These are the older versions p/n MJE350STU: https://www.mouser.com/datasheet/2/308/MJE350_D-1811352.pdf.
This has no metal tab (collector), but it is still E-C-B.

The series on MOSFET amp projects ends with the lateral "EXICON6" amp. EXICON1 and 2 are posted, EXICON3 and 4 are done testing/write-ups, and EXICON5 and 6 are in the works. EXICON5 is a transistor salad variety—interesting if it works. The Vertical MOSFET project starts off with Projects 1 and 2, but I decided to start the series with the laterals. There are more than a dozen projects on the website that are using verticals, mostly with HEXFETs or QFETs.
I enjoy using a "presentation style video" with animations and fancy stuff on current or updated projects on YouTube. But the website will stay going forward.
Thanks.
Thanks much. I put the locations of Q1 and Q3 back to there original locations...

I don't know if you can still buy MJE350STU/MJE340STU. Do with whatever you feel comfortable with your design.
Thanks.
Thanks.
MJE350STU/MJE340STU
Mouser has MJE350/MJE340 and MJE350G/MJE340G
Is it important that these have the STU on the part number?

Function vice they appear to be the same, different packages though. Both are ECB but no info on the pin distance on the TO-225 package but should be close locking at the drawing.

Not necessarily. When I made the PCB layout, it's practical to mount both of them together on a single heatsink.

Just for fun, laughs!!!
Retirement in effect!!! After many years of finishing work!!!
Starting construction of project #63, my version. Yes, yes!!!
Pictures of the design from EG to AD!
Bye, bye.

The website is in suspended mode until further notice. The @buildaudioamps YouTube channel is ok. More projects are coming up for this channel.
Contact info for BuildAudioAmps.com is still the same and works. Sorry for the inconvenience. Thanks.

"Rebuild" is more of an appropriate word, but "withdrawal"—nah, I've enjoyed building amps ever since; it's too late to withdraw.
I think I concluded the RIAA preamp series with "like a broken record"—BAA keeps on building amps. Thanks.
