<p>The pot metal cast parts that support tuning capacitors are cracked in my unit. I wonder what can be done to fix it. Has anyone tried 3-D printing or is there another way? Thanks, Jiri</p>

<p>Does someone please have a good scan of the tag that came with the FM converter, as well as the tag dimensions? If yes, I wonder whether it could be please shared. I need one and I am considering placing an order for a replica. Thanks, Regards, Jiri</p>

<p>I had to ask a friend to do me favor and make a copy of a paper published in Scott News in 1994. This "new" Scott News were published in 1990's. I wonder whether the issues of "Scott News" have been scanned and saved somewhere. My internet searches were futile. Thanks, Jiri</p>

<p>So I finally found an 18" speaker for my Masterpiece V in Clifton cabinet. The original speaker is most likely in Japan, courtesy of a greedy seller. </p>
<p>The MP5 amplifier in my radio has a six-pin socket for the speaker cable, and the speaker I have has a cable with six-pin connector as well. What concerns me are the measured field coil resistances - 3410 Ohms between pins 1-6, and 365 Ohms between pins 3-6, respectively. Both coils are connected in series.</p>
<p>These resistances…</p>

<p>These resistances differ significantly from corresponding resistances for the 5-pin connector, Masterpiece VI speaker that are 8000 and 680 Ohms, according to what I found on web. Am I missing something or were the field coils for MP5 and MP6 speakers different?</p>
<p>Any help will be greatly appreciated.</p>
