Tube Preamps

Conrad-Johnson's tape-input and tape-recorder circuitry is shown in fig.1, with heavy lines tracing one of the two signal routes by which a tape recorder's output can get back to its input.

Fig.2 is an alternative switching method, which would require only one additional set of ganged contacts on the Record switch. This would offer all the flexibility of C-J's present configuration, without the risk of potentially destructive oscillation. Its only limitation would be the inability to record from other sources (CD, Tuner) onto Tape 2.—J. Gordon Holt
