Nelson Pass : "I wanted an amplifier easy enough to lure unsuspecting audiophiles away from blind consumerism and down the slippery slopes of DIY obsession..."

maksudnya current source itu apa ya ? itu bukan cuma sebagai tahanan doang kah ? kok kalo di skemanya gambar lampu pijarnya kodenya R2 ?

kalo B1 Salas ini LEDna diganti lampu pijar gmana ya ? mungkin yang buat batere aja sih. hihihihi.

current source : sumber arus.
lampu pijarnya pada tegangan tertentu akan menghasilkan tahanan tertentu (R2),
P = V^2/R
kemudian tahanan ini digunakan sebagai pembatas / sumber arus.
I = V/R

kayaknya ga bisa deh.
kelihatannya bisa tapi perlu experimen untuk mendapatkan tegangan yang tepat dan mungkin noisenya bakal naik.

Salam kenal semua... Saya sangat tertarik dengan forum ini. Apalagi pembahasannya sangat menarik. Kalau menurut saya, De-lite PA menggunakan lampu pijar sebagai pengganti R. Dimana R turut menerima beban sangat besar dari T sehingga untuk mengehemat biaya (heatsink dan penggunaan R dengan W yang besar) digunakanlah lampu pijar sebaggai penggantinya.
