Love Novia Scotia!! Haven't been there for years
I have my Maggie's on the 4 ohm tap of my tube amp, and to me they sound great. Nominally there are a 4 ohm speaker though

Hi jrwaudio! Well anytime you can get back to Nova Scotia it is even more beautiful...

The gentleman I purchased the two tube mono blocks from told me to always keep a speaker load on it when turned on so I was worried about trying a 6 ohm load on a 4 ohm tap initially but it all worked out in the end...4 ohm taps it is! Just being over cautious lol. 

I have lived all over the world . There is no place more beautiful than
Nova Scotia or better people than Canadians or a Country better than Canada .
Americans should thank God we have such a great neighbor we tend to ignore .

8 ohm has taps have worked much better for me than 4 ohm taps when driving 6 ohm speakers-  and it wasn't even close. 
but this is just a reference point- you really need to test carefully.
