This page presents general details of the 1,000 WATT RMS "BROWNOUT" amplifier produced by WOLFF INSANITY AMPLIFICATION, Portland, Oregon, USA.

This amplifier is included on this website because of its novel and innovative design and construction in the 1,000 watt tube musical instrument amplifier category.

The Hammond 1650W dual hi-fi output transformer configuration is of particular interest because of their capability to easily handle the amplifier's rated power across the full audio frequency power response.

Note the innovative design where five pairs of KT88 power tubes are connected through one pair of transformers to match the loudspeaker load impedance (in each channel).

The pictures and information included here are extracted from various websites and are all I can find. Copyright in the pictures and amplifer design is with the owner Wolff Amplification.

SPECIFICATIONS:

POWER OUTPUT = 500 W rms per channel

FREQUENCY RESPONSE = 15Hz - 23 kHz + - 3 db

POWER TUBES = 20 x KT88

B+ supply = 650 VDC @ 0.6 A DC zero signal idle current (30 mA per KT88)

B+ supply = 580 VDC @ 2.5A DC maximum signal full power

MAINS POWER = 17A @ 120 VAC at 1,000 watts rms audio output

Note: Australian Standards limit the power rating of a domestic power point to 10A at 240 VAC. This amplifier is within that limit
