WTB: JBL DX-1 Input/Output Crossover Cards to suit JBL's XPL-200 Speakers
 

After 2 sets of Input/Ouput Cards for JBL's external active DX-1 Low level
network crossover.

The cards and the DX-1 were made for JBL's XPL-200 speakers.

I will accept blank or variants of the input/output cards.

I you have cards you don't want to get rid of, any photos of the low and
high frequency cards would be much appreciated.

Cheers
