POWER AMPLIFIER
STABLE AT 2 OHMS!
MADE IN THE USA!

for sale

I worked for a Peavey dealer for many years and have toured about 25 of their plants in MS and I consider this series to be the best, overall power amp they did. I have installed many in clubs, churches and touring rigs with total confidence. I knew when I installed one, it was going to stay "gone" and keep working strong.  
Features:

- Super fast Slew Rate for bass transients
- Big damping factor for tight bass

- Stable down to 2 Ohms!
- Big Power, rated as follows;
8 ohms = 250 wpc
4 ohms = 500 wpc
2 ohms = 750 wpc

- Speaker outputs via 3-Way binding / banana posts and 1/4", "all metal" phono jacks
- Built-in and defeat-able DDT
compression
- I/O's for Peaveys' X-over "cans" if you desire. (a great and potentially money saving feature if using the amp in a "multi-way" speaker set-up for for filtering out unwanted frequencies.

- Stereo / Bridge-Mono selector (Potentially turning the amp into a single 1000 watt monster
- Real Power Supply (sorry but real power requires "real weight" and huge transformers and caps)
- "REAL" TO-3, Metal cased output transistors
- Grounded AC input cord


Unit works gr
eat. We have completely gone through the unit cleaning and testing all.
SPECS:

- Slew Rate 40 volts per usec in Stereo mode. 80 v/usec in Mono mode

 This unit has had complete service including cleaning everything including all switches, controls and contacts. Only issue is the the power switch would not turn "off", nor was one available, so it was "shunted-ON" so to the unit will need to be powered off with a switched AC outlet or similar. Other than that refurbishment came out fine. All inputs tested and both side produces clean and even sine waves into static 8 & 4 ohm loads! No power supply hum of any kind. It's dead silent!

Here's a great way to enjoy a modern A/V, cinematic amplifier with the ability to also connect a turntable (most modern A/V units have omitted a Phono input). The Yamaha DSP-A2070, 5-Channel, 350** watt A/V integrated amplifier. From Yamaha literature,
"The DSP-A2070 breaks new ground. The A2070  provides the most versatile control and switching yet on a Yamaha product. It's also the first Yamaha component to provide digitally processed Dolby Pro Logic and Cinema DSP with Pro Logic Enhanced and 70mm Theater settings".
Probably the best thing about the Yamaha DSP-Axxx units from this era are that they are utilizing Class A/B amp designs instead of the newer, lightweight, cheap Class "D" designs coming out of most of the Chinese products you see currently on the market for less than $1000. That is why the older gear generally sounds vastly better than the new gear for regular, old 2 channel audio listening. The new stuff is fine for watching movies and TV, but typically horrid sounding for listening to CD's, Vinyl or quality tapes.
Comes with it's original "learning" Infrared *remote control.
Features include:

- Dolby Surround Pro Logic Decoder
- 5-Channel "Surround Sound"
- Motorized Volume control (operates via original Infrared Remote Control)

- Large illuminated LCD display with various mode functions.

Controls:

- Motorized Volume control (operates via original Infrared Remote Control)
- Motorized Input Selector (operates via original Infrared Remote Control)

- Bass Extension Boost selector
- Bass (analog Pot control)

On our test bench, both internal front channel power amps produced 29 volts per channel at 8 ohms for 128 watts per channel and 29 volts at 4 ohms for 210 watts per channel via discrete, epoxy output devices (2x 2SA1302 & 2X 2SC3281).

We have completely gone through this unit, cleaning inside and out including all contacts, switches and controls. All indicator lamps checked. All functions tested for perfect operation. All inputs tested and both side produces clean and even sine waves from all amplifiers! No power supply hum of any kind. It's dead silent! Following restoration procedures, the unit was ran continuously at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 48 hours. Only cosmetic issue is some tape residue on the top sheet metal panel, that did not want to be removed. The unit looks, sounds and works beautifully.

Here's a great way to enjoy a modern A/V, cinematic amplifier with the ability to also connect a turntable (most modern A/V units have omitted a Phono input). The Yamaha DSP-A1000, 5-Channel, 350** watt A/V integrated amplifier. From Yamaha literature,
"The DSP-A1000 breaks new ground. The A1000 provides the most versatile control and switching yet on a Yamaha product. It's also the first Yamaha component to provide digitally processed Dolby Pro Logic and Cinema DSP with Pro Logic Enhanced and 70mm Theater settings".
Probably the best thing about the Yamaha DSP-Axxx units from this era are that they are utilizing Class A/B amp designs instead of the newer, lightweight, cheap Class "D" designs coming out of most of the Chinese products you see currently on the market for less than $1000. That is why the older gear generally sounds vastly better than the new gear for regular, old 2 channel audio listening. The new stuff is fine for watching movies and TV, but typically horrid sounding for listening to CD's, Vinyl or quality tapes.
