Thats my kinda sim. Is that what you worked on all weekend

 

[generg]

Baldrick ZM

when you give me full circuit..... I will SIM your future!

 

[Zen Mod]

steady boyz



that's just basic -no input signal - sim

intended for verification of biasing , servo , stability vs. mains fluctuation

it seems stable for all possible (even ! combinations of) +/- PSU voltages , ranging from 10 to 34V (nominal is regular FW PSU , with added 12 neg-neg leg)

edit : what counts is - not do I know how to make a proper sim , but - do I have Preputium made parts ......

SIM-sala-bim, and he was sitting on the pole again!

Ah, Il Bače again.

Dont fall

 

[Zen Mod]

good to have Mighty Moi around , just to prevent ya to drop as boredoomed Dodos

 

[buzzforb]

Yo Pa - I needed prediction for few values for servo circ and level shifter .......

'course plus of it connected to gate , minus to other end , which will drive precious unobtanium

Most important thing for boredoomed dodos.

Your hairdo and shades are Beatles-ish; maybe you were Zen-meditating with Lennon? Expensive shoes. Their soles are vegetable tanned leather [pink due to Fe ]which makes them puncture and cut proof; e.g. like used by the Leather Necks. Will this device have the characteristic Triode-ish Id versus Vds curves?

Exercise in frivolity?

 

[Zen Mod]

good enough

especially special part :

 

[Zen Mod]

..... Will this device have the characteristic Triode-ish Id versus Vds curves?

as I already wrote - that's just mock-up for trying Pass SIT-1* biasing methods

of course that * is triodish

I blame it as 300B with OPT, in one small case

whatever , I can declare that I drew extremelly successful Babelfish SIT-2 schmtc , where Babelfish always means very unnecessary complicated version of Pass simple circuit

Proud ZM

ZM
I remember in an old thread, a discussion about how that common resistor affects things. Does larger R diminish effect?

 

[Zen Mod]

buzz

hard to see a tree from the wood

you already know that - BA3 Bal

you drew it well - leave all values as is

for each amp half everything south from that resistor is just - gnd

 

[generg]

Off topic,

I am sure sitting in the way ZM does may be very good for his back.....

 

[Zen Mod]

yup

everything south from my neck , is just - gnd

 

[jacco vermeulen]

We have been aware for some time that you're short-circuited.

 

[Zen Mod]

in every direction

buzzforb, thanks for the schematic. I am unable to expand it fully; like the SIM schematic of Zen Mod. Do I understand that the gate stopper resistor [a linear device] in the SIM schematic gives the FET linear characteristics?

Great picture Zen Mod. Pine trees and blue sky behind you. Would love to see another one like it this year.

Sorry, guys, for interrupting your "high matter" discussion with my daily question, however :

I am going to use a PSU board from the store and recommended diodes are MBR20200CT, but I guess Nelson recommends MUR3020W in F5T paper. Which ones will suit better for F6?
