Replacing light bulb on technics 1210mk2

Replacing light bulb on technics 1210mk2

I bought a few replacement light bulbs to fix my turntables' pop up light from ebay

link:
Technics SL 1200 1210 MK2 MK3 POP UP Target Stylus Light Lamp SFDN122 01E | eBay

I've taken it apart successfully and have followed a third of the instructions by some good folks on youtube who posted up some tutorials on how to change the bulbs, but unfortunately they only offer tutorials for LED replacements and not the original bulb which I bought.

So I've pretty much got the bulb within the pop up shield and I've got both black wires hanging off, I also remember taking off a resistor which was connected to the old broken bulb, I'm unsure which wire goes where.

I've got a soldering iron so I'm prepared to do anything. I just need to make sure I'm doing it right, I've heard some people have had their turntables spark or melt due to bad installations.

There are few minor differences from the LED but I'm not an expert at these things, I hope somebody has some info on this, I've tried looking everywhere but no cigar.

Thanks, much appreciated

It actually takes 5 technicians to do this.
One to hold the lightbulb and 4 to rotate the device.

Why don't you connect the resistor where it was situated on the old bulb and put the new one in ?
Polarity of the cables don't matter as bulbs are fed with AC.

ill be honest, it was 2/3 days ago when i actually attempted this and i've forgotten where sh*t goes.
another troubling thing is that the two wires that come with the bulb are both black and don't indicate anything

Because as said before it doesn't matter how you connect the bulb. it's AC = alternating current. it changes direction 50 / 60 times per second.

The youtube video you mentioned is really bad.

The resistor attaches to the lamp switch. Polarity doesn't matter.
If you got a second deck, just go look at that one

Take a picture of the second one and put it here if you could.

thanks. sorry if the pics couldnt be any more focused, my lens doesn't really take close ups that well.

I'm not sure if i should buy a couple of fresh new resistors but the last resistor i just yanked out because it was soldered in with one of the black wires.

now the resistor is a tad short but it could possibly work, not sure.

If you have a multimeter handy, you can measure the resistance.

HELP PLEASE!
I was replacing the stylus lamp for the regular technics replacement bulb, just by cutting wires and joining them with the new bulb wires, and accidentally the two cables touched and the turntable went off. It is not turning on since then and I can't find the fuse on it, any help? any advice?
Thanks a lot!?

The fuses are located on the power board (smaller pcb) where the power cable is soldered.

Repairing electrics without turning off and unplugging

I've got to replace a couple of these. Had heard it's quite difficult, but from the tutorial posted above it seems fairly straightforward.
