GE Mic preamp

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

Discrete opamp

I immediately went to work on a couple of the boards. Here is an opamp with the pins installed.
