help with transformer volume control

[Wang1]

i built a tvc using 2 sowter 9395 and 2 elma 04-1133 24 position switches, i wired as per the attached sketch, however i think ive made a basic error as i get no output.

can someone give me some guidance with the wiring.

I have used the orange +6db primary tap as the signal input from RCA
Primary red is going to the RCA earth in tab
secondary grey is going to the RCA earth out tab
all the secondaries are going to the switch starting blue/yellow 0db connected to the switch tab when the switch is rotated to the extreme anticlockwise (ie zero volume).
the centre switch tab is going to the RCA signal out

thanks

i think i answered my own question, 0db is max volume, not minimum and should be connected to the switch tab when the switch is rotated to the extreme clockwise (ie max volume).


is that correct?
