Who works on Texas Star amps?

I have a feeling they know they're insulated as he bought from a retail seller sounds like. If that's so, then TS will rightfully claim they have no control once it leaves their facility. Likewise the reseller which is more likely the responsible party as THEY likely had something to do with selling the return or botched amp on, will claim well I know nothing, better call the manufacturer.
Both parties will do nothing, Eldos out the money, and a POS product was delivered. Sucks Eldo. Sorry brother.
And I'm with Shockwav. There is no way that work was done by anyone remotely familiar with a soldering iron. Some complete hack has been in. That isnt a new amp. It can't be.

Well, John was the Galaxy guy, and I always got a call back or an email of when I could talk to him. If Texas Star sold or is under new management it might be what the issue is. I don't know as rumors fly about ownership.
John has helped me several times in the past on anything I had asked including staying on the phone and guiding me through a repair or troubleshooting issue. Which is one reason I have several Galaxy radios.
At one time I had an issue with a fleabay radio that came to me totally pooched, and full of sand, and Galaxy offered to send me a new radio even though it was not their responsibility. I declined the offer, as I said it was not their problem, I was just looking for suggestions on repairs, and I think they had stopped repairs other than warranty at that time.
I can't imagine something as bad as the AMP you received was even allowed to leave the facility they are made in. Looks like they handed a soldering iron to a child and let them have at it.
 
To answer your questions, I did call, more than once and left a voice mail stating my issue and that I would email. The response came Wednesday via email but it was from Texas star amp repair and Mike Hawkins was who it was from. He stated that if it were him he would ran his iron across that mess and that it had to have been tested before it went out.

@Smokinone
Yes in the past John at galaxy has been great with radios but it seems the amp side of things is nowhere near the same.

It's frustrating as hell but I will fix it, I have to now..

I dunno, it seems like a gray area, but I think the guy who took my money would be the responsible party as it was really DOA. We all know they are in need of a "conversion" to get them to work the way we want, but if it's botched to the point of the way you received it, that could not be done to achieve the expected outcome.
The seller would be my focus, and if paid by other than cash I would dispute the charges as the way it looked it certainly couldn't be used as a "CW Transmitter".

It's great that you have the knowledge to fix the problem, but so many of us aren't that talented.
 
I may ask for some help from you gentlemen. I'm going to repair traces, clean up solder and flux, probably replace that melted up relay and electrolytic that's all toasted on one side. The value of the electrolytic is no longer visible but I'll test it to make sure it's good.

By chance, can anyone tell me what the value of that electrolytic it? In case I need to replace it.

Or used at all in any way.
Heck you don't even know if the transistors are still working by the looks of heated base resistors from your first pic posted. You shouldn't have to fix it unless they say keep it and refund your money.
Smokinone has the right suggestion. Let the seller( who for some reason has not been divulged yet), fight it out with galaxy. Seller probably stocks un-used TS boxes, you don't know.
When you show your credit card company/bank the pictures they will get you your money back and as a bonus, you might not have to return it.
Its a sad situation and I feel for ya man. There's no reason to settle for junk.

The cap is usually a 1000uf 25v

This just turns me the wrong way round... Accepting getting screwed for that kind of money. But I respect the can do attitude.

It's the sideband delay capacitor, 1000uf. We learned to add a 4.7 or 10uf directly across the keying transistor, neg to emitter, positive to the foil pad for the transistor's collector. Makes the keying transistor last a lot longer any time a radio with too much negative modulation drives it.

Got a pic of that here somewhere, maybe?

Thank you!
Maybe you could share those files to the forum information section here, that's valuable info and could really be helpful to us all in the future.

I appreciate you help sir. It's been completely disassembled and I've been working on it in the evenings when I have time. I've repaired a trace, removed, cleaned and reflowed a majority of the components as well as beefed up some things. The circuit boards are night and day different from where we started. Rg316 coax arrived yesterday so that'll be put in there too.

Once I tore it apart I felt committed to the repair and I'm taking the bad experience to learn the circuitry and the build of the beast which is something I do enjoy. Doing this kind of work is somewhat of a mental decompression from stress sort of like how some people enjoy doing puzzles for fun.

Anyhow, I woke up yesterday and to my surprise I had a response from galaxy. Mike said he hadn't seen the picture of the broken trace and that there's no way they ever powered up that amp after assembly and that he would send me a replacement front ppcb.That tells me they aren't a very refined machine over there. The last email I sent had all the photos and some of me expressing my thoughts on the workmanship and quality of the box so I thought for sure I'd get no reply so to get one a week later is surprising.

Soooooo..... I hope to have it all put back together this weekend and I'll share photos as well as let you all know how it works. I haven't done the power wire upgrade but if all works well after initial start up and I decide to keep it then that'll be next. If there's any issues I'll address them and just unload it after that...

More to come
