I’ve been playing lately with the 6P15P. Also I have developed several spice models of these Russian clones <\/a>which I will be publishing shortly when I get the time to do the proper write up.<\/p>\n

I use Dmitry’s Paint_kit tool a lot. It’s very good and accurate once you learn how to use it. It’s not easy to match triodes first time as many variables are in play. After working with Derk Reefman on the pentode models, I noticed a slight divergence on his triode models. Derk suggested that the best was to use the triode-strapped pentode for this. Here is a simple comparison between Dmitry’s model and Derk’s:<\/p>\n

Here is the comparison of the two Spice models:<\/p>\n

\"6P15P<\/a> They do match very well. There is a slight missalignment at very low current (cut-off) region or saturation region (e.g. anode current above 100mA. These are operating areas where you will never use the 6P15P so no problems. I can conclude that both models are very accurate and you could use Derk’s pentode triode strapped in Spice without any issues.<\/p>\n
