C3G preamp
 
Hi all,

I would like to try a single gain stage line preamp, with C3G tubes in triode. Anybody has a schematic available for this ?

Yes, exactly! Much thanks!:cheers:

It is certainly not the most suitable for a line stage tube. The high gain demands a rather peculiar transformer. Is the effort worth it?

Well, i am not going to use the high gain of the tube, i specifically want to have low gain . I have a lot of tubes, but these came recommended to me to work well in preamp/phono situations. So, i'll give it a try.
Pentode to triode that is, with a strong power supply rectifier of the GZ family. transformer must be around 8-10k, split 600ohm capable of handling 60mA, the above blog refers to Hashimoto or Lundahl transformers but you can have any transformer made basically. What tube would you suggest? much thanks for your input
