Neve 2254 build with ba185, ba191, ba192, ba283

[SIXTYNINER]

I have no idea, I have only ever used Carnhill, Marinair & St Ives in Neve things I have built.

Best way for sure is to keep all as the original, (and +1 here about),
despite various "here & there" on the web
say that the output transformer is essential .....,
cheers.
