[QuadList] Training the Third Generation

Sat Dec 4 11:45:37 CST 2010

Chris,

Thanks for the jolt. Of course that is correct, but I seem to remember other than the biggies on the chassis being bad, perhaps something else on a different part of the machine like one of the big PC boards. It's been a long time. On the remote I mentioned I remember grabing something from one of the plant AVR-2's and racing back to the prison to get the machine back up. Mlaybe one of the guys could help me out.

George

True

That was a way to get out the ohm meter and check all MDA transistors on the rear.  It usually took less than 15 minutes tyo get the machine back on line.

Head MDA
WOW I just had a flashback. When one of the MDA transistors died the head would not start if it was positioned on that phase. Give it a push and away it would go……slow to lock but I think it would play.

George,

Here's my 2 cents.  I would think the 1200's might be the most popular, they are the easiest to fix when they needed fixing.  The AVR-2's worked great when they were working, but to troubleshoot them you had to break out the schematics, scope, etc. and have plenty of room on the floor and no other distractions, like "Air Problems". They also had a minor problem which most people wouldn't even notice till it was too late in the head MDA.  I never liked to have them on remotes.

George Keller

Would you be willing to jot down some of the issues you had with AVR-2's and what your solutions were?

This could be a great help to others to help them get their machines up and running again, or recognize signs of impending problems and act before they become something more than a sign.

Are you interested in doing any maint., maint. training or operator training?

Let me know off-list.  Same request to the list in general.

Thanks,

Ted
