baaaaad ........
......... Papa !!
in that case - I'll stick with 211 , or RL12P35
Ehh, as far as I know 2x matched pair of new WE 300B would be around 1700USD
But at least the SS devices are more reliable
It would be nicer if price compares to ordinary 300B
But again, why not, if thats what it takes, just hope they dont blow 😀

Not enough volume for any manufacturer to experience glee.
In this case the cost is mostly R&D for probably one time run.

I don't suppose you have planned to spread the cost out amongst your faithfull followers? 😀
Mr. Pass,
I've always wondered how much better a FET designed for audio applications would sound.
Have you been able to work with the manufacturers towards this goal?
If so, what was/is the process like? Interesting stuff!

Because of their intended use, not in class A amps, I always though we had to deal with typical cost and production issues like the package vs. die size and had to settle for whatever Rthjc resulted. Mr. Pass can probably improve that situation by going to a TO-264 package. Or even bigger 😀
Most of the improvements sought after today are for lower Rdson and charge (Capacitance) reduction. Real estate is another consideration. Most all these output devices we play with are for SMPs and motor controller functions of some sort. I suppose there is room to go in other directions but, I havent been involved with any of that 😱
Tell us more please

How about the Toshiba 2sj201/2sk1530 sets? They were specifically designed as complementary audio outputs. 200v 12 amp ratings on both. I built many amps with them and thought they sounded great. Never had any failures even when abusing the heck out of them. Price was not bad at the time, about $6.00 each if you bought 25 or more.
Still have a box of them somewhere, may have to build something with them.
