Does anyone have a service manual for this rig? I
downloaded two off the web and neither has the schematic for the RF board with the voltage readings I need! 73, Roger -- Remove tilde (~) to reply Remember the USS Liberty (AGTR-5) http://ussliberty.org/ |

What is the problem with this TS-930 ? ?
I just repaired one of these heavy solid-state boatanchors. And I need the service manual also, but have most of the schematics. I replaced the RF PA drivers ( NTE236 ), power supply pass transistors ( 2N3771 ), re-worked the cooling fan circuits. Remember the USS Liberty (AGTR-5)http://ussliberty.org/ |

I went through similar replacing the RF PA drivers about 15 years ago. One
thing to watch with the PA circuit board is the holes that are plated to connect the foil on one side to the foil on the other side. The plating may fail resulting in a bad connection. This happened with my TS-930 with the bias circuit of the drivers which resulted in failure of the drivers. A small wire through each hole that is soldered on both sides has kept my TS-930 problem free since. wrote in message ups.com... What is the problem with this TS-930 ? ?
