Schematic needed for a 25 year old radio

[Dan Street]

If anyone knows how I can obtain a schematic for a Harman/Kardon Model
HK-380i

receiver, I sure would appreciate your letting me know. It's a solid state
AM/FM

stereo receiver with a 50 watt RMS per channel amplifier, manufactured
around 1982.

Thanks in advance for your help.

I have it. But before I send it to you let me know whats wrong with
this unit and what you have checked on it already. I don`t like to
give schematics out to people that don`t know how to use them. So the
more you tell me that you know then the better it is for you.

What is wrong with the unit? I have a .pdf scan of the manual but it does
not have a schematic. If you need the alignments or block diagram only it
might be useful.

Thanks Leonard,
I inherited the Model HK 380i from our son and would like to restore it. He
apparently had it worked on by someone who butchered it, but it seems to be
a fine piece of equipment..

I know the 4 power transistors and shorted/open and have ordered the NTE
replacements. A dual 0.33 ohm, 3 watt resistor is missing in one channel
(but present in the other channel... that's how I knew the value) and a
couple of driver transistors are missing. I have no clue as to what kind
they are. I've checked with Harman/Kardon and they don't have service
manuals this old.

Other than that, the FM/AM works up through the discriminator and operates
the dial pointer, which indicates received signal strength.


The maunal would be helpful with the block diagram. I appreciate your offer
and would like to see the manual.

Free download and you don't have to prove you know what you are doing.

I think Harmon Kardon pulled their schematics from their website one or
two years ago. I'm sorry that I didn't download them all first, but
it's rare for things to disappear from the Internet.

Yeah, really sad when they provided them at one time but for whatever reason,
they decide to withhold significant information. But, I guess since it's their
data, they can do with it as they wish.
Still sad.

They still provide online access to manuals and schematics to dealers and
authorized servicers. This particular manual is avaialable on their site,
which is impressive since most companies don't bother to go back and scan 20
year old manuals. They must have missed the schematic, however, because it
is not included. This may have been one of the models that had the
schematic packaged with the unit, but it is not in the files for the OM nor
the SM.

Sorry, I did not really look at it. Many of the HK manuals do have the
schematic included.

HK did pull the main page. However, if you know you model number you can
get the manual by replacing the hk3801 in the link I provided with the
model you are looking for.

H. W. Sams lists it as available as a photocopy. Their electronic
index doesn't say if it was in one of the MHF series manuals as well.

Five days ago I sent you an explanation of what is wrong with the unit and
what I had already checked, as well as what I suspect is wrong, my
qualifications and my need for a schematic.

Since then, I have heard nothing from you.

What kind of game are you playing, tvguy?
