$$$$$$$$$$$$$ SALE PENDING $$$$$$$$$$$$$$$ Selling a Pair of VAC PA160 mk.1 monoblock amps for my brother. He is the original owner and told me he has taken great care of these. I believe they are about 20 years old. I do not have the original boxes or manual but I will make sure they are packaged very very well for safe shipping. One of the amps is missing the power knob. Each amplifier without packing weighs 52 lbs and with packing weighs 63 lbs. All times two. Each box is 25x16x13 inches.

The lack of emphasis on measurements is due to the fact that engineering's arsenal of equipment and techniques do not operate on the pattern recognition principals that control human perception of sound. In the immortal words of Daniel von Recklinghausen, if it measures good and sounds bad it is bad. If it measures bad and sounds good you've measured the wrong things. The following describes typical measured performance of a PA160 operated at 120 VAC, 60 Hz. Power Output: Continuous average power at 1 kHz depends upon the tube type fitted and the operating mode selected. The following table summarizes a few popular combinations. The entries show power, and load impedance connected to the 4-8 ohm tap. In each case THD is less than 2% with feedback setting of "A" for triode, "D" for ultra-linear, "E" for pentode. Mode KT88 KT77 EL34 6L6GC Pentode 160/4 125/4 150/4 100/4 Ultra-Linear 152/4 120/4 118/4 70/8 Triode 79/4 60/4 58/4 30/5.5 Frequency Response: down 0.5 dB at 5 Hz and 48 kHz, ref 0 dB = 1 watt @ 1 kHz. down 3.0 dB at 3 Hz and 82 kHz, ref 0 dB = 1 watt @ 1 kHz. Power Bandwidth: down 0.5 dB at 12 Hz and 42 kHz, ref 0 dB = 150 watts @ 1 kHz. down 3.0 dB at 8.5 Hz and 75 kHz, ref 0 dB = 150 watts @ 1 kHz. Ultra-linear mode, KT88 tubes. Distortion: Typically .23% THD at 1 kHz 10 watts, 88 dB Negative Feedback: Variable. Table shows amount for triode/ultra-linear/pentode modes.
