"PT7" might well be Mission's internal code for a standard device. Even if you can't get actual PT7s but you can get a specification for the transistors (polarity we know, package style we know, bandwidth we can take a good stab at as it's an audio amp; voltage and current ratings and hFE {gain} we need) then it might be possible to locate a suitable equivalent.

I haven't got a Mission Cyrus myself; but I have fixed a few amps with S/C power trannies, and I'm sure at least one other forum member has one.
