    Hello, I am looking for some technical help from a good soul. I posted this thread a few months ago but no visitor seemed to have enough knowledge of tuner electronics; therefore this new attempt. FM reception on my HK 430 receiver stopped working after a couple months of perfectly fine...

    H/K PA2400 signature or signature 1.5??

    Hello, I have a question that I can not really find on the internet. I know people like both of these amps and are happy with them and so am I with my pa2400 signature series. Is it worth to upgrade the pa2400 signature to the signature 1.5? Would it be a good idea to bi-amp both? if so, what...

    Harman/Kardon 930 : dial won't light, bulbs ok

    Hi, Recently acquired this receiver. I can't seem to figure out why the dial scale on this 930 won't light up, despite the fact that all the bulbs are testing ok. It takes qty. of 7, 6.3v 250ma fuse-type bulbs, all testing fine. Anyone know this unit really well and/or had this problem...

    H/K Signature 2.1 amp double stumper question

    OK... maybe I'm just foolish but I bought a European 220V H/K Signature 2.1 amp (5-channel x 100W) with a 220 /110 up/down converter. Question 1) How dumb am I thinking that I might be able to convert this beast to 110V and use it without the converter? Question 2) Added to the task is the...

    Harman Kardon 930 Twin, Tuner lights on all the time?

    Just acquired a beautiful and functioning HK930 Twin. I use it almost exclusively for playing records, but the tuner dial lights turn off when it's switched into Phono or Aux. I realize this is supposed to happen, I guess to save energy and the bulbs, etc, but aesthetically the thing looks way...

    Harman Kardon 330b - Left channel is there but much weaker than right

    OK. I'm working on a nice HK 330b. The left channel is very weak. The only way I can get the channels to "balance" is to turn the right channel down about 85% with the balance knob. The sound is not distorted, just very, very weak. That's not good. Here's what I've done so far: cleaned all...
