Stinks ... yeah . I even had my passwords hidden on it. I remembered my primary Email - cool.
Recovered most either through my primary (email) or with the browser password manager.
Only one to go is PayPal - they scammed my old phone # from me last year for authentication. don't have that
phone anymore !! this is how I lost my Yahoo primary mail. I spoke on the phone with them and they would not help me recover
without paying $$$ for a extended customer service account. I stopped using Yahoo (20 years) and went to
mailfence.com. since I could no longer use my Yahoo (without paying )., I had to initiate Mailfence with my phone.
Mailfence does ... however - allow the use of another email for verification in case you forget the pass.
I just printed my passwords , copied to a thumb and have them hidden on a new SSD (spare).
PITA !!!

We would of been closer if I did better housekeeping. I just updated Spooky/hellraiser schema's (from the forum).
Have the 2 ISP templates and the OPS template done. LOST it all !!
What are your needs ? I'm going to start the mini OST output stage (again). Any "extra needs" ?
PS - just bought a 1TB new SSD (35$) hard drive. I'll keep this 250G one i'm working on now.
I can still update the first post at will ?? Use it as my 3'rd backup
OS
Oh no! That is so much of data and hardwork . I was just thinking when you would be starting a GB and this happened.
Terrible, just damn terrible.
How about data recovery services? Ontrack, Ace data recovery, Gillware ….

I'm quick , I'm using my first post here as my "cloud". I have all the templates and what I already posted as reference.
I predict Friday I will be back to where I was Monday morning.
I might slightly redesign the little OPS to fit MT-200's .... so maybe it will be better.
OS
Ahh , I don't like $$$ services. I'll just buy more thumb drives and SSD's.
What was strange is that I was simulating with LT spice to the failed (mechanical) HDD. Reading and writing to it's large .raw file at the time of failure ?
Perhaps using this present Samsung EVO SSD is better ... it is faster to simulate now ! 120GB just for DIYA stuff , 5 YO SSD , still works perfect.
PS - that was only 1 of 4 HDD's in my main PC , I have 95% blu-ray backup of lost video and I DID NOT lose my MP3/FLAC collection (on my helium 8TB).
I have spare HDD's and bought more. I also really learned a hard lesson - all is good (better).

Sorry for the loss of your data. Hope you will get back in the saddle soon.
Here's one other thought of improvement : R26/27 seem to dissipate a lot of heat for those tiny dimensions. Especially the trimmer might suffer from long-term heating. I think the required value can easily be calculated for a given PSU voltage, so it might be an idea to use two larger fixed-value SMD resistors that can handle the dissipation without a sweat.

100V = 3ma= .3W that's not too hot. I made the pad a 2010 SMD. They are in parallel , so .15W per device. R26/27 = R23/24 on the Hellraiser.
The truly final schema's and simulations are on the first page.
You are right , at a max 90V rails you would need 100K per resistor to trim out 3mA (leds) + 4mA = 7 total for the VAS. You would still be at .5W total.
Edit - try the latest .ASC files. both set for 20Khz / 1V .

Yes , R23 or 26 on both IPS's @ 100K and the trimmer at 70K allow scaling for 80-90V rails.
This will be for the "ARCWELDER" output stage ( 6 pair outputs) !!

Level 2 of the last "OST mini" is coming along good. As soon as I make it , and OCD it .... I will put it on the first post.
I WON'T lose it again !!
As far as design , it was nice to have my previous routing to go by ... now its just anal layout OCD stuff (pretty and "quiet").
OPS driver emitters can go direct to the big semi's through the output bus trace - one jumper to maintain current. Driver emitters
are just .6V away from the output - creepage won't matter. I do this for all traces , consider what runs through it and what run near it.
It did work out with the wolverine , some trace routes will halve THD near the PPM level. It is also cool to make it "pretty" (with purpose").
PS - my SMD creations (level 2) will be "amp porn"... But , perform as such - as well. cool !

For some people, like me for example, it's more productive to learn and design during night then at daytime.
It's just so quiet at night . During the day I had to put this together (below). Wow , but slightly underpowered with just a single pair TO-247's.
Speaker is S12HO KRK with 15KG magnet , box is 25KG Skar audio tuned to either 35 or 25hz (block one port). 400W speaker !
I need more capacitance , at least 10KuF per rail. I have 2 200VA trafo's , 8 outputs. Need power !!!
I ran the HK-680 through it , 20mm Xmax. One song on Youtube had 20hz stuff mixed in .... wow - wind in the room.
Spooky will rock that speaker.

OST-MINI.ZIP is in the first post .... nice and safe !! And on my new SSD + a thumb drive.
I found my old Slewmaster artwork (macro's) and tweaked them. Review the OPS , matches either OPS included with the IPS schema's.
This is the first time (and last) time I will ever lose data !!
Time to do the Spooky and Hellraiser , even prettier than the last ones.

OST-mini - power.zip (posted and safe)to go with the OPS. Uses - https://www.mouser.com/datasheet/2/389/stth25m06-1880665.pdf big TO-200 diodes.
And common fuseholders - https://www.mouser.com/datasheet/2/445/696105003002-3091697.pdf .
And ... just a common pair of 24V zener series regulators instead of just the stupid leds. I use these on that above sub amp followed by lm79L12/78L12
for my filter board. Works good - 8 years.

This is where we (I ) am going.
1. mini OST OPS
2. "arcwelder" big fat OPS ...
3. Power board .
4. Spooky , Hellraiser , Eyesee , Kypton , and a SMD Wolverine.
And , I now know how to code ESP32's and ATmega 328's . creating any protection is simple.
22nd century protection (below). New stuff , software triggering class A with a cell phone ! imagine that !
That's why I added those 24V outputs to the power board. At .5A , 100mA of 5 V, 3,3V and +/- 12v is easy.
NO need for a second trafo.
SMD is another world ! Soooo many better choices , sooo many parts.
