Hi MIKET!

Could you post your CCS loaded 6C45 schematic? I am looking for a good tube pre for my SEWA.

Default 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.

Thanks MIKET!

What do you think, is it not too weak to drive a Mosfet?
Has it +/-20V out put? (on +24V supply)

Hello Tyimo,


ne haragudj, hogy ilyen csacsi kérdéssel zavarlak, de szeretném megtudni, egész véleletlenül nem Te vagy Németh Sándor, aki a Vasvári Pál gimnázium sporttagozatos osztályában érettségizett?

I know a few languages but no Hungarian, as most of the members I presume. Could you please translate?

Hi Hugo!

Sorry, Marietta asked an off topic question about Who is behind my nickname... Nothing to do with HI-FI

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!

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

BOZ is with a mosfet. For a preamp, there are better JFET alternatives.
