This Hafler DH-200 Power Amplifier is perfect for those who are looking for spare parts or who would like to repair it. This amp is being sold for parts. As seen in the pics, it powers on, the power light turns on. This amp has two fuses on the back panel, one of them is missing as well as the fuse cover. Might be an easy fix, but don’t know for sure…

Hafler DH-200 Amplifier & DH-101 Preamplifier Hafler DH-200 amplifier, from the original owner, in very good cosmetic condition, however it has low output/distortion in left channel, otherwise good. Hafler DH-101 preamplifier, also from the same original owner, in very good cosmetic condition, when testing I only get a loud hum through the speakers, using any amp (I used the aux input---didnt bother trying any others---if it needs attention, it NEEDS attention) so obviously both amp and preamp will need attention---unfortunately just another project I simply dont have the time for right now---my loss/your gain. I believe the condition of these makes them great candidates for restoration. Complete with original manuals, assembly instructions, and schematics. Payment must be received within 24 hours of end of listing. Will ship via FedEx within one day of completed payment, fully insured and VERY WELL packed. Guaranteed to be as described in the listing, and as shown in the photos, but due to the nature of vintage audio gear, no other guarantee or warranty is expressed or implied. Any questions at all, please just ask.

For sale, a restored and upgraded vintage Hafler DH-200 MOSFET class AB audio power amplifier. I restore and upgrade vintage Hafler power amplifiers as a hobby, this is my latest completed project. Restoration includes replacement of all electrolytic capacitors with Nichicon audio grade, and non-electrolytics with polypropylene film or ceramic types and replacing broken or worn parts. Also installation of new insulators and thermal compound on all output transistors. DC offset is checked and if its greater than 10mV then I replace the input stage Darlington pair matched transistors to get the offset to where it should be. Output transistor bias was also set to factory spec of 250mA. Upgrades include replacing input and output jacks with gold plated jacks, larger power supply capacitors and installation of an inrush current limiter. This amplifier is rated for 100 watts per channel into 8 ohms, however I measured almost 145 watts per channel into 8 ohms! Hafler MOSFET amps are known for their smooth sound and this amp sounds great! The case shows wear and tear and isnt pretty, but its whats inside that is really fantastic! This amp is one of the later models with the rounded heatsinks, older models have sharp-edged heatsinks. I do have a rack-mount faceplate for it for an additional $75. Here is the work that has been done to this particular amplifier: Replaced both speaker fuse holders Installed insulated gold RCA jacks with 2.2ohm ground lift resistors on both channels for reduced noise Installed insulated gold binding posts Replaced power switch Replaced power cable Installed new 20,000uF 100V Kemet power supply filter caps, original were 10,000uF 75V All TO-3 MOSFET output transistors repasted with new mica insulators CL-40 Inrush current limiter installed Recapped both PC-6 circuit boards with Nichicon kit from fantasiaaudio on eBay Replaced Darlington pair transistors with matched set on both channels Replaced bias trimmer potentiometers Replaced feedback circuitry resistors with 1% tolerance resistors Left channel DC offset measures 9.1mV after 30 minute warmup (see photo with voltmeter measurement) Right channel DC offset measures 3.2 mV after 30 minute warmup(see photo with voltmeter measurement) Left channel power output measured at 143 watts into 8 ohm dummy load (see photo with oscilloscope measurement) Right channel power output measured at 144 watts into 8 ohm dummy load (see photo with oscilloscope measurement) Buyer pays flat $29.99 shipping!!!

This listing is for a used good condition Hafler DH-200 stereo power amplifier. This item is only tested for power. Due to this fact Ill be selling for parts and repair only, doesnt mean it doesnt work, just tested for power only. Let me give you some background.This was purchased at an estate sale along with tons of other equipment, tonsss. The person who passed clearly must have fixed these as a hobby or a living. I bought near an entire wall of similar equipment which will be listed in coming days. He had a repair room that was 10x15 long. I dont know if the was formerly repaired or not. So far - the equipment I have tested 8/9 have worked good. One didnt power on at all. Im at the point where, its just to much to continue testing. So Im selling As Is. This was connected to a DH-101 in the home. This listing is for the Hafler DH-200 only. Selling As Is In coming days look for tons more being listed all will be sold separately. Dynakit mark IV Hafler DH-101Hafler DH-220Hafler DH-500Quad 303Quad 323JVC S.E.A Equalizersand much more. All sold separately. **If purchasing from out of USA, you must reach out before purchase so I can pack and get an exact weight and measure to ship out.

