    It's an Amperite thermal time-delay relay. I've used them in the Southgate rigs since the Type 5.

    What is the exact Amperite part number from the manual?

    In what mode? (Remember, the SR-2000 is from the days when ham rigs were rated by DC input, not RF output).

    Yes, it runs a pair of 8122s - but what power the tank components and power supply will do is a different issue.

    For more than you probably want to know about Amperite thermal time-delay relays, see QST for May, 1995, page 84 (Hints and Kinks).

    If it has a 115 volt heater, 90 second delay, normally open contact and in 9 pin miniature, the Amperite part number would be 115NO90T

    Thank you for that number. The number isn't in the Hallicrafters manual, which is why I posted
    this thread. Now I just need to find one somewhere!

    I see RF PARTS has them for $50! OUCH! That hurts! Will look around and see if any are available anywhere cheaper

    I am quite aware of the rating system. I actually owned and operated a Hurricane.


    MHZ,..... I don't know if he is still around, but, K9AXN may be able to help you with parts / ect.

    I didn't want to spend that kind of money for a delAy tube, wired in a timer circuit and done. I have fun with my sr, has been pretty reliable and quiet a receiver.
