<p>Agree with Kent.</p>
<p>The Sixteen amp has 4 tubes - a pair of 6V6 output tubes and a pair of 5V4 rectifiers.</p>
<p>FYI - The tube sockets for almost every Scott model has the tube numbers imbossed on the sockets. Look closely.</p>

<p>The amp with the 4 6L6 tubes is an extra Philly amp. The other amp (with 2 6J5 tubes and 2 6L6 tubes) is a Phantom amp.</p>

<p>The Philly with the 15 in pedestal is fine, but then you do not need the crossover. The crossover should go with the FM Phantom in that case, along with the bullet tweeters. </p>
<p>Otherwise all good pairings. That extra power supply is for a Phantom, so is the speaker. There might have been a standard Phantom tuner at one point....</p>

<p>My observation of the speakers:</p>

<p>My observation of the speakers:</p>
<p>Starting 1940, crossovers are part of an extra cost optional high-fidelity speaker set, in lieu of the standard single 38 ohm speaker for the Philharmonic or Phantom models - be they FM models or the standard models.</p>
<p>The two crossovers you have are electrically the same. The larger crossover with the two larger round top coils (inductors) is the early version. All speakers used with the outboard crossover are 8 ohm. Crossover information is in Riders vol 14 (and 15). The outboard crossover includes the output transformer for all the speakers in the set, so, the main speaker will lack its own output transformer.</p>
<p>As Kent said, the 15 inch pedestal speaker is for the Philharmonic. It should have a 2 pin socket for optional tweeter pair. Any tweeters with permanent magnet (no field coil) AND higher ohm voice coils of the order of 16 ohms each are run in series with a 2 MFD cap as a crossover and connect with a "Y" cable directly to a Philharmonic pedestal speaker socket. Don't see you have these tweeters, however.</p>
<p>That large 15 inch flange mount speaker may be part of the optional hi-fi speaker set for the Laureate - if it is coaxial style with a single center mount tweeter. I note it appears to lack its own output transformer and has the kind of 5 pin plug to fit one of those crossovers. Would use the same outboard crossover you picture. In contrast, the standard single Laureate speaker may be 12 inch or 15 inch with an output transformer and 38 ohm voice coil</p>
<p>Tweeter pairs that go with the outboard crossovers will have small 2 pin plugs and 8 ohm voice coils (measure about 6 ohms resistance).</p>
<p>The two 12 inch speakers each with "high fidelity" tags and small 5 pin plugs would go with a crossovers and should have 8 ohm voice coils and field coil. And they lack their own output transformer.</p>
<p>The 12 inch pedestal speaker, as Kent said, is for the AW-15 (1934-35) and has the output transformer inside the pedestal. No tweeters for this speaker. That speaker has 2 field coils - for B+ and another for bias of the 2A3 output tubes. It is special Jensen with Scott decal.</p>
<p>*</p>
<p>Your Philharmonic is the FM version of 1940-41 and total of 33 tubes, including the 6 tube Power supply. The standard Philharmonic (BC and SW, but no FM) has a total of 30 tubes including the same 6 tube power supply. The FM version deleted the volume expander feature the AM model has.</p>
<p>I believe Radio Daze has the repo FM Philharmonic dial you need.</p>
<p>All Philharmonic power supplies use FOUR 6L6's and a pair of rectifiers (5Z3's until mid 1940, then 5U4's).</p>
<p>Phantom power supplies use a pair of 6J5 drivers, TWO output tubes (earlier 6V6's and later 6L6's) and two rectifiers (earlier 5V4's and later 5U4's). FM Phantoms (2 magic eyes) use the power supply with a TWO 6L6's.</p>

<p>Over all - it appears with all those tweeters, you are short a crossover. (which I may be able to supply).</p>
<p>Each crossover should have an extra plug with no cable (wired as a jumper) intended for use if an auxiliary/remote speaker is desired.</p>
<p>Good luck.</p>
<p>After you have some receivers paired with amp and speaker(s), start a new thread with photos for feedback.</p>
