Check the simple things. Assuming the Astron is fine check the radio power cord, fuse, and connection points. Maybe try a different power cord. After that it would have to be in the radio. Loose connection, bad solder joint, or a failing component.
Wow here we go again lol. Click on this thread and read post number 8 from Captain Kilowatt. That says it all really.

I second this. Same thing happened earlier this year to my 991a, they had it back in right at 3 weeks total time. And their labor rate was about 40 an hour cheaper then Yaesu in CA.
I think the cheap switching mosfets were decided on by Ranger and Galaxy to save a buck or two. The radio world was forced to deal with the results. I think any of the new Ranger products would be much better radio's if they used mosfets designed for that application.
I recently had to have...
If you like old school built like a sherman tank go Astron. If you prefer newer style lighter weight then MegaWatt. Make sure you buy the MegaWatt direct, there are chinese knock offs out there.
So I ended up getting a Diamond x300a. So far mounted on 20 feet of mast pipe it performs excellent. SWR is good for 2m, 70c, and murs 1-3. I have not tested yet on a GMRS channel. Waiting for a nano vna.

The 2312 is a stronger final then a 1969. The 2995DX never had dual driver finals. The reason the board has the slots for another final is that board is probably also used in the 2950 that did at that time have dual finals. Here is some good stuff for this radio...
You do have a 2995DX correct? The 2166 and 2312 are your drivers, the finals in that radio are a pair of Toshiba 2290’s. Those are 80 watt finals. There is no reason to mess with the drivers, you should be getting around 150 watts from that radio.
Bingo, that's what I would buy. How much is it worth broken? If you like the radio and plan on using it then might as well fix it with the correct final.
The 667 can be a cranky beast when overdriven, and it will run hot. Best two upgrades are larger feed wire and add a fan. Don't be surprised if the right AM input dead key ends up being 1 watt or less.
For the PEP input on SSB you can use the law of diminishing returns. If say 22 watts PEP gives...
Both those radio's have an RF power control, turn the drive down. For SSB use I would start both radio's at 8-10 watts PEP and see what the Max power is out of the Texas Star. Then you can adjust up from there. Probably won't need more then 10-20 watts on SSB. Should sounds great. If you really...
Nothing is failing that’s what happens when things get hot. Maybe add a fan kit or try to come up with a plan to cool the radio down. You could also consider a TCXO circuit/mod.
If you click on the third picture you can see the plug it comes with. They are designed to plug into the back of a radio that has that style port already there. A tech might be able to do a hard wire in, not sure. That said this post is from 2013 and he marked them sold.
