You could do as the poster in this did and just use a generic breadboard: https://www.eevblog.com/forum/projects/5-transistor-esr-meter-design/msg4594744/#msg4594744

The zip in the download on this page has a PCB. Is that what you are looking for?

hi and thanks for replying. no the project was a 7 transistor j diddy b design. he designed two versions. one had 5 transistors with no short detect. the other 7 transistors with. he never published a thru hold pcb for the 7 transistor version.
