Finally at long last I have finished the recapping, re-lamping and 2SC458 transistor replacements, including all electolytic caps including the 2 big 10,000uf caps, as well as all the tantalum caps. I put it back inside the case and brought it up to the kitchen system, which consists of a pair of ADS LS-520's, TD-146 w/ DL-100 cart, and Marantz 5003 cd player.
Word is: I am truly amazed at how good this receiver sounds. The sound is exceptionally clean on all inputs, but I am especially impressed at how good the phono input sounds. There is an exceptional clarity I have not experienced before. Maybe it's the Natural Sound. I could play LP's all day and not get tired of listening. I'm not sure how best to describe it, but there is a transparency to the sound I have never heard before and it is intoxicating. It makes every record sound more alive.
However, there's one last issue, and that's a speaker thump at power off. It wasn't as bothersome with the Rectilinear HighBoys I had them hooked up to in the workshop. But with the ADS's it's pretty much in your face.
What should I look for here? The DC Offset etc. have all been set. From what I've been able to research thus far it seems the relay is not getting engaged in time when the AC shuts off? Maybe some transistor needs replacement? I would sure like to fix this, then it will be perfect.
