Hafler DH 101 Preamp in fine working condition great sound and looks.

HaflerpreamplifierDH-101 Has rare original solid wood and acrylic enclosure Made in New Jersey in the 1980s If you are reading this you probably know all about the quality and sound stage of this unit. Comparable to pre-amps that cost thousands more. Perfect for turntables! Great overall condition. Used for 5 years with no sound issues. sounded great on my turntable. Occasionally when turning on while amp is on the speakers will pop at first. I just turn this unit on first before the amp and have no pop sound. The Treble knob is very hard to turn but loosens up after a while. could be adjusted inside but i never opened it. Overall this unit worked great on my system but moved onto a McIntch pre-amp so Ill pass this on Sorry no returns because its an electronic devise, but rest assured it is in working order and you will love the sound.

HAFLER DH-101 Stereo Preamplifier Dual Phono Inputs, The face for the rack mount it a bit faded, was working 10 years ago, but unable to test. Feel free to ask any questions.

DAVID HAFLER DH-101 Stereo Preamplifier Dual Phono Inputs. Tested using my cellphone jack to RCA, then RCA to headphone jack for monitoring. Both channels work, there are some static noises when moving the controls which is probably typical for the age. Includes the original box. I will pack this into a larger box for shipping, especially as the rack mount panel is too long for the original box.

Hafler DH-101 Preamplifier with Dual Phono Stage Serviced For sale, we have a fine example of a Hafler DH-101 Preamplifier with Dual Phono Stage. This modest preamp with its two phono stages is a wonderful sounding unit. While the unit was in proper working condition when we acquired it, we recapped the power supply section with Nichicon modern electrolytics as preventative maintenance. All the pots and switches were cleaned, and then treated them with Deoxit F5 and D5 respectively. This preamp has been in use since it was purchased new by the original owner. It was paired with a Hafler DH-200 amplifier, and ran a pair of Dahlquist DQ-10s. Included with the preamp are the original assembly/instruction manual, promo sheet, and poster of the wiring layout. The unit was well cared for, there are some light scratches and blemishes, but the unit is in very good physical condition, and presents itself very well. See pictures for further details. We dont have the original box for this unit, but we take packaging and shipping seriously. We spare no expense and use heavy duty boxes, several inches of polyethylene foam on all sides of the unit, and use water activated, fiber reinforced tape on all seams.

this was an originally upgraded and complete DH101 that was tested, working, and ready to go. then I needed an unobtanium part from the Hafler. i then took apart this working unit and the parts are nowup for auction on eBay: chassis&covers, front panel, andin this auction, the circuit board. completely recapped - replacing those super old (40 Yearsold) electrolytic capacitors with modern-day selected versions. this includes replacing the old coupling caps with WIMAs etc topped off with a signature BLUE LED. it is time-consuming and tedious to upgrade caps in-situ. it felt like forever. however, using this board you unsolder each from the old board and solder that connection to thenew board. One at-a-time prevents mis-wiring. about 20 connections. this new board has two helpfulaids: 1) the original wire was clipped off to help you locate the solder joint, and 2) there is a black dot next tothe solder connection. No returns - I have no idea how skillful you are, nor how accurate you are in troubleshooting ifsomething goes wrong. However, if you use the eBay not as described to return this, you pay return shipping, and $100 as a restocking fee for me to troubleshoot what,if any, damage resulted. you could also use this board as the heart ofa new preamp, eliminating all those optionsthat were necessary in the 1980s like(external processing unit, tone controls,tape I/O, mono, etc). do note that if you do use this board you will have to find vol/balance, treble, and bass pots. Personally,I would eliminate the tone controls, wire in fixedbalance resistors, and use a high-quality ALPS volume control ( or Noble or...). thanks for looking

Beautiful condition! I listed as for parts or not working because I have not heard it yet. I was told that it works fine,but have not heard for myself. Fast free shipping to the continental United States only please. No returns please.

Up for bids is this nice vintage Hafler DH 101 preamplifier. This unit has been cleaned, tested and works great. The DH 101 was the first amplifier designed and built by David Hafler and is regarded as a hi-end classic. Even though this unit isn’t the actual first one built, it still a much sought after and rare classic. This thing sounds warm and clean. Don’t miss out on an opportunity to own a piece of audio history. U.S. shipping only. Thanks for looking.

This was given to me with the Hafler DH-200 Amp. I didnt try to set it up for over a year and when I did it wouldnt power up. I was told that it worked but nope. Im going to be buying a restored or working one after I sell this one for parts. The pictures are my description. The only thing I did was clean the pots.

The Hafler DH-101 Preamplifier has six inputs and three outputs that allow you to connect to various devices. Please note the following:1. The connector is not original equipment (see photo).2. The cable at the box junction has a small nick. A drop of liquid tape has been applied to protect the cable (see photos)4. Plugging the connector to an electrical outlet shows the LED lighting up; no other testing has been done.

This is a very well thought out and executed, yet simple, preamp. It supports 4 line level inputs (2xtape, tuner, and aux) as well as two MM phono inputs. It has bass and treble controls as well as a tone override switch. It supports output in stereo or mono. It has RCA ports to include an external equalizer if you wish, and supports tape dubbing mode. Has multiple switched and unswitched AC outlets to feed power to your other system components. Red LED power on indicator on front face.The operation manual and schematic are available free online and the amplifier has a strong classic following in online forums.

At auction is a Hafler Preamplifier DH-101 in all original working condition. This Preamplifier was in storage for years and, as a result, has suffered some cosmetic damage, i.e. light rust on the top of the case and some tarnishing on the RCA outputs (which should be replaced anyway) and knobs. (see photos) This surface rust can easily be sanded off and repainted. The face plate looks good, but does have a few scratches. I brought this unit up slowly on a variac and it performs well. Ive used it for several hours with a streamer though the AUX input and a turntable through the Phono 2 input and it sounds good. I have no doubt that, with a little TLC, this can be a fine Preamplifier. Guaranteed to be as described, or your money back; no questions asked See my other auctions for more! Thanks!