I am selling this Hafler DH-200 amplifier for parts. I am the original owner, having purchased it as a kit in the mid-1980s. After acquiring it, I brought it to an audiophile stereo store, where a technician assembled it and incorporated a modification that significantly improved its sound quality. Regrettably, I cannot recall the specific type of modification kit used. The amplifier was housed in my smoke-free studio and reliably powered my Yamaha NS-10Ms for many years, delivering excellent 100 watts per channel performance. However, a couple of years ago, after moving, it ceased functioning correctly. I consulted a hi-fi repair specialist who diagnosed the issue as stemming from a few faulty capacitors, resulting in the left channel audio breaking up. The repair cost quoted was exorbitant, hence my decision to sell the amplifier as is for parts. The sale is final. Rest assured, I will package it securely. If you have any questions, please feel free to ask.

Das Gerät ist optisch in gutem Zustand. Das Gehäuse hat ein paar Kratzer, vor allem auf der Oberseite (siehe Bild 4); die Frontplatte ist in gutem Zustand. Bei einem der beiden Sicherungshalter ist am Rand ein wenig abgebrochen, er lässt sich aber einwandfrei verriegeln (siehe Bilder 6 & 7). Ein Standfuss fehlt, und einer ist locker. Offenbar ist er von innen mit Gegenmutter verschraubt; ich bekam aber das Gehäuse nicht auf, um ihn festzuziehen. Eine Sicherung fehlt. Es handelt sich um die 220V-Version. Fehlerbeschreibung:Der rechte Kanal funktioniert einwandfrei; der linke ist völlig tot (auch kein Rauschen oder Brummen) Versand möglich ab Deutschland oder Schweiz. Abholung möglich in D-33803 Steinhagen oder in CH-9100 Herisau. Bezahlung möglich bar bei Abholung/ Übergabe, oder über ebay Fragen beantworte ich nur, wenn sie in verständlichem Deutsch oder Englisch gestellt werden. Unverständliche Fragen beantworte ich NICHT, auch nicht nach dem Kauf!

The Hafler DH-200 is a powerful stereo amplifier that will be at home with any budget savvy audiophile. In 2011 it was rated in The Absolute Sound as one of The Ten Most Significant Amplifiers of All Time. Paired with a quality preamp, it has the guts to drive the most demanding speaker systems (like a college roommates Dahlquist DQ-10s). As for this particular Hafler, it is running strong and still delivering the goods. I am the 2nd owner, having acquired it from Good Vibes stereo, Champaign Illinois in 1986, and it was like new when I bought it. Hafler amps could be either bought assembled or as a kit. This one looks to be factory assembled, based on the high quality of workmanship and solder applications. I did have one bad cap replaced last month, but the rest is all original. The amp is playing well. It will still drive speakers to concert levels, and according to the audio tech that replaced the cap it is good to go. I however think a couple things will need attention in the very near future. The RCA inputs are well used, and depending on the plugs you have they can make for a loose connection. There is also a faint but noticeable hum when you turn the amp on. It did not increase with volume, and with any music playing is inaudible, but this amp used to be dead silent. Replacing the RCA plugs could fix that, maybe its another cap, or maybe something needs grounded better. Keep in mind that this amp is 40+ years old, so you should be expecting to replace all the caps sooner rather than later. Im sure as good as it sounds now, a recap would make it sound better. Haflers are super easy to work on and even a novice solder tech can do most of the work. With this being vintage equipment, I will guarantee it to not be DOA, but make no other claims to its longevity. Please bid with that in mind. Feel free to ask any questions.
