I think most had the 1969's but the 2312 was considered a slight upgrade back in the day. At some point they would probably use either depending on what parts they had available that day.

Yes, any of the older blue face Cobra 250 350 and 450 xl models are great for SSB use.

That is an excellent old school AB amp with filtering. If you don’t want it just PM me. And right now HG makes a drop in replacement for that final. If one were to blow I would put a matched quad often HG in and sell the others.

Maybe you missed this post he made. His power supply is fine. "Yes Sir, I have a 100 Amp Power Max power supply, I've never pulled more than 45 amps and I don't want to exceed 55 if I can help it."

The talkback control is on the top just to the right of the name Stryker, it's the "mon" control.. Here is what Stryker says about their talkback control. Should be pretty simple. Variable Talk Back ControlThe infamous talk back squeal is virtually eliminated with our independently controlled...

With Carl built you can request a class B bias if you plan on doing SSB.

A local guy has been running a Quad 6 for about a month now, probably the best he has ever sounded. He has had a 2950, Galaxy 86v, and a Magnum S-45 HP. We talk mostly SSB, he loves it.

I would say that radio was born a Uniden Grant xl. Seems like a lot of work but maybe the front face got damaged beyond repair at some point and they had a parts cobra available. Who knows really

What’s the history of the radio as in any mods tunes or final swaps? How are you powering it? If it has a tiny power cord you might be starving it.

I am old school and really like my Astron 70m and 35m. If I was going to get something else I would get a Mega Watt, several locals have them and they work great.

They should all be good for that. There are probably several other good builders out there, I just listed three off the top of my head.

Yea looks like they are down to2290’s https://www.rfparts.com/catalogsearch/result/?q=2sc2290

OMG I thought that rocket box crap finally went away. For what they want for those on eBay no thanks.

At this point there is no way I would pay 505 bucks for a new Texas Star 500. Your best bet is to contact Carl built, hopper built, 307 amps, or another builder and have them make you an amp. Yes it will have 4 HG2879’s but it will be just fine. Just my opinion.

Interesting, it’s a 1x4 transistor amp but the model name is Palomar 200. What finals are in that? Glad you got it back up and running.

I would not assume you have a bad final, these radio's are getting up in age. Might just need a good cleaning of all controls and re-check the alignment. Some times the VR pots can go bad as well. After that might be time for a re-cap. The old 1969 finals are very robust compared to new mosfets...

For decades the DX350 and 350 HDV are all 2 pill amplifiers with 2879 finals. They are what I have heard people say is a passive class AB that when heated up drifts into more of a class B operation. Some of the older models before they were called Texas Star said Bi-Lateral on them. If the...

I think this exact topic came up before. At this point some of these small plastic hard to find parts might have to be 3d printed.

You do realize this was 8 years ago, and the post just above yours says SOLD to Eastside. That means a forum member named Eastside bought it.
