Here it is!
One JBL K140 is like new, another one doesn't look good and had to have dust cap replaced (I can't reach aluminium one unfortunately), but works well at least. It's birch plywood (as mentioned in Conrad's plans) instead of pine used in original cabs, so it's probably more midrangey than original ones. It's great, has plentiful and natural low-end; to be honest I expected rather boosted, thunderous low-end but it's still nice and very controllable.
Another cab is vintage Ampeg with CTS drivers.
BTW I used Fender/Sunn tolex avaiable to order at Fender distributor stores (it look the same but it's a bit softer than original in my amps) and Fender black/white/silver aged grill cloth, which looks nice but it's more yellowish than 40 yars old nicotine smoked Sceptre.
