RCA 77V2
#4

IT IS ALIVE!! After 2 years and countless reasons for not finishing it sooner, this 68 year-old unit is up and functioning again!  I replaced all the cracked insulated wire. I had never seen so many out-of tolerance resistors, but surprisingly, every paper cap but one still showed within tolerance. The one cap out of tolerance was labeled RCA! Next up is a Hallicrafters S-41G.  Joe
