| PCB ANDA PA PP550 V01 |
Amplifier ini tingkat input mengunakan konfigurasi LTP, bagian VAS mengunakan Hawksford cascode, bagian output mengunakan TEF (Triple Emitter Folower)
Hasil Simkulasi :
PM 75 GM 15
268W/8Ohm, 1kHz -> 0.000755%
268W/8Ohm, 20kHz -> 0.005444%
SR 75
PSRR 1kHz -> 112
Hasil simulasi ini lebih baik dari yang versi free, dimana THD lebih kecil dan SR lebih tinggi. Secara subyektif juga terdengar lebih detail dan lebih bersih, hi sudah lebih soft.Untuk pembelian ada di sini atau di sini

Catatan :
> C39 (20pF) dipasang seri dengan C8 (diganti jadi 20pF), jika hanya C8 (10pF) yang dipasang C39 dijumper.
> C40 (30pF) dipasang seri dengan C5 (diganti jadi 30pF), jika hanya C5 (15pF) yang dipasang C40 dijumper.
> Q7 (MJE340) sebagai bias servo ditempelkan ke pendingin utama atau ke salah satu Tr final.
> Setting bias maksimal 30mA, disetting ulang saat transsitor udah panas.
