Package from Bulgaria just arrived with my project pc boards for the holidays…
A germanium transistor preamp and its power supply in the back.
An OA10 discrete opamp, 6-transistor diamond buffer, and a Fet Bloak in the foreground – all with 2520-style layouts.
Anyone else have plans for projects during the holidays?
regards, Jack


I immediately went to work on a couple of the boards. Here is an opamp with the pins installed.
Nice! Where did you got those Opamp boards? I want some!
1- they look interesting!
