#238 Hammarlund HQ 140 X Repair Part 1

In todays video I take the first steps and over view of restoring this Hammarlund HQ 140-X. We soon see there are many problems with the IF stage, crystal selectivity and AVC. Going to take a lot of troubleshooting and multiple videos with this one.

It is all about observation of the current faults before any work is done, then careful documentation before and after fault correction, very sound approach IMHO, regards Colin.

Nice old receiver that's worth repairing and in very good shape. Never owned one but one may come along someday. Thanks for the in depth video on how to trouble shoot and I am looking forward to part 2.

Apparently I lucked out on a RCA Chanalyst II that was owned by a non smoker. It just smells of vintage 1940. Four eye tubes and all working, ahhh!
Seems the HQ- 140-X needs your magic touch Buddy.

Super fun. Thanks for sharing the project. Your video is much appreciated.

Hi Buddy

Another fantastic video and am glad to see that 140X being brought back to its glory. I can’t wait for the second video on this one. Hope all is well with you and always nice to stop in to see you.

Nice job! UGH, smokers ! I can just see some guy hunched over his desk, yellow fingers holding the ever present cig, smoke drifting into his eyes as he tunes in late night DX. I knew someone like that, he stunk so bad you had to stand 5 feet or more away to talk to him. GREAT person but the smoke smell UGH. Mr Carlson did a video on this same radio a while ago, it is nice to see different problems and yet you work through them much the same way. The Analizer is the best way to do the alignment. I have yet to do one but I do understand why it needs to be done that way!

Waving at you from Australia, well done Sir.

A really nice radio.
I have a number of observations, recommendations, suggestions, etc. First, mostly for in the future because I suspect that you are done with this one now, I would like to suggest that you give "Odo-Ban" a try for cleaning off the tar from cigarettes. First of all, it is a very good cleaner. It is also a disinfectant, and does an excellent job of eliminating odors!
I noticed that this radio uses the infamous "death caps" across the line to ground (both hot and neutral sides to ground.) Really should be replaced with Safety Caps (Y type) if they are not already.
Wow! You just got to the point where you were turning the XTAL selector knob and man were the patterns lousy!!! Bet you will make them look beautiful when you adjust it. I guess this is going to be a multi part video. Looking forward to the other ones soon.

The varible capacitors in these hq 140s 129s etc are superb works of art and precision crafted . very fine varible capacitors. dont find that any more. clean up jobs can take lot of time dials chassis etc . labor of love, takes long time. I have restored 2 of the HQ 129s long ago had a HQ 140 as well superb AM receivers and cant beat AM broad cast band DX either way better than some new junk they make these days. thanks for video radio shop .

Savogran Trisodium Phosphate (also known as TSP) will work to remove tough stains and is an effective de-greaser against cigarette tar. Just a small amount mixed in water goes a long way. But test on metal I don't want anyone mad at me.

What a beautiful receiver. The way through spectrum analyzer is super cool, a jump ahead from traditional “peeks”👍. I’m curious to see what’s wrong with it.

[sincerelyyours]

Great job cleaning up those dials! The dials in my Hammarlund HQ-120-X are in good condition but are slightly warped causing some rubbing along the edges. How can I fix that problem without distorting them?

[docholliday]

Great video Buddy. I have the same spectrum analyzer and would love to use it on old radios. Can you elaborate on the "boxes" you are using to impedance match and protect your Rigol Spectrum analyzer? Mr. Carlson has a vid on it but it is for 75 ohms and many requested he help them with this problem. It is a great tool but too expensive to blow the front end just trying things at random. Thanks Doc.
