Does anyone have source where I could purchase a Manual or does anyone have a copy  they would share.

I recently purchased this and it does work great but it has so many features on it I really need some help with it. Thanks

Hello,

I am measuring DC resistance from center tap to one side as ~500 ohms, center tap to other side as ~300 ohms, so it is not centered.

I remember I got the similar unbalanced DC resistance measurements for Opus 7 output transformer as well.

Assuming EC92 phase inverter has -1 gain, I would expect center tap would be really centered on the primary of o/p transformer, otherwise output would be distorted (due to different amplitudes for each half cycles).

I am trying to understand the reason of this, it is unlikely due to an issue of o/p transformer as I see the similar measurements on two different radio models.

Thanks in advance,

Cuneyt

I have a problem with my 55 opus TS in that under certain conditions (while using external input) the speakers vibrate excessively at very low( including sub audio) frequencies. This can happen even at a very low volume setting.  Reducing the bass setting helps however also cuts the good sounding audible bass frequencies. I was wondering if anyone else has experienced this or can offer advice on the best way to fix it. 

thanks Stuart Matousek
