Geoff -
That statement is included in just about every Drake manual, just by
substituting the model in question.
That said, there definitely ARE places in ALL of this gear where a circuit can be made to work with
a lead in one position, but NOT in another position, even though electrically the circuit is
correct. This is typically a factor in circuits with very low value capacitors involved,
neutralization and Carrier Oscillator balance for example. Other cases may involve very high
impedance circuits where unwanted signals or feedback can be coupled from one area to another via a
wire lead. The AVC, detector and audio stages are examples of this kind of problem.

TNX to all for responding - this is my first SPR-4, so all comments are welcome!
Here's the actual quote, from page 19 of the manual:
"CARE SHOULD BE TAKEN NOT TO DISTURB THE LEAD
DRESS IN THE SPR-4 SINCE THIS. IS CRITICAL IN
SEVERAL CIRCUITS."
