SANGAMO Mica Condensers
doesn't change their capacity
No matter how often the hot soldering iron touches Sangamo Mica Condensers, their capacityremains unchanged. Sangamo condensers are solidly molded in smooth brown bakelite, made without paraffin, and so thoroughly heat and moisture-proof that they can be boiled in water for hours without affecting the capacity. Strong, too; dropping on concrete will not hurt them.
SangamoMica Condensers are the most accurate condensers you can buy, and they stay accurate. In reflex circuits especially, this sustained accuracy helps to make a set reliable, and not as variable as the weather. They are made by a company with a world-wide reputation for building accurate electric meters.
Notice the neatness of these condensers; they harmonize perfectly with other finely finished radio parts and clean-cut workmanship.
Made in all standard capacities with or without resistor clips, and sold at surprisingly reasonable prices for high quality.
