Guest lime ruined my life Posted January 16, 2006 Report Share Posted January 16, 2006 would it be possible replace a pair of jj tesla kt88's with sovtek kt90's without rebiasing? Quote Link to comment Share on other sites More sharing options...

Jeid Posted January 18, 2006 Report Share Posted January 18, 2006 doubtful, a re-bias would more than likely be required Quote Link to comment Share on other sites More sharing options...
britheguy Posted January 18, 2006 Report Share Posted January 18, 2006 I've heard that it's best to re-bias after every valve replacement. Except on auto re-bias amps Mesa etc.Try asking Mark at Hotrox Quote Link to comment Share on other sites More sharing options...

Jeid Posted January 22, 2006 Report Share Posted January 22, 2006 also depends on your amp. if you have a bias selector switch, then you wouldn't need to get it re-biased, otherwise, yes you would Quote Link to comment Share on other sites More sharing options...
Guest lime ruined my life Posted January 23, 2006 Report Share Posted January 23, 2006 ok, apparently the kt90 is fully interchangable with the kt88 OR 6550.incase anyone stumbles over this in the future.edit: the early kt90 models arn't compatible, but anything post mid 90's should be.
