sorry how can i tell ? the seriel number is in the 900  working on the year .all black silver air feet and motor red trim on tonearm board . It looks like a ribbed platter with a very thick rubber pad.sorry i have only seen pics
it,s not a 4 or 5 from what i can tell on the tops of the feet it has open holes.I,ve heard some bad thinds about the air feet. sorry thats all i got i have a pic but it wont post :(
The Classic platter is silver in color with smooth sides. If it doesn’t have it, get the platter and install it on the table....very easy mod. The table is an excellent performer. Is it in good working order? The feet can always be replaced. Any isssues and you have VPI support (excellent)
