I used the original 2-prong AC plug and socket on the back of the radio chassis to connect AC power to the BSR 310 record changer. I had to be careful about routing the AC cord and the audio cords plus the changer ground wire to the radio chassis. The AC cord comes up the right side of the cabinet while the audio cord and ground come up the left side. All are secured with cable and twist ties to make sure nothing can get caught in moving parts including the rotating AM Loop Antenna.
I removed the plastic molded feet from the bottom of the record changer base using a hacksaw blade so that it would rest flush with the top surface of the rose colored Philco record changer base. I drilled 4 small holes in the plastic base of the BSR changer and used some #8 5/16 Hex Head screws to attach the BSR base to the Philco base. It is a great fit with the BSR resting exactly between the support/tilt-pivot brackets of the Philco changer base. After spending about 6+ hours working on all the issues I decided to stop. I will take a rest and work on this again tomorrow.
As to making up for needed gain on the changer to the audio circuits of the Philco, I will just look for a pre-assembled preamp of tube type to add in circuit if needed. I could probably add a 12AX7 preamp stage in a small Bud-box, but just don't want to go to that much trouble constructing a custom piece. It will probably come from the on-line auction site.
I will also try to get some pictures of the installation of the record changer and post them tomorrow.
