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?

Please, I could use it too.

 

[Mats J]

isn't that the PS in the upper right hand corner?

 

[Mats J]

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?

Do a search here, this topic has been recently discussed on another thread and the schematics are there provided with various caveats due to their questionable provenance.

The original design has never been published and most schematics have one or more not always obvious errors present.

Guys, please note this thread is 10yrs old, and posting machine readable email addresses on any forum is a bad idea unless you want endless viagra ads and get rich quick scams in your email inbox. 😱 😀
