Alternative platters ?

[MartinT]

His deck sounded great, 33 1/3 sounded awesome, with bass timbre to die for (#jealous) but he couldn't spin a record up a 45 rpm for love nor money

That was a problem I found with a heavy metal platter, the fact that spinning at 45rpm really pushed the circuit's compensation to the limit. I could hear the 'warble' even after I removed the Sound Hi-Fi motor dynamics mod. For my ears, platters that weigh about the same as the Technics original are best suited to the circuit (strictly, have the same rotational momentum).
