00:00If you've ever finished an amp build and thought, something's just, missing, I bet money it's not your tubes or
00:05your transformer, it's the capacitors sitting in the signal path.
00:09So I went digging and pulled together 5 MKP audio caps that DIY builders keep coming back to, all of
00:14them with thousands of orders and ratings that barely dip below 5 stars.
00:18And honestly, the prices on a couple of these genuinely surprised me.
00:23Let's get into it.
00:25First up is the 10G MKP series, metalized polypropylene, with a silver-copper line construction and a tight plus or
00:32minus 3% tolerance.
00:34That tolerance number is the part one care about, because in a crossover or a coupling position, sloppy tolerances mean
00:40your left and right channels don't match, and your stereo image smears.
00:44You get two of them for $9.45, which is the priciest pick here, but you're paying for consistency.
00:51Nearly 5,000 sold and a 4.9 rating tells me people aren't sending these back.
00:56If you're building something you actually planned to keep for a decade, start here.
01:01Next, the 250V MKP audio caps, sold as a 2-pack.
01:06What I like about this one is the sheer range of values, 1, 1.5, 1.8, 2.2, 2
01:12.7, and 3.3 microfarads, so you can dial in a crossover point without compromising or paralleling three caps together
01:19to fake a value.
01:21$3.11 for a matched pair is almost silly.
01:25Metal film construction, non-polar, great for coupling duty or frequency dividing in a speaker build.
01:31Also 4.9 stars across about 4,600 orders.
01:36This is the one I'd buy just to have a drawer full.
01:39Then there's the 5-piece Axial MKP set, and this is where things get fun for tinkerers.
01:45The value range on these goes all the way from 1 microfarad up to 47, which covers basically anything you'd
01:51throw at a crossover network.
01:535 pieces for $2.52, do that math, it's about 50 cents a cap.
01:59Rating sits at 4.7, slightly lower than the others, but at this price it's the perfect set for prototyping,
02:05breadboarding, or swapping values until your ears tell you you've landed.
02:09Buy a few sets, experiment freely, and don't feel bad about it.
02:14Fourth is the AudioFiler MKP, and this one earns its spot on voltage rating alone, you can get it in
02:19400V and 630V versions.
02:23That matters a lot if you're building tube amps, or plate voltages will eat a 250V cap for breakfast.
02:29Values run 1.5 up to 4.7 microfarads, electrode-less metal film, $4.10 for a single piece.
02:37It's the safe, sensible choice for high-voltage coupling positions, and with a 4.9 rating and 4600 sold, plenty
02:44of tube guys clearly agree.
02:46And the last one might be the best value on this entire list, the AudioFiler Axial MKP, single-piece, $0
02:52.82.
02:54Under a dollar.
02:56It comes in 250, 400, and 630V versions and covers 1 microfarad up to 10, so you can mix and
03:02match exactly what your build needs instead of buying packs you'll never use.
03:06It's also the only cap here sitting at a perfect 5-star rating with over 4,500 sold.
03:13Axial leads make it easy to mount neatly in a crossover too.
03:17Honestly, just grab a handful.
