			<content:encoded><![CDATA[<p>This is what the old girl looks like right now :</p>
<div id="attachment_213" class="wp-caption alignnone" style="width: 310px"><a href="http://www.paleoelectronics.com/blog/wp-content/uploads/2009/12/skylarkrust.png"><img class="size-medium wp-image-213" title="skylarkrust" src="http://www.paleoelectronics.com/blog/wp-content/uploads/2009/12/skylarkrust-300x128.png" alt="Skylark Faceplate with plenty of rust" width="300" height="128" /></a><p class="wp-caption-text">Skylark Faceplate with plenty of rust (click for fullsize image)</p></div>
<p>Now it&#8217;s not going to matter one bit if I don&#8217;t do anything about the looks, but it would be nice to get her cleaned up.   There is no way I am going to be able to clean around the silk-screened lettering or lines.    So the whole thing is going to have to come off.   I don&#8217;t even know how you clean these things.</p>
<p>Now, the chassis is actually just a single piece of metal, bent and punched.  I&#8217;m not sure if it&#8217;s steel or aluminum but either way, it&#8217;s easily bendable.<br />
Here is a picture of one out of the cabinet :</p>
<div id="attachment_41" class="wp-caption alignnone" style="width: 310px"><a href="http://www.paleoelectronics.com/blog/wp-content/uploads/2008/02/thevictim.jpg"><img class="size-medium wp-image-41" title="GA-5T on bench" src="http://www.paleoelectronics.com/blog/wp-content/uploads/2008/02/thevictim-300x200.jpg" alt="5T Chassis out of cabinet and looking from behind" width="300" height="200" /></a><p class="wp-caption-text">5T Chassis out of cabinet and looking from behind</p></div>
<p>So I suppose I could just have one remade.   That would surely cost more than the amp, but I&#8217;d come out of it with the specs for new metal, which would be a good thing for anyone else trying to do this.  Then I would need to get the art redone or redesign something.  Again.. favors or money and no improvement in the sound.</p>
<p>I&#8217;m leaning towards leaving it, for obvious reasons, but very early in the process I&#8217;ll have to make the decision..  anyone have any thoughts?</p>

			<content:encoded><![CDATA[<p>I spent about 10 years doing all my playing direct into a computer or a headphone amp.</p>
<p>Finally, I crawled out of the shell and started looking for an amp I could play at home at night and also in a studio/practice situation.  I settle on the <a href="http://www.songworks.com/">&#8220;Lil&#8217; Lanilei&#8221;</a> by Tris at Songworks.  However, that took some eight weeks to build and I was getting antsy &#8230;</p>
<p>Then I read about Clapton using the Gibson Skylarks in the studio.  A little research turned up some interesting points:  They sound great, are damn cheap and have very simple circuits.</p>
<p>Turns out the real &#8216;Class A&#8217; single ended Skylarks are not so cheap.  <a href="http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&amp;rd=1&amp;item=290161607791&amp;ssPageName=STRK:MEWA:IT&amp;ih=019">This one</a> went for $255 + 40 shipping and that is as cheap as I&#8217;ve seen one go in a long time.   400+ is the usual.  They look like this :</p>
<p><a title="Pre-Crestline Skylark" href="http://www.paleoelectronics.com/blog/wp-content/uploads/2007/09/skylark_1.jpg"><img src="http://www.paleoelectronics.com/blog/wp-content/uploads/2007/09/skylark_1.jpg" alt="Pre-Crestline Skylark" /></a></p>
<p>After a couple of weeks on ebay, I found two 60&#8242;s Crestline GA-5&#8242;s (well, one GA-5T (Tremolo) and one GA-5).  These are both Gibson &#8216;Skylark&#8217; amps, but not likely the kind used by Clapton  They each cost 200 with shipping and both arrived with significant hum.  New, they looked like this :</p>
<p><a title="Crestline Skylark (GA-5)" href="http://www.paleoelectronics.com/blog/wp-content/uploads/2007/09/skylark_21.jpg"><img src="http://www.paleoelectronics.com/blog/wp-content/uploads/2007/09/skylark_21.jpg" alt="Crestline Skylark (GA-5)" /></a><a title="Crestline Skylark Tremolo (GA-5T)" href="http://www.paleoelectronics.com/blog/wp-content/uploads/2007/09/skylark_2.jpg"><img src="http://www.paleoelectronics.com/blog/wp-content/uploads/2007/09/skylark_2.jpg" alt="Crestline Skylark Tremolo (GA-5T)" /></a></p>
<p>As the GA-5 arrived first, I worked on it first.   I removed the old speaker wire and added a longer run of real speaker wire, and I replaced the power filter capacitors.   That amp rocks.  Simply fantastic clean at low volumes and great 60&#8242;s crunch as you turn the (only) dial.  The other &#8216;dial&#8217; is the on off switch.</p>
<p>The other one still has a nasty hum.. I&#8217;ll start telling that story soon.</p>
