Hi everyone. I have trouble with a TLD2601A 100 Watts VHF amplifier for a Motorola repeater MSR-2000.
By touching the pot of power control, I lost all the RF power and nothing since. The exciter module is fully functional and put 400mW. The power supply is ok and I found all voltage on RF transistors, I feel that the TX switching is no longer works. I have the service manual for 30W station but nothing on 100Watts. On the left side of the amplifier I have a Molex plug with 4 wires and I don't know what is made for. Maybe somebody on the group has experience with that and can help me? Thank you. Eric
