<DIV><FONT face=Arial size=2>Folks,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I ordered, received and built one of K5OOR's "SDR Preamps" (Model PA-100) which will act as a 5-8W driver stage to my 100W SB-104a brick amp I intend to use with Penny. O was asked to report back on my experience with that product. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial>General:</FONT></DIV>
<DIV><FONT face=Arial size=2>The kit I received contained all parts, the PCB was good quality and the instructions were sufficient to complete the assembly and bias the amp.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial>Details:</FONT></DIV>
<DIV><FONT face=Arial size=2>I completed kit assembly in about 5 hours. I rate the level of difficulty as intermediate. The most difficult steps in the assembly were winding the transformers and coils - but the instructions for winding those were better than I have seen in other kits. Beyond that it is pretty much plug, solder and pray. :) </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>The only "MacGyver work" was (oddly enough) adding the snubber diode for the T/R relay to the board. The diameter of the leads for the supplied part (a 1N4004) were larger than the through-plated component holes. I had to use remnant leads from other parts to complete that step.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>After the assembly, I was able to bais the amp (following written instructions that could be clarified a bit). The quiescent current was lower than what was noted in the docs, but the amp "biased" pretty much as decribed. </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>By the weekend I should have this driver amp integrated and will post another report. I was VERY interested in the post about poor audio using this amp as audio is inportant to me.</FONT></DIV>
