Just pretend you’re listening to the radio, they always play recordings fast for various reasons.So I got the 1249 all cleaned up and running. Using an rpm meter revealed it was running fast, but only a few rpm over 34 rpm Lowest it would go is 36 rpm, not matter what I tried. Not good when lp ‘s run at 33 1/3 rpm.
Turns out when someone swapped to the 860 motor (in an attempt to cure the double speed issue) they must have sourced it from Europe. European models got the 860 motor instead of the 840. Later in the run, the 860 motor became standard on NA models and was the warranty repair fix for double speed 840’s.
Now, an 860 isn't a problem, as the 860 will run on 50 hz (ie: Europe) or 60 hz (NA). While the motor will run on 50 or 60 hz, it runs faster on 60hz. So Dual put a different size pulley on the NA market ones. Use the motor with the Europe pulley and the platter runs too fast.
Sourced a NOS North American market pulley, popped it on and rpm's are tickety boo now.
Oh, I have a DENON DP62L.
I paid $500 for this in the early 2000s, it’s worth more than my entire vintage YAMAHA MX series system right now.
