<p>Hey guys, I purchased several E. H. Scott (and McMurdo Silver) receivers a few months back from the Mottern estate (he was an electrical engineer who collected ultra high-end radios). Due to lack of space (and time), I have 3 units that I just don't need, including a 1931 All Wave-12 receiver & speaker, 1940 AM/FM Phantom Deluxe receiver, and a pointer-dial Philharmonic receiver & amp.</p>

<p>Hey guys, I purchased several E. H. Scott (and McMurdo Silver) receivers a few months back from the Mottern estate (he was an electrical engineer who collected ultra high-end radios).

<p>The All Wave is in amazing condition (no tears in the speaker), the Phantom has some surface rust on the chassis, and the Philharmonic looks good and is restorable / a few tubes are missing / all shields & cans are present, and there's some slight surface rust in spots.</p>
<p>If anyone is interested, just make me an offer.</p>

<p>I have a question regarding the chrome shields that cover the IF Coils on the Philharmonic. I need to remove these so as to replace the pair of capacitors in each one.</p>
<p></p>
<p>I removed (de-soldered) the grid caps from the pair of wires that exit the shield. I then pushed them inside a bit, but not all the way. I wanted to be sure I could pull them back out if the shield did not give way.</p>

<p>When I tried to lift the shield off , with plenty of force, it only came up a small amount. Is this because I must push those wires in completely (they still appear slack when I lift on the shield) or is there some under-chassis fastener holding these down?</p>
<p>I just don't want to force anything and regret it later.</p> Problems starting up a dead Scott Philharmonictag:ehscott.ning.com,2013-10-29:3925821:Topic:395842013-10-29T12:43:59.101ZKen Carrhttps://ehscott.ning.com/profile/KenCarr
<p>I am fishig for a few suggestions as how to proceed with my attempt to revive a Scott Philharmonic.</p>
<p>My photo section here on the group shows photographs that may be helpful.</p>
<p> </p>
<p>Background:<br></br> Rather than just plugging in the set as found, I elected to replace all of the capacitors in the power supply amplifier first and then try to slowly bring it up before moving on to the receiver.I also tested all power supply tubes and they all came back as in fine shape.</p>

<p>Background:<br/> Rather than just plugging in the set as found, I elected to replace all of the capacitors in the power supply amplifier first and then try to slowly bring it up before moving on to the receiver.I also tested all power supply tubes and they all came back as in fine shape.</p>
<p>I did the power up using a variac and an inline light bulb. All components were connected (P.S., Receiver, speaker). The result was that the light bulb glowed (brighter as I increased power) and the radio showed no sign of life, not even glowing filaments in the power supply.</p>
<p>Next I attempted to get the resistance for the input side of the power transformer. It came back as zero ohms. I did not disconnect the transformer leads when doing this. I also did a check on the filament leads from the rectifiers (power off) and got the same result at the output side. Of course I may be measuring something other than the P.S.</p>
<p>I then tried a few different hookups:</p>
<p>-All tubes in place, connect receiver to power supply only by the 4-prong on/off switch. I went up as high as about 50% voltage with no result.</p>
<p>- I the removed both 5U4 rectifier tubes and powered up again. The light bulb glowed but much weaker. Also the filaments lit on the four amplifier tubes.</p>
<p>- Then I removed both rectifiers and connected the 4-prong on/off switch AND the chassis plug to the power supply. Nothing came alive including the amplifier tubes. Again current was making the light bulb glow, a little brighter than in the last test.</p>
<p>- Finally I put the rectifier tubes back in place and made all connections (chassis and switch) except the speaker (did plug in a headphone set). Nothing happened except lighting up that bulb again.</p>
<p> </p>
<p>Also, the upper left section of the receiver chassis (where the chassis plug exits) has a large 2,000 ohm power resistor gray in attached photo) hanging and attached to nothing. There are a couple of wires there that are attached to big solder blobs that are not anchored anywhere. Something was 'repaired'. If anyone has a good photograph or two of this area so I could see the original wiring, that would be helpful.</p>
<p>Thanks.</p>
