Hafler DH-101 parts f/s
I have an unfinished kit form DH-101. There are no assembly instructions so I don't know exactly how complete the kit is, and it's partly assembled.
From my light perusal there appears to be the preamp section board, perhaps a power supply board, top cover, front panel with switches attached, rear panel with rca's etc attached, and possibly a few other things. The DH-101 was a well regarded preamp of the mid 1970's designed by David Hafler of Dynaco fame. It has two phono inputs, two tape/effects loops, the usual aux inputs, a mono switch, bass and treble controls switchable out of the circuit. Some basic manufacturer's specifications (complete specs in the manual) Rated output: 3V 10Hz~100KHz THD: less than 0.001%, 20~20KHz at rated output IMD: Below residual of test instrument Hum & Noise: -90dB 1V Frequency Response: +0, -0.25dB 20~20KHz Bass control +/- 12dB @ 50Hz Treble control +/- 10dB @ 20KHz Phono Section: THD: 0.0006% @ 1KHz 3V output Slew Rate 12V/ microsecond Phono overload: 180mV @ 1KHz, 1.8V @ 20KHz Hum & Noise: 86dB below 10mV, 1KHz, A weighted Frequency Response: meets RIAA specification of 40Hz~15KHz +/- 0.5dB Gain: 34dB @ 1KHz Input impdedance: 47 Kohm in parallel with 250 pf (parallel capacitance can be modified) All discrete construction (no ICs) For sale to anyone who can use it, either to DIY something or to assemble a DH-101 or to repair or replace parts in one. For sale for $60. I will consider any offers. Paypal please, and buyer pays shipping. Update: apparently the owners/assembly manual is available online at http://www.hafler.com/techsupport/pd...preamp_man.pdf Broadly speaking from looking at the online manual it appears one could easily assemble the complete preamp from these parts, with possibly a few missing items sourced from the usual suspects or your parts bin. Post any questions or comments here or contact me via PM.

Just Personal Message (PM) me with your address and I'll send you a quote for shipping. I need the address to plug in the details before I can get a price from the website. I've sent a few things to Austraila; best way is Air Parcel Post. Usually pretty quick ... 7~10 days. To PM, click on my username and click the appropriate line from the drop-down menu.
