Hello to all! Maybe someone has a datasheet on CV2231 (А2266, Е2266) with curves? I would really appreciate your help!

First port of call is always tubedata.info where the datasheet was located

No curves , you will have to plot these yourself if you have the valves in your possession

Thank you very much for your answer. Oh sure. I was there first. I was offered a lot of these lamps at a low cost, so I decide whether to buy or not. I don’t have a tracer, and drawing curves by hand for a very long time.

I have never seen one of these valves in over 20 years collecting . Ask for a sample from the supplier , test it and plot the curves . There is probably a very good reason why there were a lot of these going cheap

I also never saw them in DIY schemes. But I like the data. Unfortunately, sample delivery from the UK will not be cheap. I will look for trace options. Thanks so much for the advice.

Could it be similar to a PL81?
