Blue Hawaii BJT Build thread

The original design of Blue Hawaii uses 2SK170 BL grade which has the IDSS grade in the same range of LSK389B.

Double check the data sheet to confirm.

2SK170/LSK389 are JFET so using either 10K or 50K volume pot should be fine. 10K pot may be more ideal if your source can drive it.

TL; DR: I’ve wanted to build a Blue Hawaii ever since I read about it on head-wize. I finally got around building a mini BH-BJT packed into a small enclosure like a can of sardines. Many small tweaks were done in attempt to reach the measured performance of the original Blue Hawaii. The details of the journey are recorded here.

Many thanks to Dr. Kevin Gilmore for designing this legendary project. Thanks to Kerry, JimL, Joamat and many others for making it such a fun journey.
