Harman-Kardon / HK Stereo Receiver Parts / spares. HK 570i receiver electronic parts.

























*Note about parts / spares sales

* Our "parts units", parts / spares and related reference information are primarily archived for the purpose of restoration / repair of "Oak Tree Vintage" units first. Only if we do not have a "viable" unit in yet, either already in process or in line to be processed, that may potentially need parts from a "parts unit", will we release available parts for sale (even though they may appear as available for sale to the public). As many of you know, the restoration of a unit can be a long, time consuming process. We may "lock up" parts that we may potentially need in the restoration of a unit (and not necessarily get it marked 'Hold' or 'Sold' on the site right away). Parts are priced according to the "potential value" of the unit they can be applicable to (meaning the amount WE would be willing to pay for the part if that was all that was standing between us having a "shelved unit" or a valuable / sellable unit), time to extract, their rarity & their condition to name a few criteria and likely will be completely unrelated to the original cost / price of a part when it was currently available from the manufacturer.

Parts Photos; We get a number of requests for 'photos' of a specific part. Unfortunately, in most cases that is not practical as the amount of time involved in posting that exceeds the value of the 'unique' part. We will sometimes post photos of less 'unique' parts, if there is a greater chance of them being available in multiple quantities, or on a more 'repeat' basis.

Parts, general condition / circuit board condition; Most of our parts are from 'salvage / donor' units. While we don't sell parts that are 'known' to be bad, occasionally parts will need further adjustment, cleaning, 'tweaking', or in the case of circuit boards, may need old, conductive glue / epoxy further cleaned, and some 'common' parts / components such as, aging / leaky capacitors, parts whose values have drifted, and some epoxy transistors may need to be replaced due to 'green / black / furry' legs, or because those parts were marked as 'sold separately'. Some circuit boards may have 'tired' "landing / solder pads", or severed traces, or cold / bad solder joints which can require solder re-flow or 'jumpers'. Unless noted, circuit boards will be 'crack / split / break' free.

Parts pricing; Most of our parts price / value will be based on a few things. Firstly, we are in the restoration / refurb business, so we consider what we would be willing to pay for the part if we needed it (which again, is what the parts are listed for in the first place, "our units"). Secondly, the rarity / value of the unit the part(s) fit. The 'Tuning Knob' for a receiver that has a final value of $350 will likely be much less than the "Tuning Knob" for a unit with a final value of $1500 or more (a set of tires for a typical sedan will be $400 to $600. A set for a Lamborghini can be $16,000). Thirdly, the 'rarity' of the part. Forth, the 'condition' of the part. Fifth, the difficulty to extract the part, or success rate for extracting certain parts. Sixth; frankly it's a LOT of work and time to part out a unit. Most take 1 to 3 days of shop time to process. Not only the disassembly, but the 4-15 hours of pre-testing / servicing and just as time consuming can be the amount of time it takes to do all of the research we do and the info we list on many parts for cross-referrencing to other units that my use the same parts by scouring service manuals. On many circuit boards we will list every 'semi-conductor' which is also very time consuming. Lastly, every call or email for a part can require 20 minutes to sometimes over an hour of 'phone support', often (about 70% of the time) with me convincing the potential purchaser that they don't need the part I have to solve their problem.
Sorry to sound like a "whiner" about selling parts, but "time is money".

Shipping: Shipping on most 'small' parts if typically via Postal first class or Postal Priority for both domestic (USA) and international orders. Larger parts such as transformers and drivers (speakers) are typically via FedEx gnd.
Some parts sales such as those for empty 'speaker cabinets', empty 'component cabinets / covers / bonnets' and 'speaker grills' and most are 'doomed' from the start. Due to their size and required packing supplies, the cost of 'packing for safe transit' and shipping are commonly 'disproportionate' to their cost, typically nearly equal to and sometimes greater than the cost of the part.  Think about it. An empty speaker cabinet or stereo receiver case is essentially the same size as a complete one. Yes the weight will be less, but most of items that size are calculated on 'dimensional weight', not actual weight so are commonly just as expensive as shipping a 'complete unit'. Secondly empty component cabinets have to be packed to disallow breakage, typically requiring nearly as much packing materials as an entire unit. Speaker grills have to be 'sandwiched' between foam sheets in large, custom ordered boxes (all relatively expensive).  It is what it is....

