The Johnson Power!

The question itself is: Can I substitute a TIP47 transistor for the MJE340s that Conrad Johnson likes to put in the power supply regulator stages?

Answer: Yes, you can. I tried it, works great. Should consider a TIP48 or better though, the Vce is a little too close to the limit with the TIP47. The TIP50 is even better.

My CJ Preamp is back in business, so my future postings should be a little more on topic, more or less.

Cheers!
