Please keep looking Choky, I want to get all faults corrected

Steen

your schmtc make that clear good enough
what I want to say-contrary ro our mate apass-you have perfectly good ground return for gate : R2+ R11 =47K5+1K


gate is referenced to gnd
current through R12 results in voltage for Jfet biasing

same as with triode (now even choky can understand that bloody SS language )

Yes I see, C4 has to connect to the right hand side of R10

Steen

We crossposted, sooo.... Let me think....

Hey Choky and Steen,

All said on my post if you read my lips. As I was writing realized that R11 could also serve as grd reference that’s why I added the last part on the sentence.

Same thing with R10, after writing I had a look at the ZV8 circuit and added Fig 10 as reference

Sorry .. but I still don't get how this cap-multiplier can work?

There's no DC current flowing in the resistors and diode associated with Q3 .. how can Q3 reach a proper bias setting?


Did 'papa' call it a cap-multiplier? shouldn't it be called a technics virtual battery arangment or something like that?

Q3's gate is referenced to ground (via 22oUF cap at gate) only when AC (noise,ripple) came in ;in a meantime Q3 just sits there,eating approx. 4 V of PS voltage
diode is there just for protection

at least this is how I understand this

Thanks Steen, nice words.

Spent some days with my 90 years old good mother in sunny Viña del Mar, wonderful vacations. Also had the chance to see the Queen Marry II sail from port.

Even if all of this is out of topic let me share some pics with all my friends.

Here, my Mother, my wife Betty and yours truly…after some photo crippling to fit...
