Hey everybody,

 

Anyone know if the the newer Sunn 1200s heads are fixed-bias in the preamp stage (aka will I have to re-bias new tubes after I put them in)?

 

Many thanks,

you don't have to rebias preamp tubes.

iirc the power tubes have an external bias pot. so it will have to be rebiased when you put in new power tubes.

No, you don't have to rebias anything.

 

The Sunn he's talking about doesn't have any power tubes.;)
