Hello,
Can anyone point me in the direction of a simple tube oscillator, preferably with a 12AU7, for mixing into the signal for recording onto audio tape? Something in the 150kHz range AND preferably made with components that aren't unobtainable. The only one I've found uses a choke or transformer that has no specs.
I'm not sure of what voltage it needs to be printing at, is that crucial?
Sounds pretty specific now that I see it written down, but this has to have been common practice at one point.
Thank for any info you might have.
