The Stax SRM-001 mod thread
Mar 26, 2018 at 4:48 PM Post #407 of 440
Hi
Frankly, I don't remember how did the original baby stax sound ( I bought them from Japan in 2012), but, after modding, they sound very, very detailed with good bass. I compare them to my Massdrop Hifiman 4EXX with JDL Labs amplifier.

Can we put a 14500 battery with AA together. In order to increase volts. Like 3.7 + 1.2= 4.9 about?
Hi
till five months ago I used these batteries (see the attached photo), but, at the moment I use the Baku BK-1502D+ power supply with great satisfaction.
Best Regards

Hello. I have here is there is stax srs-002 (mk.2) and I'm wondering, is it possible to push battery brand 18650 3.7 v each? Anything happen to the amplifier?

It seems that the original Sanyo 350v 2.2µF caps in my unit are starting to dry out, so i'm looking to replace them with something that will actually fit inside the original unit.

it is my understanding that I shouldn't change the µF, but could go with higher voltage?

what are the better brands still in production?

I might also replace the other caps on the board as well (see pic) should i keep the same ratings, or change anything?

As all proposed output capacitors are very hard to find, here is what i have found from Farnel.
The soundstage is very nice and open. At first the sound was too warm for my taste, but after 30-40 hours of burn in it settled down.
Here is the part number: MKP1839310631

film instead of electrolytic, and at 0.01µF instead of 2.2µF?

This is for the output caps C7 and C8 and this is the right value.

Did you actually read my original post? I asked for replacement for the electrolytic capacitors (which i marked in my photo) because at least one of them has dried out, and then you're recommending i replace another capacitor that, as far as i know, has no issues at all.

The main concern for me is C13, as this shows lower capacitance than C14, C15, and C16

But i'd rather replace those 4 at once, and since it seems that at least one cap has starting to fail, i'd rather try replace all electrolytic caps at once.
