Hallicrafters SX-110 question
 

Howdy all,

Along with the below post/radio. I also received an SX-110. I got it to
receive a station, but after the long trip back home from AL, I can't get
the radio to receive anything. I re-seated all the tubes and did not see
anything caps/resistors that were burnt. All the tube that are clear have a
glow to them. The speaker does not have any static, well, occasionally there
is a little, but not much.

What to do? Where should I look first?

Also, there looks to be some type of mod? There is a wire that comes out a
hole under the speaker connection. It is like a common 2 wire houshold
extension cord that connects to a wire that runs from the avc on switch to
the receive/standby switch and the other wire goes to a cluster of resistors
that is back and center of the radio.

Any one?

Thanks again for your earlier replies to my other questions!

Thanks in advance!

Jim

Maybe take a look at "Troubleshooting a Superhet Receiver" URL:

Good Luck

About the worst thing you can do to an older RX that has not been plugged
in for years, is to plug it in and turn it on without recapping the RX. It
is possible that one of the caps shorted when you first plugged it in and
taken out something important like a transformer or IF can.

You rarely can fix a boatanchor without at least a schematic to tell you
where you're going. Suggest you download a manual from BAMA
http://bama.edebris.com/manuals/hallicra/sx110/

Then figure out that haywire modification, and go from there.

Was it receiving anything before the trip?

Hard to know for sure based on your description, but it's *possible* that
this 2-wire pair went to an antenna transmit/receive relay. Those relays
usually had an extra SPDT switch for muting the receiver during transmit. I
used a similar arrangement on a couple of receivers.

If you're feeling lucky, you might try shorting the two wires together.

Can you use a multimeter and a soldering iron? If so, you can almost
certainly troubleshoot and fix your radio.
