HI
I am about to build a twin line amp card from Ian.
Could someone explain me "basically" how is the card powered. sorry for those basic question...
I then need a 12volt power AND a 250volt DC right ?
the card use 12AX7 and 6922 tubes.
Could you explain basically what power serve what ?  (heating and ?)
Does anybody would have a basic schematics to could be used with those type of card ?
Another question : does the quality of the heater supply and the rest has a effect on the sound quality ?
thanks a lot !  ;D ;D ;D
