help with TV Altec 614 cabinet plans?

Hi Guys,

Sorry to bug but I am building a pair of the Altec 614 TV front cabs like this original set. I can not seem to find a detail plan of the cab? I can sort out most of it just need a few dimensions if thats ok?

1. width of the TV front frame. size from outside edge to inside edge that makes the TV?
2. size of radius of the inside corners of the TV from?
3. Port size opening on baffel?
4. does the front TV use 3/4" Plywood like the rest of the cabinet?

Thanks so much if you could help out.

Cheers

Tony
