Top Class Warm High Fidelity Sound
Assembled NEC PCB Board Made in Japan 1970s
NEC 7A Complementary Pairs 2SA627 PNP and 2SD188 NPN TO3 Power Transistors on Heatsink
Closed Loop Gain: 28dB, 25X, (68kOhm / 2.7kOhm)
Input Impedance: 68 kOhm (Industry Standard)
Size: 20cm x 7cm x 7.5cm (8in x 2 3/4in x 3in)
70V Reel-to-Reel Sinus delivered to your speakers
A Soft Start Circuit, to limit the inrush current on turning ON
The symmetry that balances your amplifier with the lowest possible DC offset, an immeasurable mean amplitude displacement from zero
All critical currents are regulated for a wide power supply range from 2x14V to 2x43V
Requires a symmetrical power supply, 2x36.5V 2x3A 219VA 73V CT with 2x6800uF recommended
Matching power symmetrical 2x36.5V 2x3A 219VA 73V 3A CT 219VA transformer 120V 60Hz I am selling for additional $80
Minimum power supply: symmetrical 2x14V
Maximum power supply: symmetrical 2x43V
