Re: Challenging 2465 PS repair

I am completely ignorant about this instrument; but I think you might consider putting the resistors in series. In a 2465B/2467B service manual I found on the web, I found in the circuit description (page 3a-52) "+5 V Regulator" that current limiting is set to limit current to 2 A. 4 ohms would load the supply to 1.25A and 1 ohm would load it to 5 A - well above the current limit.
