I started to restore a hd130 reverb head .
Someone replaced the output transformer with a non original.
Bought a better replacement.
I connected the primary side but i,m a bit confused about the secondary side
I got yellow 8ohm wich should be connected to the impedance switch
I got green 4 ohm wich should be connected to the lug on the opposite side
Of the impedance switch.
Then i got one lug left on the impedance switch wich should be connected to the speaker output jack
But then i got one purple wire left from the pre amp board and also a black one from the secondary side of the output tranny.
Where should these go?
