Is the relay really $80 or were you exaggerating? If it is, replace it with *anything* else that will fit. If you don't have something, I just might.

$79.95, no kidding, but including shipping.



a) There is an "anything else" in there now.


Yes, but I'm sure you could implement another "anything else" solution and have it look fine, work properly, and last indefinitely (elephant-snot glue notwithstanding).


b) I get a tested and warranted OEM part from the OEM maker. The warranty includes labor should it be necessary - 10 year.


A relay should last 50 years IMO. And while that warranty is impressive, I can't imagine how much trouble it would be to get them to cough up labor costs to replace it. Do they go on your word? Do you have to ship the relay to HK?


c) Made with "Matched Reeds" per the OEM spec.


Unless I was building a harmonium, I wouldn't worry about matched reeds....[rimshot] I refuse to believe that someone (anyone) could hear an audible difference between audio switched through an $80 matched reed relay and a $5 reed relay from Digi.

Just ship the board to Computer Components. HK is pretty much out of the legacy repair business. CC was their OEM supplier many years ago, and remain functioning to this day. I have to admit that is much of the appeal - how many such businesses remain viable, and how much is their viability, and the jobs they support, worth?

Especially considering the fact that in this particular circuit, the
audio doesn't go through the reeds during operation! The reed
contacts _short_ the audio to ground when the power is off, is turning
on, or is turning off. The relay is "normally closed", and opens
(un-shorting the output) during operation once the power supply
stabilizes. When you're listening to music, the reed relay contacts
are out-of-circuit, open, not carrying current, inert, silent, and
out-of-mind

The only impact I can see from having non-matched reeds, would be a
slight difference in the exact timing of the un-muting (at power-on)
and re-muting (at power-off). Somehow I can't see a millisecond or
two of variation at those times, as being an issue.

Hmmm... In the Computer Components Catalog, this relay is between several mercury devices, but not marked as such. Might explain the price.

Some companies prey on audiophoolery. Ten buck peer foot wires, CD demagnetizers and all that.

When are the going to come out with a DVD rewinder ? I mean, for the guy who has everything...

done years ago. Google.
Why it was done I don't know, I hope as a joke.

Yeah, they were jokes.

More disconcerting are the fools that "saw" improvement in television images by use of an external power conditioner. While the conditioner made have had some utility as a surge protector, they had no effect on the picture, which is why most fools bought them.

The relay arrived yesterday. About 1" x 1.25" x 3/8" and weighs as much as two quarters and a dime (coins). Six pins. And, it has the original Harman-Kardon part number on it as well as the CCI part number.

With the new relay in place, the unit is now operating properly and reliably. What I took out, once the elephant snot was removed, was a 12V sub-miniature US-made relay on a 24V system. That it lasted 10 years is remarkable. I Looked it up. No longer made and the company no longer listed.
