This is a vintage Hafler (made in USA) DH-200 stereo power amplifier in good working condition. I am the second owner, and have had it for several years. The original owner told me it was a factory wired unit that he purchased new at a dealer. These amplifiers have an excellent reputation and compare favorably to modern amps: less than .02% THD at any power up to 100 watts with both channels driven, 20-20,000Hz. IM distortion is less then .005 % under the same conditions. Sold as is because of age. Parts are readily available for these as you can see on here. People frequently modify them, but as noted above the original factory specs are excellent. This was in regular use until several weeks ago. The included manual is something I downloaded and printed off the web. Shipping will probably be high, it is 26 lbs. and will be well boxed.

Hafler DH 200 Stereo Power Amplifier Made in USA 600 WATT MAX. TURNS ON but hasnt been tested some cosmetic wear and bent fin as seen in pictures.

This Hafler DH 200 stereo amplifier delivers an exceptional audio experience. With 100W of power, this amplifier is perfect for any music enthusiast. The amplifier has been serviced and fitted with new caps to ensure that it is in top working condition. The two large old 10,000uf 75v electrolytic capacitors replaced with new Cornell dubliner 30,000uf/75v these caps alone will cost you $160 alone at dig key , the non polar dc blocking capacitors are nichicon MUSE capacitor and the 220uf/80v electrolytic capacitors , important high wattage resistors are vishay quality ones , the bias adjusted to conservative 230 mA for cool running . New on/off switch installed , the output MOSFET transistors are all original factory matched made by Hitachi there are total of eight of them . The old white grease in output transistors was cleaned out and new better grease installed for cool running and better performance After the above recent service was performed the amplifier was tested and it’s produces truly awesome sound! YOU WILL ??LOVE IT1 Payment is required within 24 hrs of auction end. NICE! FRIENDLY! AND SERIOUS! BUYERS ONLY! No scam artists buyers that harass sellers , please! Thanks! eBay is suppose to a nice place to buy and sell. Thanks for your purchase and for your business both of which are greatly appreciated!

HAFLER DH-200 STEREO POWER AMPLIFIER As can be seen from the photos, this unit is for parts or repair---hoping to pass it along to someone that can either use parts from it for their amp(s), or who feels up to the challenge of getting it up and running again---I have no idea as to what the history of this amp is, as far as past operating condition---I found it just as it is, and what you see is what you get, just as seen in the photos. Payment must be received within 24 hours of end of listing. Will ship via FedEx within one business day of completed payment, very well packed and fully insured. Guaranteed to be as shown in the photos and as stated in the description, but thats it, no other guarantees or warranties whatsoever--this amplifier is being sold as-is, for parts or repair. Any questions at all, please just ask...thanks!

Audio by Van Alstine Omega III 250 based on Hafler DH 200. This is a later version of the complete rebuild by Audio By Van Alstine. I have recapped the unit with the exception of two non polar caps. The grounding scheme has been redone using a five lug terminal strip. Fewer wires thus go to the ground buss wire between the two big caps, a source of hum. The big 10,000 mfd caps are from Dynaco Dan. Smaller caps are Nichicon, 10 caps were replaced. The case looks good from the front, there is some old shipping damage on the back of the fins on one side, some damage to the same side bottom of the case. The bottom damage was (mostly) flattened with some wood blocks and a big screw clamp. I had this in my system for several weeks, very impressive amp which deserves the best preamp, speakers and sources. This sale is the the lower 48 states only. I will not sell or ship overseas. I have a heavy duty double box for the item, the fins will be protected with cardboard surrounds. The amp will be bubble wrapped and tight in the box but with flexible packing materials. On Sep-07-23 at 04:56:46 PDT, seller added the following information: Added note: Bidders should be aware that the amp produces a low-volume zing sound through one channel on shut down. This is common to other AVA conversions of this amp. Recapping did not eliminate this quirk. The B+ and B- voltages are 61 volts, zero DC at loudspeaker terminals. I left it on all the time. The power cord has been replaced with a much larger polarized version.

Recapped with 105C capacitors, nichicon muse for the input capacitors There is a 100uf buffer capacitor for the power rails, right at the MOSFET output devices themselves. This is good, as the original design has the rails fused, and then the rail voltage goes to the MOSFET devices.This layout causes odd harmonic distortion to spike as the fuse element fluctuates dynamically (all odd order harmonics when fuse elements are in use) , and then the feedback circuit is constantly compensating for this. This is bad. very bad. It makes for false gritty high frequencies and detail, due to the constant micro correction of odd harmonics by said feedback network. TRo fix that, or mitigate it tremendously, I put those 100uf, 100V capacitors right at the output devices themselves. Youll see them right behind the circuit boards, between the circuit board and the Heat sinks. the rest of the capacitors are 105C capacitors are are, of course, orignal uf values. the main power supply capacitors come from a low hour but dead Panasonic Ramsa wp-9220 200 watt per channel power amp, which had tremendous current drive, relatively speaking. These capacitors are probably Elnas best and are probably from their own audiophile range of capacitors. They are totally non magnetic, indicating that they tried their best to make their best capacitors, for audio. These capacitors (measured) have tremendous current capacity, and very low internal impedance. They measure the full rated 20,000uf each, which is actually kind of unusual, of youve ever spent time measuring capacitors. Some amount lower than spec is what is normal, even for brand new capacitors. For used capacitors to measure that crazy good, is unusual. So, not just some stock upgrade, but a high quality audiophile upgrade. This high uf measurement also means they have lots of life left in them. the originals were down below 4500uf each (rated 10,000uf), and were dried completely out. I painted the top and you can see where the label was taped over and then the paint around it. It had a little rust...so I cleaned that up with a light spraying. lots of dust so no white specks, actually. Photo makes it look that way. This is a nice sounding amp. Plug and play.

untested unfortunately it has light surface rust but honestly that bad please ask any questions before purchasing thank you for your interest
