RE: Looks like that warped record is causing that...

I agree with Cougar that the problem is initiated by the warped record. The platter appears to be spinning with good stability. However, the arm/cartridge resonance is becoming excited by the record warps, which indicates the resonance frequency is too low. This can be resolved only by installing a different cartridge with lower compliance in order to raise the arm/cartridge resonance frequency. Silicone fluid tonearm damping would also help the situation.

I wonder if your 17D3's cantilever suspension is wearing out and becoming more compliant, which would lower the arm/cartridge resonance frequency. At any rate, the platter seems to be spinning smoothly while the warped LP is causing the tonearm to bounce and excite the arm/cartridge resonance. I have a feeling the cantilever suspension on your 17D3 might be wearing out and becoming more compliant.

Good luck,
John Elison
