NOTE:
This project have a some limits in frequency response and
distortion so please
look
the my new design.
This photo show the final chassie but with 2A3 tubes
All the audio transformers used in this project are
Lundahl products and the distributor list is available here
Lundahl is one of the world´s
leading manufacturer of audio transformers used in many professional studio
recording and radio stations so He have a very big experince and all these
products use a custom audio C-core.
I am using a The input stage tube is the Golden Dragon 6SL7.
About passive components types, I don't leave many choices:
Caddock resistances on cathode, ELNA Cerafine capacitors on cathode.
In all my previous projects I have used in the power supply the ELNA
Cerafine capacitors with a very high sonic performances and compact size.
If we skip any economic aspect and no size problem the first components
is a paper in oil capacitor.
In comparation test the paper in oil are better than ELNA Cerafine
or any electrolityc type.
Searching a paper in oil capacitor is very important buy new product
as the Jensen and not an old stock.
About wire forget the teflon ! use only stranded tinned copper wire with pvc isulator and for loudspeakers the same.
A very good quality stranded tinned copper wire could be buy directly from
E-Z-HOOK that carries an extensive line of fine stranded and extra flexible wire.
top performance !
