Re: FIC VA-503+ best replacement for Vcore caps



One note: All but one of the small electrolytic capacitors are 10uF/25V. One of them is 22uF/16V.

I replaced all the large capacitors on my VA-503+ board and it still would not POST. After replacing all the 10uF & the single 22uF capacitor, it comes right up. Success!...

This is great information. Thank you. I'm going to try as you suggest....

Hi all,

I stumbled onto this thread and am dealing with a VA-503+ recap, myself. I went onto mouser.com / digikey.com to find suitable caps and realized I needed the ESR. To that end, I recently discovered / bought an [URL="https://www.amazon.com/Mega328-Digital-Transistor-Resistance-Capacitance/dp/B07WT9VVZB/ref=sr_1_3?dchild=1&keywords=LCR-T4+Mega328&qid=1610752969&sr=8-3"]LCR-T4 Mega328[/URL] which seems to do reasonably well with ESR measurements.

Long story short, I popped off...

Thanks to everyone who's contributed to this site. It's a great source of info.
