Power supply capacitors

[Willy6]

Does anyone use the LKG series Nichicon capacitors for the big main power supply caps?

Yes for some apps. I used KG's. For my MX-2000 I used these " Super Through's"

I was looking at some 22000uf 100v LKGs to replace the 12000uf 100v caps in my G-9700 they measure out the same as the originals 50mm dia x 100 mm length

My mistake they are 15000uf 100v LKG caps

Pretty big jump in capacitance.. Inrush surge will be harder on the power switch and rectifier diodes.

15,000uf is a little more tolerable than 22,000..

Yes it is the 15000uf 100v caps that are the same dimensions as the originals

Based on my discussions with a marketing guy at Nichicon those 15k caps might well come in at 13.5k, down 10% from design but well within the ±20%. Meeting the sales specification and saving Nichicon a ton of money in materials as they make the caps closer to the lower limit. This building to below rating but well within spec is for the big caps.

That to me makes the 15k cap a great choice to replace the 12s.

I've used Super Throughs for main filter caps and Fine Gold's for coupling caps in a few cap coupled amps before. I used the Super Throughs in one of the two Marantz 140 power amps I have also. Even for the price you pay for them, they are still cheaper than many if the other "audio grade" caps I've seen, or used.
