Re: lelon crapcaps in rockford fosgate amp
What is the series of the Lelon 4700uF 50V units?
If not marked, what is the diameter and height of them?
Also, what is the brand and series of the four smaller black and gold capacitors near the large coil?
I may be able to cross-reference them with better quality replacements.My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics. -
Re: lelon crapcaps in rockford fosgate amp
already replaced with elna audio grade caps i had on hand.
the input caps got 1800@16 mcz
no more hissing and whining.
the inputs were open causing alternator whine.
the psu filters were reading 4 ohms esr each.might as well have been open.Comment

Hey my dad has a 20011 Mitsubishi Outlander that uses a Rockford Fosgate audio system. The system still plays music as well as the cd player works, however the display screen is black. Is it possible that a fuse has blown? Any information would be great01-07-2018, 07:59 PM -

How good are lelon caps ? I see some people install RGA Lelons currently. Also could see some old posts where lelons are reffered as the badcaps. -

Disclaimer: This is the first time I step into the realm of analog electronics and my natural language is not English, so please forgive me if I failed to use the correct terms when describing things.
Recently I purchased a Tektronix TDS1012, a 20 years old product for cheap and I thought it could be a nice opportunity for playing (i.e. recapping) and learn something in the process.
The power supply board is exactly the same from this post so I'll just steal it for now.
I'm trying to find replacements for all those Lelon electrolytic caps, but then quickly...
