Your first check should be the health of your electrolytics, especially if the rig hasn't been on in years. If they are bad (shorted), you could lose your pwr xfmr, a very expensive repair. There's a gadget called an equivalent resistance meter that checks this, there are instructions around the internet for reforming old caps. Then, if they're OK, measure the output of the B+, and take it from there. But PLEASE, do not turn the unit on until all
this checks out. Best of luck.<br><br>Fred - KG6NYK<br><br><blockquote style="PADDING-LEFT:5px;MARGIN-LEFT:0px;BORDER-LEFT:#0000ff 2px solid;">-----Original Message-----

Doug.....<br>

I would suggest finding one symptom at a time, and posting it to the
group. This way, you can hope to get 3 or more responses.....if they
all agree, you probably have the answer. <br>
If they are three different suggestions, you can try them all....and
better learn what the line of thought is. <br>
In addition, this gives others the chance to learn as well by
reading along. Some may be shy to throw their $.02 in, but are
curious as to the progress of the repair. <br>
<br>
This is a very powerful way of proceeding....you get some very smart
troubleshooters all spinning their wheels to come to a successful
conclusion. <br>
<br>
I suggest starting with......<br>
1. Does anything light up? (tubes, light bulbs etc.) Perhaps a
fuse is blown. If stuff lights up, then at least you have power, and
a working filament transformer. <br>
<br>
Use direct simple subject (SHAWNEE REPAIR) to make it easier for
those to track the goings-ons.<br>
<br>
I've done this several times, and the bright folks on this group
have helped me get a rig (and tube-type stereo amp) running again!<br>

<div>I am looking for an individual who is technically savy
and is familiar with the Heathkit HW-10 Shawnee to assist me
in getting one of these working. I am not a technician and
have intermediate knowledge of electronics. I do have basic
test gear and I do have the HW-10 manual. I would like to
do this on line as a sort of tutor/student relationship.
The radio I have appears to be “all there” but hasn’t been
turned on in years. I tried it the other day and got no
response from the rig. I have access to a bunch of spare
parts. </div>
<div> </div>
<div>If you would like to help me in this endeavour, please
respond off list. </div>
