27K resistor: AMTRANS have Metal Oxide and Carbon Films. Most probably you recommend Metal Oxide ones, correct? If yes, what about Panasonic ERG-2 (2 watt)? I used them in DIY Nelson Pass amps - they are pretty good and small size too.

I would go for the carbon film.  We will use metal oxide resistors in our products where they don't handle signal current (mostly R2 on C4S boards) or where there may not be other good choices (sometimes for really low value/high power filament dropping resistors).  Since there's a big cap across the 27K resistors, I wouldn't be too concerned about using a metal oxide resistor there, but technically I would consider it a downgrade from the parts we provide.

Resistors are changed. New ones are:
> 47K - Dale CPF3 3W
> 27K - Amtrans AMRT 2W
> 220K - PRP PR9372 1W

This resistors become really hot after an hour of listening. It was absolutely necessary to have more power here. Thank you PB!
