EL34 SE with Lundahl LL1664

I'm becoming interested in building the above amp, as designed by Claus Byrith, which specifies a LL1664/80mA output transformer. When I look up the spec of the transformer it appears to a configurable design coping with PP as well as SE but no mention of '80mA'. Is there only one '1664 or does it have to be ordered with a particular configuration? Any guidance would be most welcome, thanks.

PS: I've tried communicating with Lundahl in the past who refer me to their UK contact but they are mostly into pro audio.
 
Looking at data sheets from their website they have 50ma and 100ma versions for SE. 80mA may be a special order one.

Some years ago I was contracting and had a VAT no and they were fast and responsive with ordering. Do you have a friend who is a contractor who has a vat No and ask him to order. Failing that it may have to be via the UK distributor or USA or Europe.
 
Thank you for your response. In the meantime I found EU pricing for the ones you mentioned, and I don't think I want to pay that sort of money, given that special order ones are unlikely to be cheaper! Perhaps I will go RH34, using UK made transformers.
