Has anyone had a laser replaced in a Audio Research CD-3 MKII

If you want to pay extra, get the genuine Philips ones, I've used the clones and never had a problem with them.

Like I said before are you this guy? If so then you can do it

" If you have patience, are handy using tools and have a bit of electrical skills, you can do it your self, in a couple of hours."

If not then pay someone who is. Not at AR rates

Cheers George

George:     You have been a lot of help on this........I am the tube amplifier builder in Idaho..........Thanks    W

autospec: 
Guessing you're way ahead of the curve on proper workstation grounding & hopefully the laser will also include a precaution note but they can be finicky buggers if you're not careful, especially for the desoldering.

If you’ve built amps then you’ll be fine, just take pics before each dismantling step, so you then know what went where, there no adjusting, measuring, calibrating to be done, basically "plug and go".

2 Channel:    This laser seems to plug in , with out any soldering....I put a read out in one of those CD's and I can tell that's changing a motherboard .......About 40 tiny-tiny pins.......but nobody said it was easy...........I ordered a NOS laser last week and now the guy tells me its one of two type............He's the guy selling it, you would think he would know......But he doesn't, so I'll order one from someone else....Right now the world is in stress......I hope we all survive it.....W
