(1) Tested RCA 5R4GYB Tube. Date Code 7230. Black plates with a top side O ring getter. The tube number is worn off of the glass. We prefer the versatility and precision of Hickok TV-10 military testers and use them almost exclusively except in rare instances when pinout/socket compatibility is not possible.
