Photos 1 & 3: 270uF 35V Capacitors. Photo #2: 390uF 25V capacitors. Odd values for capacitors.

They're Panasonic, since you didn't bother telling the diameter I can't say the exact series but at least FK,FC,FR have those values. Could be fake ones too.

They look like FR series.

Not odd at all. 220-270-330-390-470 all normal steppings.

You obviously have not been into vintage electronics for the last 40+ years of your life.

Or even lived forty+ years?

I feel like i'm being shamed right now...
I do read datasheets.
I've taken apart many electronics new and old and never came across those two values but i have seen other "less common" ones like 150µf, 560µf and 68µf.
The reason why i've have not seen them in datasheets is because if i'm looking for a certain size i end up skipping over all of the others until i find the one i'm looking for.

I feel like i should just leave.

Shame is good, builds character!

When you can bend over in the middle of Wal-mart and puke your guts out and not feel shame, you've got enough character. Not until.

As a car audio fnatic who does massive builds (6000W RMS, dual 15's in a coupe, etc.) I can tell you that Alpine is one of the best brands out there, right up there with JL Audio (JL is the best, hands down).

The last Alpine amp I had to open was one that was shaken so hard the pins that went from the PCB to the RCA jacks had broken off and shorted out all of the mosfets on one side, killing the amp completely.

However, the build was always amazing. Dual switching transformers, all caps were either Elna, Nichicon or Panasonic, never seen anything else inside them (except for older ones and some of the newer class D ones that have had NCC in them).

I would be extremely surprised if they were fake, especially considering how costly these amps are.

To put the cost of the amp in perspective, their 1000W class D monoblock is ~400$ depending where you get it. A standard class D amp from a brand like SoundStream (who also makes great stuff) is about 150$, both are certified to make their power AND have been tested to make more or over their rated power.

IMO, they're probably real panasonic caps, which wouldn't be anywhere out of the ordinary.

Also, Alpine makes the stereos in higher end Buick cars, and they make the stereos for Jaguar and a few others.

alpine was the high end option in BMW's - not sure if it still is.
low end option was Blaupunkt!!!!!
