124.37 main/standby transmitters released to maintenance. 124.37 buec transmitter was reported by numerous aircraft as muffled. I was having to repeat about every 4TH transmission. Went to workload frequency 123.72. The transmitter was functioning better than 124.37, but the receiver was extremely staticky on both main and standby. At the time of occurrence, I had approximately 15 aircraft on frequency with about 1/2 of those aircraft deviating for WX.
