Have some 3,3uF/100v. I will connect three in parallel to 9,9uF, and that almost 10uF?
The B1 must be the best "preamp" I have used in my different stereo systems during the last 40 years. I have built a lot of tube preamps, and have owned Preamps from Tandberg, Electrocompaniet, Audiolab, Denon(expensive ones), and a lot of other, cheap and expensive ones, but the B1 sounds fantastic.Clear, open sound. Now I am using a Gainclone with LM1875 as a poweramp. My ACA is also a fantastic combo. An class D Hypex who costs 15 times compared to ACA and the Gainclone is stored away. Nelson Pass, Thank You!
I have used the MKT1813 as an output - coupling - cap in a few of my amps
with very good results.
I used the MKT 1813 in the frontend of my BA-1 poweramp. Also in one of my preamps.
I think caps have an effect on the sound but not as much as the active devices.
But the cap - discussion is endless.....
Use them. It is not a big deal to desolder a cap and try another one.
You can also use super expensive alu - gold - silver - in paper - in oil - in wax - super big - mega - caps. Some sleep / listen better...
I have used some "cheap" Chinese polyprop in my first B1, but it sounds great! I think a good curciut are not so dependent on the "quality" of the capacitor? During the years I have picked capacitors and resistors from "old" industrial equipment, and used them in my projects, and with good results.
The ERO MKT1813 is a great capacitor! I finally finished my B1 buffer and the sound is better than my second B1. I have to recommend the ERO MKT 1813 as an output capacitor for the B1 buffer. My second B1 has a 10uF polyprop output capacitor, but my new B1 sound much better, and the only differance between these two B1 buffers are the output capacitors. I think I have to dig up some ERO MKT1813 for the other B1!
