You could try asking here,
UK Vintage Radio Discussion Forums

There is a hifi forum for older gear on the site.

It a forum like this and is very highly moderated but friendly non the less. You have to join to see anything.

This Brochure list the crossover as:
12/18/6 dB per Octave 7 element
Crossover Point 4 kHz

I have a feeling the 93-8330 is a Wharfdale Part number

I asked the people at Falcon Acoustics and got a quick response:

"That's a batch code, not a value. It's probably a case of taking it out, turning it over and/or going to Specsavers..

PS if it's any consolation we have the same problem often, the printing can be very small!"
Looks like a common thing! I'll look into it this week, fingers crossed.

You can see everything except the 'Modern' section without joining. You need a minimum number of posts before the 'Modern' section becomes visible. This helps keep the forum for vintage enthusiasts. The old Wharfedales should qualify for the vintage audio section so this won't be a problem.

They have it!

The good people at Wharfedale scanned the original service sheet and sent it to me.

http://www.deviantpics.com/images/2012/11/30/2.jpg

So, for anyone who will someday google this, the crossover is:
1x 450 uF
1x 4.7 uF, ±10% LL
2x 6 uF.

Sofaspud had a good guess.

The biggest one will have to be electrolyte bipolar, and the others I'll change for some kind of film capacitor.

Thank you all for helping!

Good to find them helpful.

The 450uf cap can be "made" by connecting two 1000uf caps in series. Connect either plus to plus or minus to minus (it doesn't matter).
