Philips Vintage Record player AG9115

['LIVEWIRE?']

Since there are no mechanical details in the AG9115pdf manual it isn't much help, but that in Lawrence's link may do so. Somewhere I have a manual for one of the Philips Auto-changers, plus a scrap Philips deck. I'm not as familiar with Philips record decks as I am with BSR & Garrard ones, but I suspect there is, or should be, some form of Cam Gear to control the operation.

I can confirm that this document describes how the deck works. The gear is disengaged by a spring, but obviously this action has to be initiated elsewhere.

I've only got a French version of the AG1015 turntable manual which means I've no idea what the lingo is saying but so far as I can make out from the diagram the intermediate gearwheel is disengaged from the platters gear teeth towards the end of slider plate 17's return journey, angled arm 23 is mounted on slider plate 17.

Towards the end of 17's return journey, 23 makes contact with pivoted arm 19 and pushes it, thus pulling the intermediate gearwheel (which is on the other side of 19's pivot point) away from the platter's gear teeth.

EDIT: Just to add for clarity, the slider plate 17 is connected to the crank arm that's connected to the large gearwheel that's driven by the intermediate gearwheel.

Some more figuring out from the diagram.....so far as I can make out....

The right hand side of the metal tab that's bent down on pivoted arm 40 makes contact with the left hand side of the longest arm on 23, the next shortest arm on 23 being the contact point referred to in my previous post (23 contacts and pushes 19) The shortest arm on 23 is bent to a tab, it being the restraint for one end of 23's spring, the other end of the spring being restrained by the vertical pin that's fixed to slider plate 17, the pin being just to the right of 23's pivot pin, the spring exerting an anti clockwise force on 23.

From that and the previous post it can be figured out in basic terms how the intermediate gearwheel is engaged and disengaged from the platter, engagement is by the wire push rod on the controls or by the trip mechanism 93 during record run out.

Extract from the English version of the manual. Of course it's not much use without the associated drawings, but I'm not going to post these on here.

I do have the manual for this Turntable, it's 5.8MB, thus can't be uploaded here. Unfortuantely having the manual does not help.

I have put up a youtue video, WITH the intermediate gear removed, it goes where the pin with the C clip goes. The intermediate gear arm, does move in and out, of engagement with the platter, but i cant see WHAT is supposed to move the intermediate gear away from the platter.

Something must be broken off somewhere.

I made a 2nd video, with the intermediate black gear in place and turning it by hand. As you can see, there is something that should disengage the intermediate gear, but moving it away from the platter, but i cant see what is supposed to do that...

I am still suspicious about the bottom of the platter, where it looks like a CAM should exist, perhaps. Also suspicious of the black trigger arm that contacts that part of the platter. The black plastic looks broken off. These two parts are my main suspects, but as i dont have another one to compare to, well.....

Please see the close up photos of these parts.

Extract from the manual to be used in conjunction with the extract in post #25

I'm looking at the AG1015/95 turntable manual (the French version)

The sliding plate 17 has a spring loaded cranked arm 23 on it, when the cycle is started by pressing the button the rod that's connected to the button mechanism moves forward and pushes lever 40, the block that's fixed to the left hand side of that lever then engages with the platters hub, the rotating hub then pushes 40 to the right, that moves 23 (in a clockwise direction) which allows arm 19 to be pulled towards the left by the arms spring, thus engaging the intermediate gearwheel with the platter, this by way of the large gearwheel and its crank moves 17 to the right, as it moves to the right a brass roller 37 that's on it contacts and pushes on arm 24, the upstand on that arm locks 19 (thus keeping the intermediate gear engaged) while the cycle is underway.

When the cycle starts to come to its end, 24 is free to move again because brass roller 37 is no longer restraining it, 24 therefore has now no locking effect on 19 and 19 is free to move when 23 (on 17 now moving leftwards) makes contact with it. During the last part of 17's movement leftwards, 23 pushes 19 thus disengaging the intermediate gearwheel from the gear teeth on the platter.

EDIT: Post crossed.

I think you'll find that the piece of black plastic is part of the trip lever mechanism. When the run out groove is encountered at the end of the record, the trip lever moves rapidly towards the turntable hub and comes into contact with the protrusion on the hub. The trip lever is then pushed back initiating the end of record sequence.

Well Dear Friends, re-reading all your comments, and studying the whole setup again, i started to play with level 40, which does move left and right very freely. However as stated in the manual and the post here, it must also move IN and OUT after contacting the cam on the platter. THIS WAS THE NEEDED CLUE !! Thank you so much.

Level 40 was not moving in and out freely, must be the only component that did not move freely in ALL Directions. A quick spray with some isopropyl alchol and it was free in all directions. Put it back together and it works rather well, though the sound output from the cartridge is a low, as i have to turn up the volume to almost full.

Thank you all for your time to respond and hope this helps anyone else with a similiar problem.

Good to know it's fixed

BTW: If anybody has the center pin for the stacker, i would love to buy it from you as i just love watching the auto changers working..

[Phantomrose1999]

I bought 3 Spindles from Canada, hoping one of them would fit my philips turntable, but all 3x are way to fat !! It seems the philips turntable needs a rather thin shaft.. oh well, back to hunting.
