Re: ar 88
Hello,
Raytheon valves have got a good reputation all over the US. I have got some in several devices such as a RT-66/GRC. I have got no Raytheon 5Y3GT (= glass tiny) but a Raytheon 5R4WGB ( aka bullet proof rectifier). Regards, Joe |

Re: RCA AR88 Comms Receiver.
JAN stands for (United States) Joint Army/Navy stock, I don't know what sort of approval criteria they applied back then but they wouldn't have accepted any old rubbish.

Re: RCA AR88 Comms Receiver.
Raytheon valves are generally excellent. The JAN verions are "more excellenter ".
If it is NIB ( new in box ) I wouldnt hesitate. Joe |

Re: RCA AR88 Comms Receiver.
Raytheon are still on the go, making things which go "whoosh....Bang" As seen on TV!
Their valves were made to good standards and have stood the test of time. Company founded by Vannevar Bush. They have a plant near here in Glenrothes and are opening a new facility in the old Jabil building in Livingston. https://en.wikipedia.org/wiki/Vannevar_Bush David
