Any suggestions on new tubes kt88 and do you sell a tube kit ? Also do I need to bias the new tubes if they are like for like, thanks
Welcome to the forum.
We’ve been recommending 6550s for the last couple of years due to the erratic supply of good KT88s.
We sell Sovtek and JJ 6550s currently. Contact support@fryette.com for pricing and availability.
Yes, they should be biased, especially if it has been significant time since the last service.
