My valiant has had the fixed loading caps replaced with the typical sangamo type transmitting micas which are commonly seen... these are about 1/4 inch thick, and measure about 1.25 inches on a side, with solder tabs comming out of thier shapely molded brown bodies. These seem to work just fine. These caps are commonly found with working voltages of 1000 to 3000 volts. In the values required. Larry
