I just spoke with Chris Johnson at the Parts Connexion regarding the recommended tubes for the Power 3's. Chris was president of SFI and knows the product better than anyone. He strongly suggested the Svetlana KT88 tube as the best option. He said the 6550 variations do not sound as good on these amps as the KT88's due to the higher plate voltage. He is sending me new tubes and some replacement resistors. I would suggest that anyone looking to retube an SFI product contact him.
Svetlana KT88 VS EH6550
Am needing to retube my SF Power 3 SE's. It came with Svetlana KT88's which do sound good but I have heard that the EH6550 tubes are supposed to be very good as well as more reliable. (One of my KT88's just blew a resistor)
Any feedback on the comparison of these tubes will be appreciated.
