<p><strong>A REALLY nice 16, I bid to $750, went for $770.</strong></p>

<p><strong>Yes I did replace the caps in those cans. Not too difficult. The surprising thing was the resistors were all withing tolerance , except the two that overheated. That's pretty amazing.</strong></p>
<p><strong>I'll get back to the tubes in future.</strong></p>

<p>Suggest you at least try metal 6J5s to see if the hum reduces.</p>
<p>Also, regarding caps replaced, did you dismount these two assemblies inside to replace caps inside:</p>
<p>- the RF diode (back apron) ? and</p>
<p>- the IF diode (between the socket for the 3rd IF and the middle partition ? </p>

<p>6J5's normally have pin 1 connected to the metal shell. You would certainly have to make sure that pin 1 is not used as a tie point other than ground. The audio people have driven up the prices of good 6J5G's.</p>

<p><strong>Good call. <br/>I'll try that next time I play with it. Now have a couple tube Hi FI amps to do for someone.</strong></p>
<p><strong>I am out of 6J5 G tubes and they are pricey. Have 6J5 metals but not going to use those, not sure if the case goes to a pin and if said pin is used for a tie point.</strong></p>
<p><strong>I now see an AllWave and a Philharmonic I will bid on Saturday.</strong></p>

<p>The first AF (1st audio audio) tube can be a hum source - as per the Owners Manual. Swap other 6J5's into the 1st AF tube socket. So start there.</p>
<p>Scott evidently was using Sylvania "G" tubes starting late 1930's. But try any other 6J5 tubes you may have.</p>
<p>I had the RF tube cause hum in a Scott Super 12. Filament to cathode leakage can also cause Hum.</p>

<p>I have the same issue with my 16. So far, no luck finding the spiral wound tubes. Different tubes produce different amounts of hum - at least that's what I've found.</p>
