Is it possible to connect a pilotuner (601) to a 40-180 ?
Is the screw on the back of the chassis (says Phono) for tuning in an RP-1/2/3 wireless record player or is it for an antenna wire ? It also has a ground screw next to it ...there is no phono jack (rca) on the back of my pilotuner ..It has 1 thr 7 screws for antenna connections .
iv searched the net and found a ton of info on the tuner but nothing that covers my problem ...Most articles assume you have a phono jack on the back of your radio chassis ...
Howard, I don't have an answer to your question. But if your chassis has a phono screw(s) on it. It's not a 40-180 chassis. Probably a 40-508 or 509. Does the chassis also have a huge power transformer?
The literature for the Pilot FM tuner describes many ways to connect it. Rather than make a hole(s) in the Philco chasss fro an RCA jack, I would conect a shielded cable to the chassis and bring it out some convenient place, terminating it with a female RCA jack.
Also, watch out for AC sparks when the Pilot tuner is conencted to the radio chassis, unless both have three wire cords witht he chassis grounded in both.

there is only 1 screw and it sets in a hole and says phono /tv above that hole is another hole with narrow screw for tuning .
(i turned it while it was on and it tuned other stations on the low end of the dail) ...from some info i found here i think its for something like the rp-1 wireless record player . player ..
i have all the documentation for it form several sources and it covers all options except mine..it has no phono jack or phono screws ..(to actually hook up to)just what i think now must be for tuning .
the manual says if you have none of these options you need to have a qualified person to install it.
Well i just found this and i must say im confused ....
The Underwriters Laboratories will not permit us to include in our FM PILTOTUNER service booklet any instructions to the layman concerning the connection of the tuner to a radio receiver without phono or phono outlet, since this type of installation requires wiring directly into the circuit of the radio receiver. Therefore, we are sending you these instructions separately in this form for the use of your radio service technician.
INSTALLATION PROCEDURE
Attach center wire and outside shield wire of PILOTUNER connector cable to terminals #7 and #6 respectively of the PILOTUNER, following instructions in Par. III of service booklet.
Modify the radio receiver circuit as follows: (See diagram below)
Unsolder the wire attached to the ungrounded side of the volume control, and attach center wire of PILOTUNER connector cable to this spot. The outside shielded wire of the radio receiver. The disconnected lead from the volume control should be soldered to the center wire of a second connector cable, and through it connected to terminal #5 of the PILOTUNER. The shielded wire of this second cable should also be soldered to chassis. The radio receiver will then operate normally on standard broadcast (AM), whenever the ON-OFF switch of the FM PILOTUNER is in the OFF position.

Can someone translate this ...i can follow it up to "Unsolder the wire attached to the ungrounded side of the volume control, and attach center wire of PILOTUNER connector cable to this spot.
But beyond that im lost .
The pilot tuner is designed to be very convenient. What you are doing when you connect it that way is routing the signals from the radio to the Pilot tuner. When the Pilot tuner is off, then signal just goes back to the radio, and it operates normally. When the Pilot is on, the signal from the radio stops at the Pilot, and the signal from the Pilot goes into the radio and through its audio amplifier circuits and out the radio's speaker(s).
The Pilot can also be connected to the phonograph input, or can be connected between the phonograph and the phonograph input.

Philco made the RP-1 and 2 wireless record players to be used on any radio. Their own sets that year, probably did suggest that you could dedicate a push button (PB) to the phonograph. It made the RP players more convenient that way. The screw mentioned above was to set the PB frequency for the player.
Note that Philco either did build a prewar TV receiver, or planned one and never put it into market. In those years, TV sets had no audio amplifier built into them, and depended on the owner using his radio for the TV sound. Philco's TV sets had an oscillator in them, modulated by the TV audio. The radio was set up to tune a PB to receive the TV sound, just as from the wireless record player.
RCA's sets had an audio cable, and connected into a radio's phono jack.
