NTE makes only three things:

Money.

A cross-reference book.

And packaging of remarked components.

This has been their business model all along. Buy parts, scrub the original markings and print a new "NTE" number on it.

They are a marketing company. They do not own a factory.

IF we trust the NTE470 datasheet, there is no other 12 volt HF transistor they could have relabeled, that would match their stated 290 watt collector dissipation.

Question; If DEI 2SC2879 transistors are so bad then why would Texas Star have them in their amplifiers? Isn't this like comparing Chevrolet to Cadillacs?

Got DEI in my DX-500V and they are working perfectly. After the power wire upgrade and cheap fuse removal, I drive it with 30W PEP and am getting a solid 650W out of it and clean as hell. Audio reviews are tremendous. Barely gets warm running at 14.2V idle and pulling to 14.0V on tx

How many amps is it drawing?

Can I ask you gents where you purchase your dei 500v boxes. I've been considering one bit hesitation after hearing so many with the fake toshiba pills.
The Brand New Texas Star amps don't have "fake" Toshiba's They all come with 2SC2879 (DEI) Transistors.
