[sdiy] Dr. Bob speaks on the 904A

[Paul Schreiber]

per phone call:

Q: Were the stock 904As supposed to self-resonate?
A: Well, sure (laughs).

Q: I looked at 6 904As. 3 oscillate and 3 don't. So I wasn't sure.
A: What can I say.......(laughs).

Q: Do you thinks it's a reduction in loop gain due to aging in the 2N3392s?
A: (pause)...Something like that.

Q: Does the Voyager self-resonate?
A: Sure.

Q: The 904As are designed not to resonate below about A440. What about the Voyager?
A:It has a much wider range. I learned a lot in 30yrs what people expect.
