"But two pays and collections of details under them will how much cost" said http://babelfish.altavista.com to me. Didn't tell me any particular

Mr. Professor, english is the main language here but if you have some problems with you could always try Altavista.

A hint to everybody else who want to read the russian forum, use Altavista for this also, works rather good, much better than french

A cost of 1 printed-circuit board without the components is 700 rub. for Russia and 25 Eu. for other countries . I sell only PCBs and don't sell other components for this amplifier

I notice at the right phono connector that you have a "meander" trace. Why is that? Do you have a groundplane on solderside?

A purpose of meander is alignment of the stray capacitance of the input circuits in both channels. Actually it does not influence to sound (I don't hear any difference), but I made it only as decorative element. This PCB has a split groundplane on bottom layer

Good you say it didn't make any difference. 1 cm2 copper on both sides makes a 3 pF cap and you have a trace over a groundplane it become even less.
