6c45pi w/CCS

Attached is the schematic for the 300B driver which is a CCS loaded 6C45Pi, note it is running at 220VDC. You can run the 6C45PI with a 1 K plate resistor at aprox 24V and no CCS.

Hi Mads!

Wow! You guys blow me away! Nice report Tyimo!

Thanks!;)

You would have to get smart and cascode etc like ZV9.

Unfortunately I have never seen any cascoded source follower circuit.....

I think it is better to design amps that you can use parts that are already in the thrash box

Yes! But my 6 pieces Lovoltech JFets are in the trash box!:D :D

Would it be possible to use them for a JFet BOZ???????

0,5'C/W each channel @25'C with 2A bias and 22,5V rails is what I use.

PS -I'm leaving town to Grovare, Sweden (near Göteborg) to celebrate my grandmother's 75th bithday at her summer house tonight. I'll be back in business on monday ;) And to buy plenty of cheap SNUS ;) ;)
