it
        and it has full output on all bands but Ten, where it has about
ten watts.
        Works great on all modes. I replaced caps, tubes, cleaned
bandswitch, and
        replaced rectifiers with solid state.
        One remaining question: transformer buzzes very noticeably, with
either
        solid state rectifiers or the tube rectifiers; BUT, when I bring
the line
        voltage up to 110 or so with a Variac BEFORE turning on the HT
37 power
        switch, there is no buzz.  Why would that be ? There is even a
buzz when I
        turn on the power switch and THEN bring up the voltage with the
Variac, but
        not when I set the voltage with the Variac and then turn the rig
on.  Any
        explanation ?
