Yes, looks neat ! the 22pF looks like a polystyrene, what are the 100 and 330pf ? Polycarbonate ?
Did you skip the outputcoil ?

22pF is polystyrene, 100pF and 330pF are WIMA FKP2, and I will start without coil.
I added terminal blocks to accommodate larger speaker wire diameter.
Sorry, I changed cap type, now it is okay

As long as you don't use cheap ceramics everything should be fine !
If i remember correct, polystyrene have very good HF-response ?

This type has low dielectric loss even for very high frequencies, and low frequency dependence of capacitance.
I use polystyrene for phono circuits and feedback compensation, also for VAS compensation. They can make a big difference in sound, especially when the original was a ceramic.
You just have to keep them cool around tube stuff.

Art applied to electronics Pavel!... very pretty board

Attachments
Thanks for kind words Carlos,
Yes I took the picture myself, but did not spend much effort. The camera is Canon S50, and image had to be compressed horribly to meet attachment rules here (no more than 100kB, no wider than 1000 pixels).
Photography had been my great hobby in the past, unfortunately I did not have time enough for it after I left school ....

A big round of applause for Pavel.......
honestly, the board was everything professional, how did you do that.
I have been having problems doing my board because of the size and the fine lines on them. I use the lazer direct printing on board before etching and the fine lines could not reproduced well.
Well, I am still on it.

Hi soundbag,
thank you very much, but I am on "professional" side of the board. I design and produce customer-tailored electronic measuring instruments, and the board shown here is a little bit less than standard how to make PCBs. The PCBs are produced in a company who is a PCB manufacturer, they are made from Excellon (drill) and Gerber (photoplotter) files, not by laser printer.
