I have a 2007-era Panasonic VHS combo that is full of of Elna RJG capacitors. I am trying to test the capacitors to diagnose the machine and then select replacement capacitors but I can not find any datasheets for them. I did find a Elna catalogue from 2007-2008 but there is no mention of this capacitor series. Where these specially made for Panasonic and so not made available to the public? Any ideas what to find out what the ESR values should be without the datasheets? They are all between 10V and 50V and 47uF and 1800uF. None are leaking or bulged but I know that they need to be tested to be... -
Hi,
I'd like to recap some of my old mainboards (they are from 1998) before switching them on again for the first time after many years in storage. All caps still look good from the outside.
There are three mainboards:
- ASUS P5A rev 1.04
- ASUS P2B-S rev 1.03 "Rubycon"
- ASUS P2B-S rev 1.03 "Chemi-Con"
If you are interested in their specs, The Retro Web has pages for the P5A and the P2B-S.
They all have many 1000uF 6.3V 105°C capacitors. But there are some differences I cannot figure out.

I've got a Toei arcade CRT chassis and printed on the PCB is CM-R14 but it might be a CM-R20 and so far needs two caps replaced, I've looked on the Nippon Chemi-Con site and got their 2020 catalogue I cant find any info about the first cap in the catalogue or on their obsolete catalogue, on the cap is:
(Radial electrolytic cap) Nippon Chemi-Con 1uF 160v 85c 8mm diameter, roughly 15mm long (cap is bulging at the legs) with 6mm PCB hole spacing, the chassis service manual says this cap C58 is a CE04W with "04" in a smaller font than the capital "CEW" so it must be... -
Hello,
I need datasheets for EN7521 and MT7520 (similiar chips). This is GPON ONT.01-17-2025, 01:47 PM -
I'm desperate to save my pair of 2007 KRK VXT6 studio monitors, one of which died.
Hoping for an easy fix, I bought a pair of new-old-stock replacement main boards. I installed one & it was DOA. Tried the other, also DOA. I suspect that 15 years in a Maltese warehouse dried out the electrolytic caps. I tried replacing just the two largest caps, which didn't help. Except to confirm that the old ones wouldn't reach infinite resistance & were a gram underweight.
Q: How do I match the caps, since there's no series marked on the originals and no circa-2007 catalog or datasheets...
