Laser pickup needed
 
I need a new laser for a repair, Sanyo SF-90 (5/6wire) but cannot find one anywhere, does anyone have one?
Also can anyone tell me if the SF-91 (5/6wire) is interchagable? There are plenty of SF-90 (6/6 and 6/8 wires) around is there any way i can make these work?

Cheers George

Hi George,

What CD player do you have that uses the Sanyo SF90 5/6 Wire?

John, I could'nt post before did you get my email?
Also you seem to know these lasers, can you tell me is the mini trimpot that is on the back of unit itself, is this the power output of the laser? as i tweaked it up clockwise about 10 degrees and it did'nt help with the sporatic ticking i was getting on some discs so i set it back again to the original spot.

Cheers George

George,

I check which Sanyo heads I have, sorry they are Sanyo SF-91 (5/6wire). Even with the SF91 (Later head?) tracking performance is very poor - with great problems to read the outer tracks on longer playing disks.

Not sure if SF90 can be replaced with SF91 - do you want me to send you pictures of the SF91 so you can compare physical construction?

Your correct - the pot on the Laser head Assy. adjusts the Laser power.

Thanks John, yes I'd like the pics thanks, because these are available quite cheap too, hope the sf91 will do the job.
