This is a 1501 D. The image is a bit better than the photo of the 81001 above. Compare the two photos to make sure they're the same. You'll need to view the image at 100% to read the values.

thanks for this images they are very good,
how ever Q405 measure 28 ohms from the
{2} together pins, please let me know if
that is right, and D405, D406 are not
in the image, please when posible let me
know if the 2 diodes are just general purpose
diodes.

That's right for Q405. It's a jfet.

I can't locate D405/6. Where are they?

megael9 · 23rd April 2010, 08:27 PM

they are between the 2 1000 mf at 35v caps and the 2 coils.
please let me know of a good place to get the 4 ic`s in circuit.
