    Ugliest Receiver Made

    But I want one. I would buy it on the spot if it was available in Poland :) Even if just for scaring the hell out of small kids :)

    Harman/Kardon 730 Twin Receiver - CL find, right channel problems

    I would check SPKR switches, it also drops out channels on my 730.

    HK 930 Bias adjustment.

    There is no point in DC offset adjustments before caps at least in the power sections are replaced.

    Vintage Harman Kardon / 2 Phono Inputs

    My HK 730 twin powered receiver also has two phono inputs. And because I have no turntable, I bypassed the phono stage thus now I have two more line inputs :)

    Nikko receivers

    Not quite sure that you guys know it already, but NIKKO Hi-Fi RECEIVER R 850 comes from Poland :) http://unitra.eu.org/node/367 I owned AT9100 many years ago (in the 80s last century) -- fine sound, but its SNR was somewhat low (48 dB on tape input, SNR increased greatly when one was using...

    Capacitors with 3 leads?????

    Bass "popping" in H/K 730

    Frankly I don't quite remember, but I'm almost sure I used Vishay brand http://www.madral.pl/dok/eyn.pdf Also some Panasonic FCs. I did almost full recap, except for few caps (4 or 6) in the tuner section. I had almost no problems recapping, but two caps in the power amp are hard to access, they...

    Bass "popping" in H/K 730

    I did a recap of HK 730 this year and all I can say that do not be afraid to use (almost) any other cap brand. Just use caps with low ESR (labelled often "for audio") and in the power section use caps with higher voltage (they have lower ESR in any way). You can also use caps with higher...

    HK 6900 "protection circuit" tripping?

    I'd rather start with replacing caps in the power rectifier, before touching any offset/bias pots -- often leaky caps cause asymmetry in the voltage provided for power amp board, and this causes DC offset.

    HK 450 (new to me) problem

    My HK 730 experiences the same phenomenon. I don't think there is much to worry, before and after recapping it was the same. With that much capacity to charge, transient time is quite long.
