Hi all

Just picked up one these amps, and so far im loving it.

Just one question ... is this amp self biasing ??? or does it need manual bias

Just checking as it doesn't seem to say in the manual.

Thanks

ANY tube amps need to adjust bias. Unless you want to take chance to shortened your tube life or if you don't want good tone.

Self Bias is also call "cathode bias" and generaly used in class A amp. These amps need a bias check when you replace power tubes.

The other kind of amp are class AB and have a fixed bias which is a "grid bias" and sometime have a potentiometre to adjust. Need to check bias too.

I hope this help you,
