THE VU METER
The VU meter fitted to the CTM is a dual function meter detailed as follows:
By using the push button selector switch marked "AUDIO / BIAS" the functions are
accessed in the following manner:
1/ "AUDIO" - In audio mode the meter is set to read the audio output of each of the
six power tubes and each can be measured by utilising the rotary selector switch
on the front panel. Whilst playing this is the normal mode of operation of the meter
and the reading obtained will be a direct indication of the power being produced
by each output tube, the meter is calibrated so that when the needle reaches the
start of the red section the power tube being measured will be producing maximum
clean volume.
The switch can be rotated to select any of the power tubes and its relative output
will be indicated on the meter, note that when performing this test you will need to
play at equal volume for each test.
