"Ken- The serial number is L-430.  The radio is an attic find from a villa in the upscale part of Prague.  Please check your inbox from May 3.  Kind Regards, Jiri"

"I would love to get the serial number. The cabinet is reminiscent of a jukebox to me. Not a horrible price, that translates to about $400 USD. Unfortunately, it is in the wrong location."

How to select non-noisy tubes?

My FM Philharmonic is getting noisy.  All tubes test good and non-microphonic.  I have a stash of replacement tubes and I wonder what is the best strategy for selecting "quiet" tubes.  The audio section seems to be OK so the noise may originate from RF section.  Specifically, I wonder where to start replacing, what tube maker or tube tester results should I use, and whether there is some kind of a rig I could make to test tubes for noise out of the radio. Thanks, JiriSee More

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

McMurdo Silver / Jensen 18 inch speaker

Posted on March 15, 2018 at 6:10pm 2 Comments

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. 

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.

These resistances…
