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.

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.

Perry,
Your right They are the ES2D's for locations D405 and D406 Just checked in the amp i have sitting here

All this Inf has been grate, My final question
I hope, Is, were can I buy Car amp parts?

thanks for all your replies, I still need one more thing to ask, Diode
Location # D404 which is Zener Diode is burnt out & don't know its value.
Can you please let me know its Voltage value, thanks in advance.

after replacing most of the component
oround this circuit, including all 4 ic`s, Im still
having problems, every time I apply power
to this unit, Q404. goes on fire, any sugestion?
and if any one have an schemattic of this section,
or at list let me know how to troubleshoot this section
will be very well apreciated. thanks in advance.
