<p>Hello-</p>
<p>I used the socket from a broken 24A tube to make an adapter plug to fit in the tuning meter 76 tube socket for the magic eye kit. This socket gave me filament power, the necessary grid connection, and B+ voltage. Then I used the existing ground lug on the chassis for the fifth wire and powered up the AW23 with the magic eye installed. And it works great! I am using a 6E5 in the socket.</p>

<p>Hello-</p>
<p>I used the socket from a broken 24A tube to make an adapter plug to fit in the tuning meter 76 tube socket for the magic eye kit. This socket gave me filament power, the necessary grid connection, and B+ voltage. Then I used the existing ground lug on the chassis for the fifth wire and powered up the AW23 with the magic eye installed. And it works great! I am using a 6E5 in the socket.</p>
<p>By using the tuning meter 76 socket, I was able to install this kit without adding any soldered connections to the chassis anywhere. Didn't even have to take the chassis out of the cabinet. Removing the magic eye will be as simple as pulling out the adapter plug and reinstalling the 76 tube! The wires coming from the plug even fit in the slot on the side of the original tube shield typically used for grid wires, so I was able to put the shield back in place too. Everything is completely reversible.</p>
<p>All I have to do now is figure out a way to dress the wires so they look better. The wooden 'case' I made doesn't match the original cabinet color as closely as I hoped, but have been making do with what materials I have around the house already. It does look closer in color in person than the picture shows though.</p>
<p>Thank you Mike and Kent for the advice on getting this kit installed! </p>

<p>You could remove the 76 tube completley and make up a plug to fit the socket, as all of the signals are there.</p>
<p>All you would need to find is a chassis point for the eye tube cathode, completely reversable with no modification.</p>

<p>For the yellow wire...connect it to the grid lead of the 76 tube that acts as the tuning meter amplifier. That grid is connected to the diode load (AVC). It should give good action on the eye.</p>

<p>Hello-</p>
<p>As I am due to be furloughed from work next week due to the major dip in aerospace manufacturing presently occurring, I am considering a new project with my AW23. I have obtained a NOS Amphenol Magic Eye Socket Assembly that will allow me to add an eye tube to the Scott.

<p>Hello-</p>
<p>As I am due to be furloughed from work next week due to the major dip in aerospace manufacturing presently occurring, I am considering a new project with my AW23. I have obtained a NOS Amphenol Magic Eye Socket Assembly that will allow me to add an eye tube to the Scott. I would not consider doing this except for the fact that it will be a non-destructive and completely reversible operation to the radio. </p>
<p>My plan is to route the wires through the existing hole in the chassis presently used for the dial lamp (there is enough room if I use plastic-insulated wires) and to make a wooden housing for the tube/socket assembly that will sit on top of the Warrington cabinet. I won't be drilling any holes in the chassis or cabinet. This will be connected via a detachable "umbilical cord".</p>
<p>Since I am unlikely to ever have a Philharmonic or other Scott that is factory equipped with a 'magic eye' tube, this seems like a reasonable substitute, especially because the original AW23 tuning meter is frankly uninspiring to look at.</p>
<p>But I have a few questions before I even attempt getting started on this project. Please note that I am including photos of the Amphenol instruction sheets for reference to what I am asking about.</p>
<p>-I understand all the wiring instructions _except_ I am not clear where the yellow wire should be connected in the AVC circuit. I do not know what point on the AW23 schematic could be called "the diode load" or, alternatively, points X or Z as shown in the photo of the sample schematic. Does anyone have any suggestions on this? See the photos of the instruction sheet for clarification.</p>
<p>-Is there any way to know which eye-tube would work better? According to the box, either the 6E5 or 6G5 can be used. I know these are not identical tube types and not directly interchangeable.</p>
<p>-Taking into account that I won't do this if it will cause damage or require any irreversible modifications to this radio, is there any reason that this is a terrible idea? </p>
<p></p>
<p>Thank you and best regards-</p>

<p>Hard to tell. The build date seems to be 9th week of 1949, which was getting close to the end of EM speaker production. It could be that the person who replaced the original was able to find one with the right voice coll value and close to the right field coil value. Magnavox built speakers for many different companies, including Hammond organs and Leslie speakers. I have two of the 31 A/H series Leslies from the 1940's, and one of them has a Magnavox 15 inch field coil speaker and the other…</p>

Magnavox built speakers for many different companies, including Hammond organs and Leslie speakers. I have two of the 31 A/H series Leslies from the 1940's, and one of them has a Magnavox 15 inch field coil speaker and the other a 15 inch Jensen field coil speaker. I have had both re-coned and the Leslies will rattle the windows. Both Leslies use quad 6L6 output tubes. This speaker could very well have come from a Leslie speaker system. Leslies are 16 ohm and most use 15 inch woofers. Some use a pair of 6550 output tubes so these would handle the power of a quad set of 2A3s. </p>

Hello Norman-<br />
I bought a frosted four color screen from Radio Daze for mine and have that installed too. Mine was missing from the escutcheon when I bought the set, but I later found it wedged down inside the cabinet. However it was damaged and badly faded, so I have kept the reproduction one in there for use. Even being frosted though, with the dial lamp glowing it is possible to see right through.<br />

Hello Norman-<br />

Good to know that the needle should be bent though; I will have to remedy that. It makes sense, and explains why the needle is essentially invisible; there is nothing to cast a shadow.<br />
What are the rivets at the bottom of the meter housing for? If nothing is missing it seems strange that they would have any reason to install those rivets that have no apparent function.<br />
Thank you and best regards-<br />
