Well, I need a big-capacitance high-quality capacitor to drive my headphone amplifier (we are talking 200-500uF capacitance and at least 400VDC working voltage). I don’t have too many choices (or perhaps no choice at all!). So I would go with this Unlytic Film Capacitor.

Yes I could go with Electrolytic capacitor but the sound would be not at my expected level.

So I welcome “The Giant” Unlytic capacitor :) Want to know how big is it? Keep reading.

First comparison, I use standard AA battery. How tiny are you? I mean the AA battery. The Unlytic itself measured around 75mm (diameter) and 155mm (height).

Another comparison with my RCA 5U4 Rectifier Tube and 2 smaller tube (I forgot the number). And off course with a standard AA battery ;)

Two twin towers for my next headphone amplifier project. Based on my calculation, with 290uF and 32 Ohm of my Grado, I could get the low down to 17 Hz. Hmm… not bad I think. For normal 50KOhm load, I could go as low as 0.0109817702613661 Hz!

I wonder how to put it on my chassis… Oh well, we will think it later… :)

    pak jimmy, sy punya elco nganggur BHC aerovox industrial als30 4700uf 450 vdc apakah bisa dimanfaatin buat tube preamp? terima kasih.

    Hi,
    Bisa banget donk. Asal pakenya di bawah 450V ya (dan hati2, pastikan dulu elco tidak bocor).
    Selalu gunakan bleeder resistor dan jangan menyentuh caps saat nyala atau langsung setelah OFF (harus nunggu tegangan turun dulu, silakan cek pake Multimeter).
    Utamakan safety selalu. Tegangan di atas 300V lumayan buat bikin kaget hehehe.
    Thanks.

    tq pak jimmy atas infonya, saya sempat meragukannya karena nilai 4700uf tidak pernah saya jumpai di skema tube power supply.

    Hi,
    Memang sebenarnya terlalu besar Pak…
    Thanks.
