Got one NKT275 Need suggestion on 2nd position transistor

[Plaidesaurus]

Got one NKT275. Need suggestions on 2nd position transistor. Want to put it in a Sunflower. I also have an AC188 and a CV7003 / OC44. Any suggestions on looking for other germaniums? Tough to find any these days but... Also, any suggestions on a different build for this than the Sunflower?

I’d focus less on part numbers and more on leakage/gain. Germanium transistor part numbers are only useful insofar as they can serve as a proxy for leakage/gain, and to a lesser extent noise/bandwidth. Have you measured the leakage and gain for the transistors that you have?

I have not. I don't have a tester for germaniums. I know that GEOFEX (I think that was the page ???) had a technique for using a MM but haven't looked at it yet. I can always drop them in and see what happens. Thanks for the info
