Luxman Integrated Amplifier L550 ("L-550") Capacitor Replacement in the Power Supply

[tiefbassuebertr]

The genuine capacitors are ELNA, "Special Made for Audio". The value are 30000 uF (30.000uF) and 50V.
Now my Problem:
The sizes (ratio between height to diameter) is unusual: 63-65mm diameter, 80mm height (industry standart is 100 mm height by a diameter of 63 until 65 mm).

There are no additional space to use larger types - have a look to the second image of opened amp device about
http://audio-database.com/LUXMANALPI...p/l-550-e.html

Are there any vintage caps with screw terminal from Sprague, Mallory, Rifa or Nippon Chemicon in the size 63x80mm ?
Capacity isn't important (at least 10.000 uF) but the ESR must be as low as possible. The rated voltage shold be 63V or 100V.
Thank you for advices.

Thank you. Interesting offer in generall, unfortunately not in this matter. I repeat the wanted sizes:
63-65mm diameter, 80mm height
100mm height like that one from your URL (by the same diameter) is very easy to find.
Perhaps I must ceate a new cover for the L550 with circle cutouts, so that protrudes a small portion of the capacitor height.

how about 35mm X80H - ECE-T1KA103EA Panasonic Electronic Components Aluminum Electrolytic Capacitors - Snap In

Or .. 40mm X 80mm
ECE-T1KA153FA Panasonic Electronic Components Aluminum Electrolytic Capacitors - Snap In

all 4- pin 22mm lead spacing.
check mouser lots of 50v - but out of stock on many >20,000uf.

How strange. I am looking for the exact same thing, for the same amp. I am thinking about this: 22,000uF

Elektrolytkondensatoren mit Schraubausführungen, GT2W227M35060SB, GT2W477M35100SB, GT2W108M51100SB, GT2W228M64120SB, GL2W228M64110SB, GF2H228M64110SB, GT2W338M76120SB, GL2W338M76110SB, GF2H338M76140SB, GT1J478M35060SB, GT2A478M35060SB, GT2W478M76160

35 or 40 mm diameter instead 65 mm ???
Have a look to the ESR values and compare to that one at bottom mentioned versions, that I have found by chance.
Additional question: - how I explain and justify this smaller cap versions with higher ESR values to the owner of this amp ?

65x80mm outline I have found by chance about
Krummer-Kondensatoren
with follow order codes:
800HCA100223Q065080F
801LLA063333Q065080F
801LLA100183Q065080F
and about
Electrolytic capacitor with screw terminals - FTCap Fischer & Tausche Capacitors Group
(FTcap G/GM/GMX Series) follow order codes:
39306365080
22308065080
18310065080
47306365080
39308065080
18310065080
The ESR in general is better by FTcap.

I ask both companies about suppliers for small quantities like Bürklin or mouser and wait to the replies.

If the ESR is low enough, 10.000uF is enough, too. I want to use 100V. Here I get 18.000 uF.

I found a perfect one! This is what I'll personally get:

Mundorf MLytic 22000uF 63V :: M-Lytic Series :: Mundorf :: Electrolytics :: Capacitors :: Passive Components :: Electronic Parts :: Banzai Music

[Tekko]

Alittle low temp spec, 100+ deg C would be to prefer in a amp where stuff close by gets hot.

[Coconuts 500]

The original caps are 85C, and they've lasted for 30 years.

Besides, it will not be easy to find a 22,000uF 105C cap. Especially not one that is 80 mm tall.

Only from the electrical view a good choice (except the temperature range -I would like to use at least 105 degrees) but not from the mechanical view.

Yes - but one device from EPCOS meets both requirements - temperature and sizes. only capacity value is lower: 15mF and 10mF instead 33mF. Here my small overview:
