Any chance someone here has an early A.R.C. R-13 manual? This is not the gray Type-12 set. It is the "first generation" post-war R-13, which is black and has a dial on the front like earlier sets. It is a direct decendent of the WWII R-112 and R-113 receivers. Came in 12- and 24-VDC versions. Need a componant value. Thanks.
