You will likely damage the high frequencies because the cartridge can possibly track the record. You're increasing the frequency range by over two octaves and also increasing the velocity by more than a factor of two. Even if the cartridge could track the record - which it most certainly can't - the RIAA equalization is all wrong.

Subject: [ARSCLIST] Transferring LPs at 78 RPM
If I transfer a vinyl LP at 78 RPM then slow it down to proper speed do I lose anything?
