Re: HP 3403C True RMS Voltmeter display fault


 

Hey everyone,
?
Having recently picked up an Hakko 474 I've decided to desolder every electrolytics in the PSU to test them before ordering some.
To my surprise they're all well within specs, close to new. I now understand why Sprague is regarded as such a good brand, I'm leaving them in. I'm only replacing the blown tantalum on the A7 board.
?
I'll post another update when some DC calibration will happen.
?
Arnaud.
