Question re: inductance spec for LL1692A interstage

Hi there - question probably for Kevin C.

The data sheet for the interstage LL1692A, configured as push-pull 1.75+1.75:2+2 has a single primary inductance figure - 210H (Alt M).

My question is around where this inductance is measured across. Is that the total figure for the anode of one valve to the anode of the other valve - in other words from signal+ to signal- (2 lots of 105H).

Or is it measured from signal to centre-tap - so that it would be 420H from signal+ to signal- (2 lots of 210H)?

Thanks.
