Very sorry about loosing the last little bit of fix. Life gets in the ways sometimes. the current limited worked fine, there was a problem with the volts display and was a bad resistor in a voltage divider

The problem fixing it that way is that you don't know how close you are from the margin and it can suddenly vary/oscillate again.
Did simply inserting the current op-amp into the circuit fix it? Kinda what I was thinking although it makes no sense to begin with. ;-)
Funny ending🤣 Thanks
Great ending. Ha ha. Glad you got it working.
I hate to be thick, but I did not understand the ending comment. Clue me in, gently, please.
@@t1d100 It's the fact it just ended with a caption. :)
did you read the description
Thank you for the clarification.
In my HP/Agilent manual for the E3610a, R46 is listed as 390 ohms, 5%, 3W. So look for a space suitable for that size on the PCB. It's also described as being a "PWI" resistor - not sure what that means. Good luck!
I think PWI stands for, PowerWise Interface
@@mickblackmore290 You know, I saw that too. But digging further into the parts list, and since some of the power resistors are described as "PWN", it looks more like PWI = Power, Wirewound, Inductive. Vs PWN= Power, Wirewound, Non-inductive. Maybe!
@@craighosty1353 Then I'm thinking That that ( I ) started out as an (N ) and lost something in the printing. Makes way more sense
@@mickblackmore290 Mouser sells wirewound inductive and non-inductive power resistors (special winding technique). I'll go with "Power, Wirewound, Inductive" as HP/Agilent's meaning for PWI in their parts list.
@@craighosty1353 That works to. I always thought wirewounds were always inductive unless specified otherwise. I also think if they are going to use acronyms they need to define them where used. JMO
Sorry sir, how do you get that schematics diagram?
How fixed the current regualtion?
replaced op-amp
