hafler amplifier. Hafler DH-200 is a 100 watts-per-channel MOSFET class AB stereo power amplifier. MOSFETs are solid-state devices that work on principals more similar to vacuum tubes than bipolar transistors — and it sounds great! This amp was upgraded in 2021 35 years ago when the DH-200 was introduced, it astounded the world in having performance so high that it exceeded the abilities of most laboratory equipment of its day. It was also reasonably priced, making this Hafler amplifier astounding both for its incredible performance and unheard of price. This amplifier is from the very pinnacle of home High Fidelity. Products got better and better ever since home amplifiers were invented in the 1920s, but video took over home entertainment by the late 1980s, and home Hi-Fi equipment never evolved past this stage. Newer Hafler amplifiers, and the home audio market in general, has been neglected for lack of interest ever since the VCR became affordable to everyone in the late 1980s. There are newer amplifiers, but few are better than this Hafler DH-200. David Hafler was one of the founders of Dynaco in 1954, and started the Hafler company in 1977. It's a traditional class AB linear power amplifier in a sheet metal steel case. It has a traditional unregulated linear power supply with a big power transformer in the middle of the case, a bridge rectifier and two 10,000 µF 75V capacitors on which I measure ±55 VDC. The loose regulation of the power supply gives it much greater burst power than continuous (perfect for music), and also means that power output doesn't completely double as speaker impedance halves. It has eight power MOSFETs (4 per channel) in TO-3 packages mounted to two big anodized aluminum heat sinks on opposite sides of the case. There's a neon pilot light in the power switch as well as a yellow overtemperatgure light on the front. The DH-200 has one 5 ampere 3AG slow-blow power-input fuse, and 5A 3AG fast-blow fuses on the B+ and B- rails of each of the two power amp modules. It has speaker fuses to protect your speakers from you doing something stupid. Most amplifiers don't have speaker fuses. Unique to the DH-200, the speaker fuses are inside the feedback loop to maintain high damping factor and null any sonic degradation form the fuses Audio Input One stereo pair of 1/4 RCA jacks with individual potentiometers. 22 k?. 1.5 V RMS input for 100 watts into 8?. Audio Output Connectors Standard 5-way binding posts on standard 3/4 centers. Total four pairs or 8 posts. Size 5-1/8 x 16 x 10-1/2 inches, HWD.
