while those booster diodes might do the trick - the design wont work on voluntary diodes - especially those labelled on figure coz the high ohmic collector load wont be enough in real life to lock the input diodes (or lock 'em fast) e.g. the inverters won't work at all or would work 10-s of times slower than the simulation does F;i yoo-hoo . . . everything may work better if you rise the feed voltage above ?? 1.85V 2.0V 2.16V or higher ?? (the dif.-amp starts working properly above-equal 9.6V . . .)

Transformer parametrisizing

since i had to rate a lot of 'em - i changed my prev. MMXIV-01-14 method - to a faster but not necessarily a better 1 the measurement schematic stays the same only the computations and what's being sampled a bit varies -- an example::

in short :: the ~AC-TEST -- returns ZL1(Ω) and Voltage transfer ratio - which are used in computing the LL2(mH) , UL2(V) AND IL2.Chk(mA) , e.c. ...

the dynamic ~AC-TEST (under the  [ Transformer Name : ] ) -- returns from UL1(V) , UL2(V) , RTEST.N(Ω) -- /!\ /!\ something IL2(mA) which are then checked against the ~AC-TEST based computed IL2.Chk(mA)

from this it seems that the TF(transformer)'s  power transfer is dependent on it's load -- see the RBRIDGE(Ω) under the DC-TEST -- //// -- so you need to adjust the LL2(mH) to match your circuit's average op.-g conditions (the previous method matched the average test range)

note::the "Characteristic String"  is described in HERE for more detail -- it's more meaningful inside the set of such for multiple TF-s -- has a comparative purpose.

MMXIV-09-08 note :: i in principle won't remove the below Bsh - the Blogger editor is (still - i guess) unpredictable (the 1-st impresion tends to stay - even more if there's no tendency to improvement throughout several . . . years ◄ such fixes a permanent attitude like below - i suggest you don't focus)

sub-note: Kuradi sita virvendus! Mõlemad - Blogger ja FF - nii koos kui eraldi -- üks kukub ära ja teine ei saa hakkama -- eriline utoopia on mingit asja siin üldse aretada kui debiilikud on töövahendeid üritanud teha (hea on kui see asi nüüd nii jääb nagu ta praegu paistab (kuradi idiootide maa - nahhui . . . persse!)) - no offence this is how i see it . . . i always wondered why people remove their blogs - i guess such may be a reason - if you try to do it (blog) too often - it eats the last of your nerves off . . .

Kõik , võimlemistund on tänaseks läbi XD (Vabakava Googli ja Tulirebasega XD XD XD &%!&&/!(&/¤#!%%/%¤ . . . Põrgu´!)
