SQUID kit for WESTINGHOUSE AERIOLA SR. ANTIQUE RADIO

Description

Here´s a dud (open filament) brass based / tipped top, original 1920´s WD-11 tube to plug into the socket of your Aeriola Senior antique radio plus a more "modern" subminiature CK5676 tube to clip onto the tube socket terminals out of sight below the panel (see the next-to-last photo for a typical installation).
With this pair, you get the proper cosmetic appearance of the original tube plus the functionality of the hidden "helper" tube.  All the operating battery voltages and connections remain exactly the same as per the original instructions.
As the batteries originally specified for use with the Aeriola Sr. (1.5 V, #6 "ignitor" "A" and 22 1/2 V "B" batteries) are very expensive nowadays, I am including a set of much more readily available batteries which I have tested and verified to work just fine in this radio:
> A "D" cell alkaline flashlight battery + holder and gator clip leads.  As the CK5676 tube filament draws only about 100 mA, you can expect to get more than 100 hours of A battery life with "The Squid".  In fact, you can probably get even more run time if you connect a small external resistance (say 5 Ohms or so,
NOT INCLUDED
) in series with the battery holder going to the radio. In my personal experience, a brand new D cell will often give MORE power to the tube than you want (excess regeneration = squealing), even with the filament rheostat at its minimum setting.
SIDE NOTE:
Folks who plan to run a 5676 tube from an ARBE III or similar power supply will typically add a 10 Ohms or so resistor in parallel with the filament in order to raise the current draw up to the 250 mA that would have been pulled by a "real" WD-11 tube.  If you don´t have to worry about battery life, this makes the Aeriola´s filament rheostat behave closer to how it would with a WD-11.  Since one of the goals of this kit is to minimize battery (or $$$ ARBE III) cost, The Squid does not include a parallel filament resistor.
>Three 9 Volts "transistor batteries" which can be snapped together to obtain a B supply voltage of ~18.6 (2 batteries) or 29 Volts (3 batteries).  A pair of snap-in leads with gator clip ends for connection to the radio terminals are included.  Measured plate (B supply) current is less than 1 mA at 29 V, so a set of 9V batteries should last more than 200 hours.
Also included:
> Copies of the Raytheon CK5676 tube specifications and characteristic curves.
> A Velcro strip which you can use, if desired, to secure The Squid inside the case of your Aeriola.
> A pair of gator clip terminated leads to connect the D cell holder to the A battery terminals of the radio.
INSTALLATION:  Connect the RED lead to the PLATE (the fat pin on the WD-11 base).
Connect the GREEN lead to the GRID (opposite from the fat pin).
Connect the YELLOW leads to the FILAMENT (2 pins either side of the fat pin).
Connect the A and B batteries as per the factory hookup lid card (last photo).
CAUTION:  The lead wires of The Squid are very fine and delicate, their crimped / soldered joints even more so. So, be extra careful when installing.
