Found some schematics that use them as well.

Check out this Cross ref PDF

The Datasheet for BD708 is also on my Datasheet Website. Free membership Required.

Hmm didn't think about that.

Hmm, I think you become light if you break that barrier.

I will look for the original but for now here is the replacement datasheet. NTE 98 or ECG98

The diodes are for spike protection to prevent the transistors from burning when the field colapses in the transformer windings. If you look at a good circuit involving a relay you will see a protection diode across the coil for this reason.

Mine had a swivel wheel on the back to make it stand up. To control left and right all you had to do is hit the switch and it would put on the break for one wheel. This would turn the lawn mower. If you put on the left break it turns right if you put on the right break it turns left.

And here is a Schematic from a Pyramid PB300 Amplifier.

hey, i am having a problem with my power amplifier, it's a 50w PA with audio mixer. I am quite desperate now, i have tried to lessen the humming, indeed it is quite less, but my proff wants no humming at all....what shall i do? please help me out?
thank you very much.
Look for any wires that go in to the amplifier. If one shield wire is broken there will be a hum. Also a bad mic will cause a hum. If that does not work then you should look at the capacitors in the power supply section of the amplifier. Also You could spray the controls with some contact cleaner. ( only Use contact cleaner designed for this! If you don't it will ruin the controls for good!) -
ORCAD And PS or Post Script Files
What are they and what do I do with these type of files?
I downloaded a schematic but, I can't view it. -
MP I'm almost half way there and catching up to you!

ARE YOU READY FOR THIS!

Exactly what are you doing with this little circuit?
I may have an alternate Idea that will do the same job. -
Why make a mountain out of a mole hill just try the easy ones I posted. You can get most of the parts out of an old Transistor Radio or anything that is junk. Free sounds better to me. Or you can even use a Photo Cell.

I just don't like anything that is static sensitive. I tried repairing many Amplifiers with MOSFETs and I think they are junk.

This is the same site. Look at the Knowlege Base lots of good stuf there Lower Left. http://www.carstereo.com/
