Iya mas Karso, sayang berat banget trafonya...pcb masih ada tapi yang apex...kalau yang mono sudah ada komponennya...

Cita-cita ingin merakit TDA 7294 racikan MOMOD Ady, tapi niatnya di pendem dulu sambil nabung lagi. Dananya terpakai yg lain, kuda besi minta THR jd harus di bawa ke bengkel. hiks...hiks...hiks. Sorry Mod Ady..pesananya belum di realisasikan.

maaf mau menambahkan pertanyaan.
1. bagaimana meningkatkan power nya?
2. bagaimana hasil di bridge? maupun di pararel?

walaaaahh, jadi HT
lama gak mampir nih

Bootstrap cap: smaller = supports tiny woofer, larger = normal bass
NFB cap: smaller = booming/warm sound, far larger = normal low bass
Input cap: smaller = less of the above, larger = more of the above
Predrive power pins: if you want clear sound, pair of 220uF with solo 2uF or just a pair of 330uF can work.
Output buffer power pins: unnecessarily high capacitance works unnecessarily well and probably enjoyable.
Mute does not require added cap; however standby is same as datasheet

Maksudnya apa yaa?
predrive power pin itu pin no brapa?
gimana meng- pair of 220uF with solo 2uF or just pair of 330uF?

pre-drive ==> +/-Vs (Signal)
Output buffer ==> +/- Vs (Power) atau Vp

Pin ke masing-masing Vs dan "Vp" diberi caps terpisah
Lebih jos lagi kalau Supplynya sekalian dipisah

skemanya pls..,

kurang ngerti nih cara pairnya, apa cuman diparalel 220uF atau 330 uF di Vp dan 330uF di Vs (signal)

Saya nangkapnya seperti ini
