<p>Lance: Check the back side of the outer rim of the speaker. There may be a series of numbers printed there. Jensen and other makers identified them with these numbers. The first two are the makers code, I think Jensen is #52. The next set of numbers will be a date code. Last number of the year and week of production.

I found all this information when I needed to have several Jensen and Magnavox field coil speakers re-coned for several Leslie speaker cabinets I rebuilt. There is a list of makers and their code numbers on the web. </p>

<p> </p>
<p> Thank you for the great information. I believe my speaker baffle is two to three boards glued together. I'm away from home at this time but will return this weekend and will check. I will also attempt to slide the baffle back into the cabinet to see if there are any hints of where screw holes might have been, such as pin holes in the wood, etc.. Your description of the baffle sounds exactly what I have but again I will verify this information. On the subject of the speaker, electronically I understand the difference. Was there ever a model number printed on these Jensen speakers or some type of identification? Also, you stated two field coils. From my schematic, I show a field coil, voice coil, and a antibucking coil. My voice call was open and I had it rewound. Just guessing and not knowing what I'm talking about, I would assume that the only way to tell the difference between the Jenson speakers is to perform a resistance test on the impedance matching transformer, field, and antibucking coil. </p>

<p>Norman - thanks. Good to know.</p>
<p>For the AW-15, I have seen only the casting with oval openings for the several I have had and the 4 in my possession now.</p>
<p>Presents an issue if we improve the AW-15 speaker info page in the 2nd edition of the Scott Collectors guide.</p>

<p>Thank you gentleman for the prompt replies. I will look for the 4 digit part numbers stamped on the pedestal. If I find these numbers, is there anyone who would be interested in these numbers in order to keep up with what speakers go with what radio?</p>

<p>Dave, there were three types of speakers employed in the AW-15. One was physically identical to the AW-12 Deluxe speaker, another was a cast speaker with oval openings in the basket, and the third was s stamped frame version. Visual differences cannot be relied upon for differentiating the AW-15 speaker from the AW-12 Deluxe speaker.</p>

<p>I differentiate the AW-12 and AW-15 speakers by the basket casting. You have the AW-12 speaker.</p>
<p>And different 4 diget part numbers stamped on the pedestal.</p>
<p>Two field coils. One is in the B+ circuit. The other is in the negative Bias circuit for the output tubes.</p>
<p>The field coils are wound side by side on a common tubular form.</p>

<p>For most Scott cabinets, the Tauscher sound board if used was hidden behind the speaker cloth. But the Regent cabinet of 1940-41 did display the Tauscher sound board. And some custom installations might display the sound board instead of speaker cloth.</p>

<p>The Tauscher sound board can be handy on the work bench to protect the speaker cone and improve the bass response a bit.

<p>Agree - the Tauscher sound board is best a display curiosity and not used over the speaker.</p>
<p>Look closely at your speaker baffle - it is two or three boards (Spruce?) glued up. Not plywood.</p>
<p>Those 4 large round Forstner bit holes near the corners are for attaching the speaker board to the cabinet.</p>
<p>Look closely. There is a hole drilled in the <span style="text-decoration: underline;">side</span> of each Forstner bit hole.</p>
<p>Wood screws (1" or 1 1/4" unsure of length)…</p>

<p>Wood screws (1" or 1 1/4" unsure of length) fit those holes in <span style="text-decoration: underline;">side</span> of each forester bit hole. The screws are driven sideways into the cabinet sides. Today, we might use pocket screw technology.</p>
<p>My 3 tube AW-15 amp is like your AW-12 amp - just sits with no flange to secure it. There is a Scott photo showing the amp setting beside or on top of the cabinet for conveniently using earphones. That earphone jack is two position. Inserted partway, both the speaker and earphone function. Fully inserted, the speaker goes quiet and the earphone alone functions.</p>
<p>FYI - Your AW-12 and my AW-15 amps are different and not interchangeable. Yours uses an 80 and two 45's. My AW-15 uses a 5Z3 and pair of 2A3's. And the output transformers in the speaker pedestal are different, as are the speakers and field coils. There are two field coils in both auditorium pedestal speakers (by Jensen) built specifically to meet Scott specs. </p>

<p>The Scott-Tausher sound board was not even invented during the entire run of Napier Consolette cabinets. Furthermore, although it did defeat the beam effect of a curvalinear cone, it also defeated sound quality. Remove it and hang it on the wall.</p>
