Found a record changer at a garage sale, but not a BOL, and much newer. Its 4 speed Philco p/n 35-1586-1 Run 3 Model C-3. No data for it on this site. Any help, need wiring info??

Hey Thomas D,
Astatic N-56 w/0.0007 radii synthetic sapphire stylus. Is it good for old 78's?

Philco tended to use Voice of Music changers. However, your P/N is not a VM number. In other instances, Philco used Webcor changers. Try contacting West-Tech http://www.west-techservices.com/index.htm good luck.

Gary,
Thanks for the input, but already been there. I resurfaced the idler wheel with an "O" ring, ($0.29 vs $20-$40) for a new one, got the cartridge electrically loaded correctly, and connected into the original wiring harness for the BOL changer and now works great. I have a minor problem with low freq. oscillations, which I think are originating at the phono amp (7C6). It almost seems that music passages near the osc. freq starts the process, and is related to the volume/tone control settings. There is a note for the -1011 version about oscillations in this tube, but haven't confirmed with the Philco experts whether it may apply to the -1008.

When I play my turntable, but not CD or tape, at high volume, I get low frequency oscillations from my 15" woofers, through the floor and the table the turntable is sitting on. Try a thick piece of foam under the turntable and see if that makes any difference. My living room floor seems to resonate at about 40 Hz.

Lewis,
Got the same effect with the changer on the bench with rubber wheels and radio setting on a wheeled platform on concrete. In both cases the changer is spring suspended w/foam damper inserts in the springs, on a custom platform. The phono amp circuit (7C6)in the -1011 is considerably different than my -1008, but also includes some modifications (Riders) to avoid oscillations. Although the cabinet/phono tray are all original materials/construction, there may be some natural resonances otherwise unadvertised. The custom mounting platform is 5/8" MDF rigidly attached to the tilt-out tray, but changer floats above. Since the 12" speaker, changer and hinged tilt out tray are all one assembly, there may well be acoustic coupling to the pickup, but it should disappear if changer is on the bench.

Lewis,
Well, maybe I was wrong about the bench tests. Anyway, a rod/lever underneath that raises the tone arm was touching a rear cabinet crossmember, and transferring cabinet vibrations directly to the tonearm/pickup. Acoustic feedback after all. I rearranged all the radio/phono I/O cables thinking it was electrical feedback via the Hi Z pickup wires and Lo Z output cables with no help. Then pulled out the phono tray and it dissappeared. Push back in and it came back. Got underneath with a flashlight and found the offending area. I did all my testing with the phono tray seated in the normal listening position, otherwise with the tray out and speaker tilted toward the floor, it sounds bad to my ears.

I dunno, but when I read your post, I got deja vu all over again. My stereo system is all components, so the turntable is sitting in a credenza with the other equipment, while the speakers are floor standing consoles. The gain has to be pretty high, and I can change the frequency by standing in different places on the hardwoood floor. I am not really worrying about this as I am burning all my favorite LP albums on to CDs, so I can play them as loud as I please. (When my wife isn't around, that is.)

Lewis,
Sitting on its foam dampened springs, it appeared to float freely. Found out later it was also touching the metal tray that mounted the original BOL changer. I'm not into music and rarely have a radio/stereo on except for testing, but just wanted it to work right. I have several hundred old LP's 45's and 78's, but it would be too costly and especially time consuming to transfer to CD for my listening pleasure or lack thereof. Maybe some day, when I quit buying radios.
Thanks for the help.
