Hallo Purer,

thanks that you share your schematic with us.
As I see this is the Line Stage. Do you have
the complete information on this Preamp?
Phono? Power Supply?

Oops forgot to ask my question... of those two transistors in the right hand corner, which is the BU805 and which is the MPSA42?

Hello,

yes at the right corner is a part of the power supply. The complete power supply is more complex.
There is no heater supply.

As I know the original power supply works with cascaded Fets for each stage.

Maybe purer gives us the whole information or can answer the questions.

hello Purer,

your first schematic looks like a photo from the original manual. It would be good if you scan the complete manual, incl. Phono and Power supply and send it to our e-Mail. Thank you in advance.

Why don`you make your preamp a dc Preamp without the cap?
