Thanks, Rick. Next time Josh and I come through for another trip, we'll definately ask John to give you an hour off for lunch.

Paul, are you suggesting that AP-3's would work better with the phase control shunted by a 10-ohm, 25-watt resistor?

This could be relatively easily retro-fitted in the field, as the resistor could be mounted inside the arm and a couple of short leads soldered to the phase control lines.

Rick, mine did in the CFS application. I don't see why it would not do the same in the A-3. Basically, the only real difference the resistor is in the motor shell of the CFS platter.

Your thoughts are the same as mine for the A-3 modification. I will do that mod with my A-3's in Anacortes when I get a chance, although I have micros in the pay-out heads. Another nice thing about the resistor's presence is that a smaller micro-switch could be used instead of that big heavy one being used now. Remember the old Potts and CFS platters used a 3-amp micro-switch you could get at Radio Shack? They ran for years, until someone had the motor switch in the wrong position during build-up, and burned up the resistor. Then the micro-switch would be toast in just a few "clicks".

However, a good idea would be to try a couple modifications first and see how it goes in the long run.
