I have an Empire 698 that seems to be running fast. I can't find one single post in the archives with anyone discussing an Empire 698 speed problem and apparently these are reputed to be ultra-reliable. I can't figure this one out. At first, I thought that I had the wrong belt. Then I purchased a new one as per the advice of Joel at The Turntable Factory and the problem is the same. I guess there is no speed adjustment on this unit. Any thoughts???
...anyone else wants a crack at figuring this out. I'm just selling it for what I paid for it. It's a really clean machine sans issues. Maybe it is just the wrong belt.....
The belt is critical and the only
one I know of that is correct
is from alexatelier.
Most of the ones that say they
are for the empire are not correct
and will make it run fast.
There is a fine speed adjustment,
the knurled knob under the belt cover, but it only makes slight adjustments, less than 1%.
Ref my post below, that's who had me send my NOS belts and I was not successful in the end. I wonder if they have gotten around to actually originating belts based on the ones I sent. That was about 6-7 years ago and they seemed to be trying to buy belts that matched mine rather than create a fresh fabrication as the belts they sent were not right.
Mr Blue Sky I hope you will report back if you do decide to try another belt.
I too have been unable to find ANY replacement belt to make my 698 run properly..and yes, the replacement belts available make mine run fast too. I know its not my TT because I have a NOS belt and this works perfectly.
One of the other replacement belt guys even had me send him my NOS belt as well as a NOS replacement that didn't work (it was a different version I think the db208??I'd have to check it...only worked at 45 speeed!) Anyway after going back and forth and wasting tons of postage, they never sent me a belt that actually came close to working but swore that their belts did work and I was the only one with a problem. I could also not tweak it satisfactorally with the speed adjustment control. The belts they sent weren't the same in texture, elasticity or thickness.
So I don't have an answer but you are not alone..I'd love to know if there is a solution.
No, the belt I have as a replacement is exactly the same as the vintage belt that was on the machine. Additionally, this is the belt that is recommended by Joel at the Turntable Factory. He gave me a source for the correct one. What speed adjustment are you talking about?
Of the three bolts supporting the motor, one has a knurled finger-nut on it - this is the fine speed adjustment; it works by moving the belt up or down on the ever-so-slightly tapered platter (I think, pretty sure I read that here before).
To clear the air,
The platter is NOT tapered, Not on the 208, 398, 498, 598, or 698.
All the EMPIRES use the PABST motors and the motor speed is very accurate.
The ONLY thing that will change motor speed is line FREQUENCY'
Line voltage will NOT affect motor speed.
Voltage recommendations for EMPIRE's is 105 to 125 volts AC.
For EMPIRE's made for 50HZ the platter area where the belt runs is machined to a smaller diameter. At 50HZ the motor runs at a slower speed and with the platter diameter smaller it brings the speed back to what is needed.
I have several NEW, old stock, original from EMPIRE, 50HZ platters.
Along with a dozen or so EMPIRE TT's of all the different models.
The speed thingy is the BELT!!!
I get my belts from Tim at turntablebasics,com
does the thumbscrew act as fine adjust for speed, and if so, how?
The thumb screw slightly changes the motor pully pitch. That is all it does.
The effect on speed is minimal!
Mostly on the 33 speed the pulley is slightly larger in the 'middle' (very slightly) of the belt path.
Turning the knurled nut it changes the pitch of the pully causing the belt to seek a slight different path. This will allow the belt to gravatate to the change in diameter.
KEEP IN MIND that this difference is MINUTE!
All 398's and 498's and early 598's were THREE speed. (33/45/78)
Later 598's and all 698's are TWO speed only. (33/45)
240V, 50Hz, and the Papst motor was marked "240V/50Hz" ( a 598 and a 698 )
All else on the Empire was interchangeable with the "North American" model, there was no change in belt size or platter size whatsoever
I have "new" ORIGINAL, from EMPIRE, the FACTORY 'conversion' KIT from EMPIRE with the platter that IS "factory" machined to a SMALLER diameter and stamped on the top "50HZ".
This kit is in 'original' EMPIRE box and with installation paperwork!
Sorry to disapoint you.
I aggree with you Grin.
One of my 698's that I purchased
new in 1980 was an export model.
In the box was a kit to change back to 60HZ. It contained a motor
pulley and an adhesive strobe disc.
The platter was stamped 50HZ but there was no difference in size,
only in the strobe disc ring that you were instructed to pry off and replace with the adhesive backed 60HZ ring.
If this inmates Empire is an export model it could still have the 50HZ pulley.
If it is not, then I maintain it
is the wrong belt.
He says it matches the belt it came with but that could have been a wrong replacement also. (Did that
belt work properly?).
The INNER platter, of course. Where the belt runs.
Me, I'm just a lawnmower, you can tell me by the way I walk....
