I bought a 1257 at a pawn shop, back in the late 90s, along with a Yamaha receiver and a pair of AR18b speakers, for my grandad to listen to his big band records in his den. Fast forward to 2011 and I inherited the lot when he passed. I setup the receiver and speakers with my SL1200 turntable, but the 1257 went on the closet. Yes, the record covers the strobe, mostly. It’s kinda stupid, but a properly working unit holds speed well, so it’s not something you should have to adjust often. I replaced the Stuerpimpel and cleaned/lubed mine, and it works great, except for a nagging hum I can’t seem to resolve. I swapped out the worn Ortofon for a new AT95EVM, with the proper adaptor, but I’m still getting a bad hum, so I’m thinking I might have a bad tonearm wire.

Could be a dirty muting circuit also (if this model has one).

@@millervintagehifi3034 I'm not sure, now that you mention it..., I'll check. Thanks.

There are capacitors in the motor control circuit you want to replace. There are re-cap kits on the internet. Make sure you get the right ones. A couple of them are designated as X2 safety capacitors so you can't use just any old thing on hand. These caps are prone to failure with age. They can cause speed problems or the motor to run backwards at startup.

Glad you mentioned that...I fixed one of these a few years back and I had to replace one of those caps.

@@millervintagehifi3034 I bought one of these a few years back. I love DUAL turntables but they develop quirks with age. Another issue they have is the lubricants turning to tar. Once serviced they are amazing. I restored 3 1219 DUALs from the early 70s and they are amazing when working properly.

I really like the 1019...if I had to run a Dual it would be my choice despite the opinion that the 1219 is probably considered a better table.

What idiots at The Goodwill Store, writing on the dust cover, and worse than that using strapping tape to hold it on the turntable. The right thing to do is tie string around it to hold it on. Strapping tape does damage to it, and the turntable.

For sure...duct tape, old school masking tape, packing tape, etc will all cause damage if left on long enough.
