While contemplating spending far too much money on a bypass capacitor, I ran into this lovely thread on a Vietnamese version of DIY Audio. I'm particularly aroused by the naked Duelund's in the back of the car.

Has anyone ever tried to buy their own copper foil roll sheets and make their own PIO caps? Seems simple enough with an LCR meter to get what you need. Would look cool too.
Somehow every country we fight in war ends up doing really well afterwards. Look at Hiroshima today. Maybe somebody should nuke Detroit.
What a completely inappropriate point to make here.
I bring up a DIY forum in a foreign country and some one brings up the desire for violence and justification for past wars with them. I'm aghast, really. How can anyone be motivated to go from interest in foreign countries for cool electronics to making blanket statements about war and violence truly shocks me.
Best,
Erik

Yes, but the performance would almost certainly be poor, although poor performance and a high price is a near guarantee that a small segment will worship the results.
That will be no worse. 😀 Home-building caps is a daunting task unless you don't care about quality.
Making a secure connection to aluminum is not trivial unless you have a zinc sprayer.

It's very non-fancy but I found poly film-in-oil industrial electric motor caps to sound quite nice. They are about $12 for a 50uF and 450v. Big aluminum can with sloshing oil inside. But I am no cap connoisseur so have no idea what a $4000 Duelund can possibly sound like? Voice of the virgin goddesses of Mt Olympia (Duelund) vs table radio (indsstrial cap)?
Is ASC a brand of motor cap? Here is what I used:
Motor Run Capacitor RC0015 - 50 mfd 370 V VAC Volt 50 uf Round HVAC TEMCo AC Electric
ASC makes all kinds of caps, but they do offer a motor-run line. Here's Allied's page for them:
Capacitors - Passive Components from Allied Electronics
ASC cost a touch more, AFAICT. FWIW, I use the enameled wire from TEMco to wind my coils.

For anyone in Europe try searching for 'Shizuki' capacitors on eBay. There always seems to be lots of new WME-RS series caps for sale at very reasonable prices. From what I understand these are essentially the same as the ASC caps (ASC = American Shizuki Co). I bought 4x 40uF Shizuki WME-RS caps last week and they measure 40.36uF, 40.59uF, 40.70uF and 41.06uF. I bought a batch of 8uF ones a while ago and they were similarly close in capacitance. Performance wise, I haven't found better for tube PSUs or high value coupling caps. Not tried Duelund though, but not losing sleep over that (I'll be a lucky man if my system ever evolves to the level that the best use of $4K is a single cap).
