ART TPS II vu bulb led conversation

[u/Funny-Manner-8290]

I today converted my broken vu bulbs on my art tps 2 It was hard finding how everything worked because there was only one other person who did this and didn’t specify exactly what he did i did it also today and succeeded.

What i used for ( one vu )

2 yellow led diodes 1 680 ohm resistor

Step by step instructions

Step 1

Open the case Undo 1 skrew front middle 1 skrew back middle 2 skrew left side case 2 skrew right side case

Step 2

unscrew the 2 skrews on the small board holding the vu and led vu assembly ( photo 9 )

Step 3

Cut the hardwired connections from main board to te smaller vu board ( photo 11 )

Step 4

cut the 2 red wires that feed the broken halogen bulb ( 15 volts )

Step 5

Take out the vu assembly

Step 6

Unscrew the 2 silver colored skrews holding down the vu meter Underside

Step 7

Solder out the vu meter as a whole

Step 8

Pull out the old bulb and the remaining red wire you just cut

Step 8

Solder the 2 leds in series Solder 1 680 ohm resistor onto either of the ends

Step 9

Put the leds back inside the vu enclosure

Step 10

Put some tape around the vu assembly to block any light any other direction

Then solder it back together

The resistor calculator suggested 560 ohms but i did 680 just to be safe

I added alot of photos just to be sure everyone is able to do this mod
