Since I put this webpage up in '04 I've received quite a number of emails from appreciative AP-D30 owners who were able to speed up their turntable thanks to the info posted within. So thanks to the people who've got in touch.
During 2004 I bought a turntable from someone who found it at a garage sale for $10, which was great seeing as my old Teac
hifi unit has been dead for many years. I carried it home and thought all was well, until I went to play a record at 45rpm.
I hadn't noticed that I'd been playing 33rpm records on the 45 setting. Over the years it had lost some speed.
Not being willing to pay $28 for a service manual, I took it apart to see if there were any adjustable components inside.
Upon taking it apart I found there were 5 variable resistors. It didn't take too long to find out the top 2 are responsible
for the playing speeds. Changing the others didn't seem to do much at all (feel free to get in contact if you know
what their purpose is).
As pictured above you can see the two resistors. Turning them anti-clockwise increases the speed. I had to turn
both of them all the way, so if it slows down again I'm not sure what I can do with it.
Anyway, my turntable now works as it should.
