Visit to the WCUG transmitter site in Lumpkin, GA. Original plan of visit was to replace permanent capacitors in place of a temporarily installed capacitor in the power supply section, replace two damaged bleeder resistors, replace some of the front panel meters, and possibly replace a suspect choke/inductor assembly.
On arrival and inspection of the transmitter, we discovered severe damage to one of the AC supply lines inside the transmitter. It had very obviously overheated. We also found that the suspect inductor/choke subassembly had also severely overheated. We temporarily repaired the AC supply line and installed a replacement inductor/choke. We’re holding off on the permanent capacitor replacement because it was determined that a different value capacitor should improve the power supply and transmitter performance, in turn preventing further wiring and component damage.
We will be going back to the site to perform further repairs soon, but have to acquire some replacement parts first.
