2. The intermediate metal contact fixing plate does not leave enough space below the front panel for the potentiometer body.
The solution is to use XACB or XACM boxes with ZB5AD912 (6mm potentiometer shaft)or ZB5AD922(6.35mm,1/4" shaft).
It is necessary for the user to supply the potentiometer as it is not supplied with the heads. The potentiometer should be 2.2K Ohm linear, with a shaft length of 45 to 50mm. A rating of 2 Watts is recommended for VSD applications though 1/2 Watts or more should be fine and will be much more compact.
