New Stasis front end

As usual Mr Pass covers all bases, I wonder if he ever played baseball at college? The great Zen Mod should know.

I think it's more to do with lessons learned with messing around with circuitry hooked up to his flux capacitor.

while some were on the field training muscles, he was on the grandstands, dealing with chicks

which gave him enough xperience, later to pick - best wife

Ah, I see Zen Mod thanks for the inside info. As always, behind every husband there is always a great wife. Mrs. Pass must be the ultimate.

Jill is Papa's Flux Capacitor

Hahahaha

Don't ever take for granted what a flux capacitor can do.

 

[codyt]

1.21 gigawatts is exactly what it can do

 

[2 picoDumbs]

Exactly.
Hahahaha

I notice that you got rid of the asymmetric degeneration resistors, which were used in the input differential amplifier of the original.

Delightful!

Aside from the pinouts, would an OS stage for Stasis look pretty similar to the BA complimentary boards? I have a hard time deciphering the bias circuitry in the schematics.

Or if one used the BA boards as-is, you’d have a Burning Stasis?

 

[Zen Mod]

this one made for bipolars in OS

 

[codyt]

So drive +/- would feed an OS, and the ‘out’ would be your typical single-ended or standalone signal, correct?

 

[Zen Mod]

Q9 is bias generator for bipolar OS and driving modulation for same

everything right from Out badge on FE schm is for voltage biasing of "outer" output transistors ....... Papa just forgot to label "+C" and "-C" on schematic, while they're clearly visible on pcb

print all posted schm in first post an stare at them

 

[codyt]

Ah, perfect. Will do!

I think ZM is referring to a Cascaded Output stage as per the Stasis 2 schematic. As you can see in the photo of Nelson's test jig, all components for that version (C7-C10 and R23-R28) are not loaded. He has even left off the output zobel components R22 and C6 as built and tested.

 

[codyt]

I’ve studied the schematic a bit more and still wrapping my brain around it. This help a lot, thanks!

Wow! Impressive. I love this. Can you send me the details of you build?

OK thanks. I got excited for a second..
