This beautiful HQ-170a came to the shop with very low audio. After some careful diagnostics, the culprit revealed itself. Simple repair, but difficult to find. A very nice quality receiver. Live long and prosper.
I have one of these radios in my collection and it is on my to do list Thanks for the tip, wish you were standing over my shoulder guiding me as I restore it!!! You make everything look so easy, sigh, sniff! Thanks again VA6RDR
Hey Terry, great video. Great work. I came up listening to my dad's HQ-105TR. I have great affection for these boat anchors. Looking to get one for my son to listen to. PS -- Love your shirt
This reminds me to always look for the obvious first. This brought back an incident about 5 years ago...customer brought in an old Bogen PA amplifier, and he complained it blew the fuse instantly when turned on. Well, the first thing that came to mind was, shorted output tubes, shorted rectifier tube, filter caps, or output transformer. but after taking the top and bottom cover off the chassis, one of the things I discovered was, the two high voltage secondary leads that went through a hole which lead to the underside of the chassis had sliced insulation and the leads were welded to the chassis. obviously, some clown replaced the PT at one time and failed to replace the rubber grommet where the secondary leads passed through. Luckily, it didn't fry the PT. After removing the shorted leads, I cut & restripped them and soldered them...installed HS tubing, and added a new grommet...problem solved, amplifier was back in service which equaled a happy customer. After many years as a service tech, I learned in my younger years to look for the obvious before spending time on component-level troubleshooting :) Great video! Keep more coming :) Now, chill that Merlot and enjoy the holiday weekend :)
