tommypiper said:Dany, great project. But for this project, what about availability of the BV08 transformers? Now that Oliver is passed away and his partners are trying to catch up? The future may be a bit uncertain about the transformers... ???
Also, on the AMI site it mentions the BV8R as the one to use for the EF800 tube, but your pictures are showing the BV08. Can we use either transformer?
Are they available anywhere right now?
I don't want to use the high nickel Cinemag, but if there are other alternatives let me know, thanks.

If it didn't I was planning to make a modification that would allow me to adjust it, but again, I don't know specifically how I would do that.

Got my D-EF47 going finally!! Sounds amazing, gotta thank dany for putting up with my endless stupid questions and general dumbness!!!!
A while ago I have made 4 of my own U47 based on the Oliver schematics and this one sounds so much better.
Much more gain and precision in the sound.
This is the best sounding U47 circuit I've heard.
Just need to finish the nickel plating and I will post up some finished pictures.
