i've just been looking in the 8444/8443 deck, it has the usual disintegrated Play gear cog, do i need to find the exact gear cog or have any of you ever found a different one out of something else ? i know the cogs on the 8734 have to be the right ones especially the tower gear, but wondering if the 8444/84443 can use something else, it only looked like a standard gear. By the way, i'm going to need gears for D8614, D8534, 8444, D8734 (both decks) just got to work my wallet to buy them all lol, i will do one day because i like philips and i think they are worth saving, also, how are they to work on ? are they a nightmare ? TIA
