An old guy...but Noobe here. Doing my bit to keep vintage audio gear alive and real. Not a fan of Class-D...how can chopping a power supply sound like a pair of EL34s or KT66s

Currently trying to repair an Amber 3501 test set...circa 1988. Checking out whether it might be possible to improve the input section with modern semiconductors...particularly since the 2SK146 Dual JFETs are unobtainium....Thinking some members might give me some pointers.

What kind of Carver gear do you have?

If my memory serves, you can look at PartsExpress for a comparable part. I don't know/cant recall if that is a National Semiconductor, Motorola or Hitachi part. Worst case, ask chatgpt or geminiAI for a compstible replacement part.
