Where do I put Variable Resistors on Thunderbirds Classic?

[JSpirtos]

I can see that the top two speakers carry two wires each and that these two wire clips (left = 2 wires, right = 2 wires) attach into a mini-circuit board. From the bottom of that circuit board a fat clip of four wires (blue) feeds through the back near the volume control switches (pretty much useless). Next to that clip there's an identical red clip of wires leading to the bottom two speakers. I've unplugged these sets of blue and red wire and have determined that there are speaker wires.

Now my question is which wires do I cut to place variable resistors on? Do I do two per clip, placing one on and skipping over?

(x = resistor soldered wires, O = plain wire)

Is there a number combination between those usless switches I'm missing?

For Thunderbirds in the Fuji 'GearShock' frame, I usually put the volume controls in the two outside wires of each connector and leave the middle two intact. ie a pair of controls on the outermost red wires from one connector, and another pair on the outermost blue wires of the other connector.

ill second that dave rob i played about with thunderbirds for a long time it was my base for crule experiments when i was origonaly trying to unmderstand pachinko and its workings

You suggest I should do:

Red Wires: XOOX
(x = resistor soldered wires, O = plain wire)

Blue Wires: XOOX
(x = resistor soldered wires, O = plain wire)

Is this correct?

BTW I've notice some of the inner LED lights flickering (especially the right) or trying to complete a rainbow of colors that looks a little off (especially the left). This is going on with the top three rows encircling the T2. Is this usual or a sign that they're going bad? Are they a easy fix? Would I unscrew from the front (removing art) to get to it or go through the back?

I know this is an older machine so I know there might be some up keep though is this usual?

Thanks for your help.
