Last DX 500 was purchased 4/18/2018. I would not hesitate to purchase another one from them today. In fact I’m considering the DX350 with toshiba’s.
Ok thank you. I guess its good then. It was only one, and I searched all their reviews. Finally. Feel better now that Im getting a 500 thats a 500 LOL. My other one although was like 15 years old and did great, as I was told here and elsewhere when it blew it was a DX400 kinda converted to a DX500. Tax time im getting the 1600 before they disappear too.

I think the LDMOS amplifiers will eventually take over as they are much less complicated to build and they pump out huge power. Also they run at around 50V so switchmode power supplies are also much cheaper than trying to make a huge 13.8V beast that runs at several hundred amps.
I noticed that Copper has two different listings for the Texas Star 350.

If they actually found some NOS units sitting around with Toshiba finals that is not a bad price really for 349. Years ago they used to charge extra to convert them, after reading this thread it appears they ship converted for the listed price. Not bad.

If the cheaper one has DEI transistors run the other way.
They don't specify brand in the cheaper one.
For the difference in quality, the higher price is a bargain.
So long as you don't key it into a broken coax or a mobile antenna with no real ground.

Can't even see what the numbers are on that mosfet. Just know it is pretty and I will deal with the 50v to make it run. Kop you are the tempter!
I noticed this a while ago...after thinking on it, I suspect it’s probably an artifact on their site.
Someone just needs to order one and see...haha.
Maybe not perfect, but a DX350 does just about everything I need in an amplifier.
they added the Toshiba option on there page in the spring if I recall. So maybe. That or they add in Toshibas like Jokerman does. And yes I confirmed with them that they are still ready to go "for hobby or experiment"
Maybe my thought process isn’t the best, but I think expectations have to be set differently with the DEIs or HGs. I figure with a modest drive level they stand a much better chance of making for the long(er) haul. I see 350-400 watts PEP from my DX500, and that’s enough for me. It takes very little drive to get there...substantially lower than what I usually read posted in various places. Maybe I’ll still smoke them babying them...only time will tell.
This is not to say I wouldn’t buy the Toshibas, or pay more for them...I absolutely would.
