Look first at the output transistors. Those are the most likelt defective parts. Due to the odd design of the output section, Crown amps are difficult to repair. If you get lucky, only the outputs are smoked. Also, make sure that you change all of hte transistors for the channel that has a bad one.

Frequency Response
(-20dB recording)
Chrome tape 40-15000Hz (±3dB)
Normal tape 40-14000Hz (±3dB)
(0dB recording)
Chrome tape 40-8000Hz (±3dB)
Normal tape 40-8000Hz (±3dB)
Imagine what its response at, say, 30000Hz might be. That's what doubling the playback speed would demand from the head and electronics. It ain't hi-fi anymore.
