The arrows labeled "input transducer" and "output transducer" confuses me
which is the path of the signal ? In which sense is connectred the reverb "Tank"
THANKS
K
EDIT: Seems that the "input transducer" is to be connected to the input of the Tank, but, if so, the output of the Tank is connected to the "output transducer" point and follows to the rest of the amp without any amplification ???

The guitar signal from V1A or V1B splits. One path (call it dry or normal)goes thru cathode follower V4A, normal level control, and mixing resistor R17 to the output jack. The other path (call it reverb or wet) goes thru V3A and V3b and is cap coupled to the input of the reverb tank. The output of the reverb tank goes thru C14 and mixing resistor R18 to be combined with the dry or normal signal.

That's right. Remember we're talking about small instrument signal levels. Vox must have figured they didn't need to boost the wet signal with a typical recovery stage such as found in the Fender 6G15.

Ciao Steve
Grazie
So the path is
[V1a or V1b (or both)] > [R3 or R4 (or both) mix resistors] > V3a > V3b > Tank > [R18 mix resistor] > OUTPUT
and, in parallel
[V1a or V1b (or both)] > [R3 or R4 (or both) mix resistors] > V4a > [R17 mix resistor] > OUTPUT
and the unit is to be considered as designed to be used in front of the amp, not between PreAmp and PowerAmp
correct ?
