1J24B Pentode Experimenters Board
Please see this blog post for more information:
https://audiodiwhy.blogspot.com/2021/12/1j24b-pentode-developers-board-vca-and.html
The 1J24B is a low cost, low power pentode that is popular for audio development: VCAs, filters, preamps and so on.
The board is difficult to breadboard since it's not socketed.
This developers/experimenters board brings the tube's leads to 100mil pins and makes it easy to provide 1.5V cathode power from ground to -15V using diodes and current limiting resistors
