Great to see you starting on a Hammarlund. I have an HQ-145 and an HQ-180A. both receive well, but the 145 could use an alignment to improve it's sensitivity. I really love the Hammarlund receivers' Thanks for all the great information. I'm interested in the software you use on your laptop when doing an alignment. Maybe you could talk more about it.
Did you have to align the I.F. cans? or do an RF alignment? I am working the same exact receiver. It is an XA model. same issues you found on resistor and I used the same one you did. I did get the hayseed cap can instead of using caps under the chassis. if you can show how to do a I.F. can alignment with a spectrum analyzer and tracking generator. would be help.
The restoration process hasnt reached the alignment stage yet. Resistors are next. Dial calibration and crystal filter seem out so alignment is likely in the cards. To understand my process, please watch this. th-cam.com/video/yFSJjaKgAJI/w-d-xo.htmlsi=upv9983AdOXYXSld

You know it's a great receiver when they didn't bother to make it too pretty. 😁🇨🇦. Restore!
Thanks!
Thats Great San! Thanks so much!

I'm kinda wondering how the fuse can be in the wrong place when it, or at least mine didn't, have a polarized plug
Once you install a polarized plug, which is a must, fuse placed becomes critical to safety.
@@MikesRadioRepairRestoration yes, just not an error by the designer
Yes it was an error. It was not on the switched lead. A serious safety error.
