General Information / Trouble Shooting Help
« Last post by mcb on June 12, 2018, 06:11:31 PM »
Recently the SPDIF in put on my KDAC stopped working.  The sound of silence was not good :'(

As my dac is fitted with one of the Scott Thomson boards, I swapped the input back to the I2S input (and changed the jumper settingsa) and all was well.



After some more exploring, we narrowed the issue down to the DAC and not either the transport nor the cable.

I then took the KDAC to one of the local tech's to have a look.  He has established that it is the board and not the RCA nor connectors to the board, however he was unable to help any further as he has no knowledge of the board.

So can anybody advise where I can get a wiring diagram from, or provide any other pointers on how to identify and resolve the problem

Regards

Murray

A picture of the stock underside except the 100R green resistor is gone replaced by a choke.

Picked up an immaculate standard leak Stereo 20 with all original insides. I can now see what they used as standard parts. I think this is the only original one i have seen. I had to put on the new speaker terminals. The standard ones are useless. It was really important the see what parts leak originally used and now i know.
Unfortunately i had to rebuild some of this new leak because age has damaged some of the electrolytic capacitors and resistors but of cause i used Allen Bradley 2 watt and Jensen electrolytics. But i will keep every original part intact where possible.

I needed to try the Vintage 1950/60c English TCC oil Capacitors. but it proved to be a non event, i think these 4 had problems and the amp sounded distorted, But i have plenty more so i will try again soon with a another set.

These are supposed to be the end game in valves, and certainly the most expensive. Yes its the world famous Western Electric 300B engraved base made in the 1930s. Not the later variants. These two are new and mint in the box. What do they sell for. I have seen these on eBay for as much as US$26000 a pair. I am going to sell them, but not for that idiot money. Any takers. Why do people pay such silly money even if they are incredible, who knows