A non-response to an email of phone call / voice message request for a part that we don't show on one or our pages, or is already marked "SOLD" will be typical. We simply don't have the time / man-power resources to respond to every query we get for items we don't show as avail. Most folks get that. Having said that, I / we may respond if we have information on a substitution or other useful information relating to it.

A non-response to an email of phone call / voice message request for a part (we may appear to have, but typically 'highlighted in Orange or Yellow'), likely means that we are still determining which parts we are going to need for the restoration or repair of one of our units. Again, the parts are first for the restoration of our units and secondarily for the public market. Since we list the parts available for ourselves, it is not much effort to modify the menu's for web publication, which in turn makes the reference information and occasionally the part available to the public. Frankly, publishing them to the web, in many instances, makes it easier for us to determine if we have the part for our needs as well. The alternative to all of the above would be to not offer them at all to the public, however most parts are available to the public for sale.  Also, parts requests can occasionally take time for us to respond to. While we may have a part listed, and we like to keep the website 100% accurate, occasionally a part will be 'used by us' or 'previously sold' and we by oversight, and we did not get the web listing marked "SOLD", or the part gets  'mis-placed' or 'lost' (laid down somewhere in the warehouse(s) and then it get's lost track of (that happens to our coffee cups all the time, then we find it months later with 'a good batch of 'penicillin' growing in it), so we like to 'lay eyes on it' prior to responding. Sometimes we just can't figure out which cabinet or drawer parts were assigned to (and we're working on a system for that one).

Some folks email / call and want us to respond either way / whether we have the part or not. Again, we simply do not have the time resources to do that. Our time must be utilized on the requests we can fulfill. 
Sorry for all the excuses, but that's how the 'system' (or lack thereof) works.
And, if you don't see it, we likely don't have it.
 Thank you for your understanding.

Most of these components are "take-outs" from stereo gear that for various reasons we 'chopped' and unless otherwise noted are in serviceable / working condition / shape!
   In the case of output transistors, they will be tested / checked prior to posting and once again prior to shipment, pots / switches will be 'cursory' cleaned, parts already missing / utilized from circuit board will be noted, transformers will be checked prior to posting. Filter capacitors  will be tested / checked prior to posting and once again prior to shipment and 're-conditioned' / 're-formed' if necessary.

Unless specifically noted, we do not typically sell 'component level' parts such as resistors, diodes, transistors, semiconductors, ic's / integrated circuit chips, ceramic capacitors, led's, bulbs, lamps, belts, etc. We do commonly sell circuit boards / cards which will likely come with those parts attached.

When we say "some parts "MAY" also fit", that does NOT mean ALL the parts listed 'WILL' fit, and unless we show specific info that a particular part DOES 'cross-pollinate', do not infer that it does or will fit. Only careful research and comparisons, on YOUR part with service manuals, service bulletins, other comparable units, etc., MAY indicate a POSSIBLE substitution. If your situation is 'critical', do not base your decision on information found on this or any other page of this web site and do your own research.

We DO NOT have your part unless the following conditions are met:

A) You HAVE SEARCHED our page(s) and HAVE FOUND the part you are looking for SPECIFICALLY listed on one of our pages or you have solid information that it's a 'bona fide' substitution for your part (unless noted already, we won't have any further info along those lines)
B) The part that you have found is NOT marked as SOLD or SOLD OUT.

If you do NOT see it listed after thoroughly searching the pertinent page
(likely the page you landed on originally),  
we do not have it,   
nor do we know when
it might come in,   
nor do we maintain "waiting lists" for parts,    
nor do we know who
might have it.

Sorry, but phone and email traffic for parts
we don't have listed or for parts that are already marked "SOLD" has become too consuming of time resources.

 We try to keep these pages 99+% updated.
If you don't see the part you are looking for, simply check the web page periodically as we never know what will show up each day. Thanks!!!!!

ALSO: When e-mailing be sure to include a relevant subject, ie: Brand / Model number / reason for inquiry in the 'SUBJECT LINE'.
lines left empty, or with 'single word' text like;
"Hello", "Hi", "parts", "stereo", "inquiry", "question", "selling" or similar or similar 'un-qualified' terms may automatically be deleted by Anti-Virus / Spam settings or receive 'Low Priority'.
(Subject lines left empty show up as "No Subject" and are deleted automatically by our anti-spam settings".
We do not return calls / emails for requests for parts we don't show / or have available (we may choose contact with further, useful information).
