DEF OS is proven as special case , where you see Tokin SIT working good enough on lower Uds
as shown with Singing Bush (common source). there is really beneficiary increasing DS voltage for SIT

Your Mightyness, what's the difference between the two?
35vdc is clearly 35vdc
but how much is 35vdc++? For the case that it should be even merrier

A more serious question: if I intend to build the Schaded version, all the parts of the SIT-version must be used, minus SIT? Or am I just confused?
For the not Schaded MOS only, should C16 and R50 also be ommitted? Otherwise they are just there without contact to other parts (schm says nothing about this two parts for MOS only).
And as always - which one (MOS only or Schaded) do you prefer?
Okay... your very first posting in this thread answers almost everything
Only the question regarding Schaded version stays for me open: all the parts of the SIT-version must be used, minus SIT?
Many thanks!

POST #119 is having pretty much complete info for Babelfish XA252 SET
one thing (you know that ZM is polishing da Turd all the time; if Pa can deal wth Muffs, ZM can with Turds) - zeners (ZD1 and ZD2) in series with precision CCS are changed from 18V to 22V - just to leave even bigger margin to max allowable voltage across LT3092
anyhow, if you have specific question, just shoot

had Lucida Intervalla (regarding mythical LT3092) just yesterday; it seems I'm really going to use most tricky ones for soldering - there is plenty of them on Market, and I was blind for fact while avoiding them as plague (3 cases - one big, easy, one small with normal pins, tricky, third small, full no pins smd, damn tricky) ......
though, not single reason why I didn't started with XA252 kit frenzy
had enough on my plate anyway ........ and it is much more fun making new amps than selling any old one
so, ooomphteentht time, soon

I did the small 8 pin LT3092. After watching a couple of videos of people hand soldering tiny chips I gave it a go. Loads of flux, a little solder and hope it flows. The hardest bit was identifying pin 1 that had a chevron next to it.
ZM,
To make soldering the DFN package a bit less tricky, during pcb layout extend the solder pads slightly so they stick out when the DFN package is in place. This will allow touch up with fine tip solder iron and lots of flux 😉.
Hot plate method also to solder belly pad. There’s 1000’s of those little buggers ready for shipping to you.

tnx! ......no worries, I'm already used to that
in fact, (almost) all smd packages I'm using I already edited (in Eagle library) to have prolonged bare pads
I have warm plate (even if just 70C, believe it or not, sometimes world of difference) and hot-air station, so only obstacle is my eyesight, luckily easily helped with ..... helpers

It´s me again, Mightiness 🙂
I checked Post 119 against the received new schm, and there are some differences, could you please explain it?
- Post 119 schm has in the SIT/Schaded area a 0R (R45) between R44 ans R46, in the received schm is this 0R missing
- Post 119 R50 is 750R, the same in the new schm is stated as "47R or 750R" (and called R51)
- Old schm R6 10k, new schm R6 15k
Many thanks!
