Is anyone here still available to help me convert my 3m transparency maker model 4550. I am not a guru like anyone here but I do follow instructions very well.

I need to replace my bulb and convert it to 12 amps. I have read through the post and have copied all the links for the parts bulb, resistor. I can get all of them in hand I just need some step by step instructions. Pictures or video and in lamens terms. Lol

I am pretty good with wiring and this doesn't seem to hard can I get any help PLEASE... they want a little over $300 with shipping for repairs.

Also I found this it's a 15 amp bulb

Didn't anyone see this or I am confused because I wouldn't have to change anything.
