schematic

Is it possible to see a schematic and a Bom ?

the schemaic is here :

and bom:

 

[oz7aff]

BOM means Bill off Materials, also a list of the components that are used.

Is the transistors paired in any ways ?

Do you supply it with +27VDC and -9VDC ?

2n2222

i try also the 2n2222 instead bc109 and the preamplifier work very well .
I use a pair of lm317 in the psu to get +27v and -9v. from a separate secondary transformer.
