I found some K147's and some J72's at work which are the same family as the J74/K170 just a higher current rating. I am going to attempt to use those however they are house marked so I don't know what the gain code is? is there a quick and easy way to set up a test jig to figure it out?

and what if the N and the P devices are different gain codes? would there just be asymmetrical distortion?

Hi

Is there another version of the Zen I/V Converter circuit using only 2SK170 ?

I have only the 2SK170 and I would like to use them to made the Zen I/V Converter without buying the 2SJ74

Thanx

Paul
