What is CRO? An o'scope?

What is CRO? An o'scope?

As far as I know, this stands for Cathode Ray Oscilloscope

Yeah. I'm just using old school terminology.
I'm old but not as old as brother Generg.
Hehehehe

my brother Generg ......... Old Soul but young in heart

best combo

Absolute gentleman.

Second that ZM ...Generg is all heart.

G....for generous .....G for great guy.....

😀

 

[generg]

Hu, hu, i am no F7,
So don't speak about me......!
I am F70!

🙂)

Don't make me pale in the face.

 

[2 picoDumbs]

Is that 70 in dog years?
Hehehehe

 

[generg]

The only honest honest in your words is the

He,he,He....

🙂 🙂 🙂

70 sheep years!

 

[2 picoDumbs]

hehehehe

 

[generg]

I knew that you are honest!

:--))

 

[CeeVee]

I knew that you are honest!

honestly paleface 😎😎😎

Hi Guys,
Can you please suggest some circuit similar to F7 that can work with Exicon ECX10N20/ECX10P20.
Output required 20watts@8ohm(speaker efficiency 85.5dB at 8 Ohms). I really liked the F7 design because of low components ( actual reason is very limited knowledge in electronics).
Thanks,
Nagu

You might want to check out Cubie 1 through three threads. They use the sk1058 and sj162 laterals, I think. Need to check it.

here, I did it for you. 😉

Cubie - small F5 variant with GR grade JFETs and LatFETs

Cubie2

Cubie3

Then you understand one my concerns for simplicity.

This is the sought of thing I usually say.
Now I feel at least another 3 orders of magnitude dumber than I thought I was.
Hahaha

You can do a circuit with pcf with those devices if you like.

Vssa/Tssa by lazy cat. More like f5 with bjt and vertical mosfets.
