Denon 103 output out of balance

Posted 8th May 2012 at 09:19 AM by tabarddn

Hi, I have just received a 2nd hand 103, (decappitated my 1st one, yes I know I should have had it re-tipped)
Anyway the output is swung to the left. I have a 2 arm system, identical arms and a Clearaudio Beta S in the other) I use the Denon through a SUT and have swapped arms and the is no improvement. Is ther a way to rebalance the output after the SUT say with resistors. I cannot do it after the head amp as the Clearaudio uses this haed amp through a switch box.
Advice, and you thoughs please

Stepped Attenuator

I bought a stepped attenuator (actually, two of them) from ebay seller hanshare-electronics. As always with eBay, I was a little worried about what would show up.

I'm happy to report that this is a nice job. The included resistors are clearly labelled, and the documentation, while spartan, is sufficient.

The only negative is the rotary switch is a bit "clicky". Better quality units I've seen are more damped.

On the positive side, though, the resistor values are very elegantly selected, to give a smooth response of about 4 dB per step from -60 to -40 dB, and 2 dB per step from -40 to -3 dB. Having been-there, done-that, I can say that I'd happily pay the asking price to get those resistors sourced and sorted for me. Next time, I'd also pay to get it assembled. Soldering was more painful than I imagined it would be, and the pre-assembled units much neater-looking than what mine ended up as.
