Finally fixed the ouput jacks on my Onkyo T-4555 tuner....

I've had this tuner a few years and its got FM, FMHD and XM capabilities. Unfortunately, the board mounted RCA jacks failed in the left channel. I kind of blamed it on the interconnect I was using at the time, but after I (painfully) pulled the board out, I discovered that the metal for the surface mounted RCA jacks was hardly soldered. In fact, the metal seemed to resist any solder application, so hence, the audio problem. So, I replace the jacks with some more traditional types of jacks and soldered wires to the board where the connectors were.

Happy to report that the kind of scary mission was a success. It was to the point that if I screwed things up, it would not be any worse then the then present situation. So I put on the
"big boy" pants and tore things apart. I guess sometimes you have to take risks.

I am disappointed  with the Onkyo brand, as I have had to fix other mechanical things on this tuner. The coax connector became loose, and required some ingenious thinking to get that back to square one. I also noticed that the paint on the cover is coming off. If any of you know me well, I keep my equipment looking as new, but this piece just did not want to cooperate.

Good job.  I had to fix/replace the speaker jacks many moons back on an NAD 2100 amp.  Really can''t complain.  Yes they (the originals) weren't the last work on quality but they lasted over 10 years.  Had to to some minor mods to the chassis.  Had bad solder on an old Marantz SR7300 OSE receiver that led to one of the preamp outs not working (you could hear the loose piece of solder when you picked it up).  I started to take it apart years back and with the stacked boards I decided to just leave it alone (was in a secondary system).  I sold it cheap anyway to a friend and he won't ever use the preamp outs.  I have a bad preamp out on my Onkyo 1008 receiver now (I think it is the left surround) but I got rid of a 3-channel amp and in favor of a monoblock just for the center so I'm just using outboard amplification for the front three channels of the main integrated A/V system and that receiver may just end up in the bedroom (without the need for preamp outs) within the next year.

Except for those audio companies that have their own factories (e.g. Rotel), many of those mass market brands are made in different factories which may have been making a non-audio product the week before on the same line.  I've fixed bad solder joints in a couple of things over the years.  I guess it just comes with the territory of mass market stuff that you will have some of these issues.  Some of the companies have been getting back into audio pieces and while some of the stuff looks really nice, it kind of makes me pause when you can buy nice well made stuff such as is made by many of the sponsors here.
