CBS240...The supply is +/- 12.5 V rms and currently the output is biased at 1.0A, and running into 8 ohms. I am currently using two 2N3715 (push pull) in a TO-3 package, and fairly happy with the waveforms, and the sound. I am looking to improve the audio performance, and also switch to a TO-3p package for mechanical mounting reasons.
It looks like the FJL4315 would handle even more power and the gain curve is similarly flat, although as you can tell from my little supply, I don't think I will pushing any of these devices to their limits for temperature and power. I'm sure you're right about the price too!
Thanks,
Joel
