More Germanium Diodes

More Russian Diodes

Got a few more Russian diodes from eBay. There is very little documentation available for these. They are popular with retro audio electronics tinkerers. For the purposes of a scanning switch matrix just about any kind of diode will work. I purchased these just for their looks.

I removed the colored bands on some in this post. The glass is brittle compared to modern 1n4148 glass diodes.

I believe these are D9K, D9J, D2D and D9B. They are all NOS Russian diodes.
