Interested in what you learn, Halo. I just bought this amp, pls post your findings.
Cary Rocket 88R bias setting with EL34 tubes?
Hi All,
I have & enjoy greatly a Cary 88R 'Rocket' tube amp combined with a Cary SLP98P preamp, Wireworld Gold Eclipse cables, & Harbeth 7es-2 speakers.
The amps output tubes are Svetlana (New Sensor) 6550, which are quiet muscular in their presentation. As I'm seeking a more relaxed sound, I've ordered some SED EL34 (St.Petersburg) tubes & was wondering what to bias them at?
The amps owners manual states the amp can use EL34, 6550, KT66, KT77, KT88, or KT90 output tubes, but mentions only one bias setting of 200mA.
Is this the same bias setting for all these power tube types, or does the bias setting vary for each different tube type?
Many thanks in advance for any replies.
Best Regards.
