So I've got some time and have plucked up the courage to restore these old ladies (or have them restored by competent people  :pray:). These were top of the Philips passive speaker line up in the early 70's and seemingly pretty expensive (info says the equivalent of EUR800 in 1970).

9 drivers per 80 litre cabinet (4 x AD0160/T8, 4 x  AD5060/M8 and 1 x AD1256/W8) with a maximum power handling of 50w, a virtually flat frequency response from 25Hz up 20kHz and a db@1m somewhere in the high 90's. These can move a lot of air and play orchestral and big band genres to fantastic levels.

Drivers: all in excellent condition including the original rubber surrounds which are nearly 50 years old (pre-planned obsolescence era  ;D )

Crossovers: I really would like to have these properly restored / re-worked. I did have a stab at replacing the old caps but I'm not happy with the quality of what I've done.

Cabinets: this is the the crux of the matter. At 50 years old these are looking tired, especially the front bezel which is at a 45 degree angle and showing a number of deep chips. The front grill cloth is not removable (actually it is but I think I'll destroy it in the process) but the cloth is in good condition. This morning I removed all the drivers, crossover and fiberglass wool in preparation for the cabinetry work.

Now I need to find an expert, one option is Stolze Pianos in Pretoria (suggested by [member=18]Timber_MG[/member] ) by who could fix up the blemishes and finish in a piano lacquer (expensive). Another option would be to sand them down (remove the veneer), fix the damaged areas and paint in a high quality gloss via a local cabinet maker. I would love some input / advice from those who have done something similar.

On the crossovers, should I replace with new ones or restore these ones? Any recommendations as to who I could contact for this?
