I'm installing 3x vac relay's into an amplifier. (Input, output, and cut off bias). Coils are available for both 12 vdc ( 80 ohms)....and also 26.5 vdc ( 335 ohms). The amp has to be able to handle a

Same here... 73, Roy  K6XK Had a NC contact fail on a RJ1A. 73, Jim W7RY What is the 'normal'  failure mode for a vac relay ?   Is it the  coil that goes open, or does the armature inside  bind up, a

Me also. Ive had one coil failure caused by my clumsy effort to clean a coil terminal, and one stuck NC contact, likely caused by my trying to switch a DC voltAge (the RJ1A is intended for RF switchi
