It is a copper mesh that wicks away melted solder. I recommend getting some de-solder tape (radio shack probably carries it). Then heat up your soldering iron for about 10 minutes. The vertical board on the front is for the display.Īs far as removing/replacing the capacitor, you need to carefully identify the correct two leads from the bottom of the board. The main amp board is underneath and you probably don't need to do anything to that. The tuner board is the entire top horizontal layer that you see in the photo with the green 'supercap'. You probably need to be more careful that you don't break off any components, plugs, etc. The others drain pretty quick and/or don't hold enough charge to hurt you. Really the only ones that you might need to worry about are the biggest power supply caps (the tall black ones).

Maybe let it sit unplugged overnight before you attempt repair. Obviously you want to have it power off/unplugged when you do this. Same function hold the memory of CD's that I had a program for so I would not have to program each time I played it.īefore I get into this.is there anything I shouldn't touch? (As in fully charged capacitor) 47F 5volt that IIRC what mine said in my Sony CD player. They are usually close to the power caps as in the past they were very tall. Yes but chances are it will look nothing like the one Ken linked to. What sayest thou? Is it worth it? Should I bravely and resolutely forge ahead and at least try to locate the cap myself? I'm beginning to think that I'll just live with the lack of presets and manually tune each time just like an analog tuner. Both say it will be two to three days to research and then make the repair. Both say it should be an easy fix.one wants a $65 bench fee and the other wants $100. Regular updates to this site document recent investigations.įor an introduction, including lots of bell sounds to listen to, click here.I've contacted the hi-fi shop, as well as an electronics repair vendor. I have a growing collection of over 8,800 bell recordings with dates spanning 9 centuries, hundreds of founders and many countries which I use for ongoing investigations. Since completing the PhD the research has continued.

The full text of the thesis and introductory articles are available on this site. In April 2008 I was awarded a PhD by The Open University based on research into the musical acoustics of bells, and in particular the note we hear when a bell is rung.

The software is free and can be downloaded here. In the early stages of research I developed a software package ( Wavanal) which allows easy investigation into bell acoustics. This website describes investigations over many year into the sound and tuning of bells. And yet the way in which a bell produces its sound is complex, and even such a simple question as which note a bell sounds can have surprising and unexpected answers. Bells are ubiquitous even in our electronic age. The sound of a bell has the power to charm, to amaze, to warn, to frighten, and to lift the spirit. The bell is one of the oldest, and certainly is the loudest of, musical instruments.
