		<title>Battery replacement on Yamaha FS1R</title>
		<description><![CDATA[Yesterday my FS1R came up with a &#8220;Battery Low!&#8221; warning, after I had already done the replacement on my M1R and TX802 one year ago. Fortunately again, the CR2032 button cell sits in a holder. Note the Sanyo LC78834 DACs.

		<title>RNC 1773 repair</title>
		<description><![CDATA[Five years ago I ordered an FMR Audio RNP 8380 preamp and RNC 1773 compressor bundled with a Funk Logic FRT-8373 rack tray from Mercenary Audio. Mercenary is located overseas from me, as I live in Germany, so the weak Dollar in relation to the Euro was the main reason to order directly from the [...]]]></description>

		<title>Freshman&#8217;s 01/W refurb</title>
		<description><![CDATA[The following is a set of photos from Freshman&#8217;s  01/W refurbishment. In fact, his 01/W suffered from the &#8220;no sound&#8221; syndrome, the &#8220;sticky keys&#8221; syndrome, lots of sluggish panel switches and a dim display. Freshman fixed it all in one repair, which took several days, but in return his 01/W now operates like brand [...]]]></description>

		<title>Lautsprecherschalter</title>
		<description><![CDATA[Als Bastler ist man oftmals geneigt, sich zu verbasteln. Kleine Dinge werden dann groß, und einfache Dinge werden kompliziert. So kam es, dass ich kürzlich für einen schlichten Lautsprecherschalter nicht weniger als einen Microcontroller und vier Relais verbaut habe.]]></description>

		<title>Korg 01/W &#8220;no sound&#8221; repair</title>
		<description><![CDATA[A few weeks ago <a href="http://hajo.kessener.net/electronics/korg-01w-sticky-keys-repair/">my 01/W</a> started sounding "hissy" and distorted, and the output level dropped audibly. After a short power off it recovered without further action. But then, on the next day, all analog outputs were dead.]]></description>

		<title>Torwarnleuchte</title>
		<description><![CDATA[Ein Bekannter benötigte für sein elektrisch getriebenes Hoftor eine Schaltung, die den Warnleuchten beim Öffnen und Schließen des Tores zu einem auffälligen Blinken oder Blitzen verhilft. Nun hatte ich mir gerade wenige Wochen zuvor einen AVR-Programmer gekauft und auch meine alten Ätzutensilien wieder herausgekramt, womit eigentlich nichts näher lag, als hierfür mal schnell eine kleine [...]]]></description>

		<title>Battery replacement on Korg M1R</title>
		<description><![CDATA[My M1R came up with a &#8220;battery low&#8221; warning, just a few months after I did the replacement on the TX802. Possibly these oldies start a conversation on their sicknesses each night after the boss has gone to sleep. The CR2032 button cell is sitting in a socket, so there is not much to tell [...]]]></description>

		<title>Battery replacement on Yamaha TX802</title>
		<description><![CDATA[My TX802 started behaving like it was broken: strange characters on the display and strange sounds. Not even a factory reset and a following sysex dump helped to remedy this situation. Although there was no &#8220;battery low&#8221; warning, I first replaced the 20 years old battery before going on with error search. It turned out, [...]]]></description>

		<title>Hammond B250 repair and cap replacement</title>
		<description><![CDATA[Recently, after having visited the Tasten-Festival at Herdecke, I felt inspired to sit down on my Hammond B250 and move my fingers. This sadly happens seldom enough, and so the organ hadn&#8217;t then been powered on for months. And although the B250 is a quite reliable oldie in my experience (just one repair within the [...]]]></description>

		<title>Reparatur eines LG 1811B TFT-Monitors</title>
		<description><![CDATA[Im Sommer 2003 gönnte ich mir für damals soeben erschwingliche 749,- Euro pro Stück zwei TFT-Monitore LG 1811B mit augenfreundlichen IPS-Panels. Seitdem haben die beiden Geräte &#8211; betrieben an einer Matrox G550 DH Grafikkarte &#8211; jeweils fast 12.000 Betriebsstunden auf ihre Uhren geschrieben und machen dabei bis heute ein gutes Bild. Vor einigen Wochen schaltete [...]]]></description>
