    Why use vacuum tubes to cause distortion when the ICs have extremely low distortion?
    Is it for a guitar fuzz circuit?

    The LM3886 is an excellent amplifier IC. I don't know what the distorting vacuum tube is for.

    Isn't the circuit a stereo amplifier since it has two LM3886 amplifier ICs?
    Then 2 units are you going to use together?

    You showed two or three amplifiers. I don't know which one you are talking about.

    sorry bout that its this one.is 115 vac 330VA 25V+25V ok?i figure its plenty for 8 ohms and for fillamet heater i planned on this one 115VAC 6.3VCT 4A my house current is 110 to 120 spike but i plan to use an IEC Receptacle with 6 amp EMI filter and fuse holder.the the preamp pcb is for for my other guitar amp or head phones havent decided yet Tube 6N2 srpp 6V~9V 30W it actually works well warms it up some what nicely but would be better with better xformer hence the 6.3 vct 4A tranny would you agree?it has onboard power supply dc rectified. man still reading taken a lesson from electrical circuits review i gotta brush up school was25 years ago here i ago again p.s ill keep short next time and tks again...

    The LM3886 produces 50W into 8 ohms with your 25VAC + 25VAC transformer.
