Hello,I'm currently uing this vintage ReVox B226 cd player as my main source. There's room for improvement (i'm planning to have a new clock installed, as well as new op-amps or a univesal tube output stage), but it sounds great as it is - musical enough to be enjoyable.
I've been using it for about a week.
However, it's a 30 years old machine, and altough the CDM1 mechanic reads flawlessly, it seems to have developed a problem in the logics section: every once in a wile, very randomly, it sets itself in "standby" mode. There's no distortion, no noise, or anything that could let believe to some other failure; it just goes in standy mode. Once it even popped "ON" without me doing anything. In any case, i just turn it back on and it works flawlessly again. It can stay on for hours without any problem, and sometimes it would just go to standy after just a few minutes. It doesn't seem to be temperature-related.
Would it be a mechanical failure somewhere behind the "buttons", or is there a capacitor somewhere that could cause the culprit? all caps are still the original ones, including the Frako in the PSU section... :/
any advice would be greatly appreciated; besides that problem, it's a fantastic machine and works amazingly good.

Fair chance that it would Cost significant Coin to patch.
IF it even could be.
You may find that a current machine may sound markedly different,more than a reasonable chance it will be an improvement.
Get one.. while a few are still being sold.
Failing that a DVD machine can work v well too.
Oppo owners lover their gizmos for CD.
There could be a dip in voltage which is causing the player to turn off the power. It could be something simple as cold soldering in the power supply section or something causing a short circuit or a component overheating. The best way to fix it is to first download a service manual and find an experienced technician. Below is a link to a Revox B226 service manual in German.

A very tough culprit to track down. Do you have a vintage electronics tech near you?
I have a computer like that. I think Power supply noise could be the problem. It could be hard to localize though.
