Tube Stereo Amplifier 2xEL34 PP / 35Wrms ReDesign PCB (Elektor) All In One PCB

Power Tube Amp, with 2xEL34 PushPull in final stage. Input stage are pentode EF86. Include

Power Supply (negative, and HV), and adj timer. Project from Elector, PCB from me.

The output power is around 35Wrms per channel. The schematic is shown in PDF file from

Elektor magazine. The PCB have easily breaking with a "guide" (to be a separate pcb, audio

channel, power supply, etc).

Input impedance : 1 MΩ

Input sensitivity : 600 mV

Impedance : 8 Ω (4 Ω optional)

Maximum Power : 39 W into 8 Ω

Bandwidth at 1 W : 5 Hz – >40 kHz THD+ noise (1 W/8 Ω, 1 kHz): 0.06% (B = 80 kHz)

Signal to noise : 62 dB (B = 22 kHz) 88 dB (A-weighted)

Supply voltage : Rail voltage - AC 320V / >400DC 300mA

Filament voltage : AC 6,3V > 7A

Board Dimension : 254mm x 174mm.

No components !!!.
