05-05-2008 | | Check out how the servo system is designed. If there is a tachometer generator either integrated in the motor or at the capstan shaft, then the speed will be way too high if the servo amplifier doesn't get any signal from the tach. Typically, DC servo mo |

05-05-2008 | UDM3 transformer | Hi everyone.
I'm new to this forum and would first like to say that I'm hugely impressed with the level of knowledge evident here.
I have a problem with a Denon UD-M3 cd/receiver unit and as usual, Denon don't seem to want to know about it.
Basical |
05-05-2008 | | Not familiar with the specific one but, I have been able to repair very many transformers(including Denon's) which only had an open fuse in the primary. It may take some time & sometimes may not be possible (if that is what you have?)

05-05-2008 | | Thanks vtech, I do have a few other Sony slv-900 series service manuals to look at.
I'll post how I made out. You could be right though about the heads being worn, there are many , many hours on this unit.
Thanks again, Gary |
05-05-2008 | | Replace C928 1000uF@50V near the vertical IC. |
05-05-2008 | | Hate to say this but it's probably cheaper and easier to buy a new one. |
05-05-2008 | | Usually that mean the splitter is bad, #259296. |
05-05-2008 | | Thank you so much for your help vtech! I'm sorry I haven't replied sooner, I've been out of town for the past few days. Anyway, I appreciate it! |
