hafler dh-110, used great working order, some paint/cosmetic issues.I have owned it since 2005 and always kept it inside a climate controlled home with no contact with weather, but it does seem to have some very light rust or other patina/paint damage. I used it for 3 years and then got a tube preamp and have only kept it around as a backup since. It only has three rubber feet. I thought about replacing all three with four new ones, but figured in case they are original and desired by the next owner I would let them make this call. Please feel free to reach out if you have any further questions.

Hafler preamp, flea market find. Note there are scuffs and other cosmetic issues, and some of the lettering has chipped away so its hard to read in a few places. 4 cover screws on the bottom edges are not original. Do not connect this to an amp without repairing it as it could damage your equipment. I got it to work for a while, but the treble control was glitchy even after cleaning. Seemed to work OK with the tone disabled. Then it quit working through the RCA line outputs and tripped the protection on my amp. It still worked through headphones, Phono 1/2, Tape 1/2, CD, and Tuner inputs all worked. Sold as is for parts or repair.Free shipping to the US lower 48.

Hafler DH-110, Stereo Preamp original operation manual. Filter feature operation button not workingOn Jul-12-23 at 21:57:01 PDT, seller added the following information: Update 20230712: On audio inspection, the line amplifier section for right channel is low in output. The phono preamp is balanced on tape output. So the issue is either in the line amp or one of the protection or muting circuits. I am an electrical engineer and will inspect further in the office tomorrow. On Jul-14-23 at 15:54:28 PDT, seller added the following information: Update: cleaned RCA style terminals on back. Cleaned ribbon cable connectors to main pcb. Tested to full rail output to the point of clipping to verify balance regulation. Sine wave, square wave, 20Hz to 40KHz all look balanced and clean now. Going to repeat the listening test soon to verify balance on music.On Jul-14-23 at 16:17:02 PDT, seller added the following information: Music is balanced and sounds great. So the update from 2 days ago no longer applies and it just needed the cleaning I did today. Balance, tone control, mono switch are working great.

This listing is for a Vintage Hafler DH-110 Stereo preamp. I am selling this AS IS for Parts repair because it needs some attention.

Due to the age I would recommend having it checked out by a qualified technician. Please look closely at the photos. What you see is what you will receive.Sold AS IS. No Returns accepted. Shipping will be a flat $25 to the lower 48. Thanks for looking!

This DH-110A factory assembled unit (s/n 8208872) was bought new by the seller in the early 1980s, is cosmetically very good, and was fully functional when removed from the audio system in 2020 (then stored in a heated room in the shipping box). In 2019, knobs and push-buttons were professionally cleaned and de-oxidized to silence scratchiness, several capacitors were replaced and all RCA connectors were upgraded. The unit will ship in the original box with manual. Audio hobbyist groups on the internet note that this model of vintage electronics has a high incidence of scratchy sounding controls. The specific unit for sale here has quiet controls now after the 2019 servicing but scratchiness is likely to recur. Given its age, the unit is being sold “As-Is” so please ask questions before purchasing. The seller recently listened on the “Tuner” and “AUX” inputs with clear sound on both speakers and headphones and no apparent problems. All lights illuminate. Notably, the DH-110 includes two switchable phono inputs to allow a-b comparison of cartridges. A highly favorable 1982 review of the DH-110 by Julian Hirsch of Stereo Review magazine can be found online. Made in USA.
