I hot glued two small 12vdc computer fans to the back of my AC4R which is in a
MS-4. One pushs air, the other sucks air out. Results is a cold AC-4.

Generally, transformers can and do run hot enough that you can't leave
your hand on them for very long. They will be fine like
this..but...heat does deteriorate plastics and varnishes like that used
inside. Electrolytic caps also have reduced lifetimes depending on
heat. So I have elected to
After rebuilding my AC-4 I decided to *NOT* mount it in the MS-4. The
cable from the AC-4 to the T-4X is so long (5 feet, maybe?) that it's easy to
find a place to put the power supply where it's out of the way but not
boxed in.

A while back I recall a discussion about the heat in the AC4/AC4R. Now
that my rig is back in the shelf along with the PS in the MS-4, I
notice that the back of the AC4R is too hot to touch for more than a
couple seconds. I worry about cooking the xfmr too much.

Yes Garey:
Any of the rigs with lots of connectors, card edges, and switch wafers
are an issue.
I never had done any cleaning on these switches at all since they looked
brand new. Even now, not a hint of the normal dark color on the
switches. But I could see the shiny rub mark on them so j
Fred -
It depends upon 'how much' reduction you need. If having the LOAD
control at minimum (0) and turning the GAIN down to no less than 9
o'clock is still too much power, then you may need additional
reduction. The BEST way is to reduce the Screen voltage on the PA, but
this is not simple
Welll...no it was not unlocked. I know what that looks like. and it
was /is 33MHz and 17MHz when fixed Rx is depressed.
This was stable, normally operating in all other senses but wrong frequency.
It must have been getting bad selection information out of the band

This just means that the 'low band' VCO is unlocked. The 'low band' VCO
covers 14 MHz and down. You should read about 17 MHz rather than 12,
which is probably why it's losing lock. If you switch to any of the
'high' bands (21 and up) and depress the FIXED - RCV button you should
see
Thanks to several immediate responses:
TR& is working again as it should.
After checking to be certain that the rig was actually running at 12MHz
(it was), I just did a very light application of Deoxit to the band
select switches. These were very clean...no hint of the common black

Hope you all are keeping warm. 10F here and all antennas iced up.
Have a problem that just started over the weekend with the TR7 here.
All works fine except when I try to select 14MHz. the display goes to
12 MHz.
