You may want to try the following frequencies: 112, 120, 773, 826, 827, 835, 4152Hz
Also the general
parasite freq's might be of help: 10000, 5000, 4412, 2720, 2400, 2112, 1864, 1550, 880, 854, 800, 784, 751, 732, 728, 712, 688, 651, 644, 524, 465, 442, 422, 334, 240, 152, 128, 125, 120, 112, 96, 72, 64, 20Hz
The Clark frequency listed is not in Hz but kHz, so you'll want to add three 0's and divide by 512 to get a frequency that you can use on most Rife-type machines.
Good luck to you!
