You shouldn't have any problem. They're interchangeable.

Giddy up! Replace those fuses (Isoclean or HiFi Tuning) while your changing to the Genalex Gold Lions.

Check with CJ tomorrow to make sure. They seem married to

When I checked with CJ regarding my CJ power amp, I was told that if I used KT88's instead of the 6550's, biasing the amp would be a problem.
