Lomo germanium mic/line preamps + transformers

[bayanist]

For sale Lomo germanium mic preamp card including original input microphone step up transformer 1:3.
This preamps were a part of Lomo 4ch powered mono mixer. Preamp itself contain 3 germanium transistors. It can be used as mic preamp with step up transformers or preamp for line level signals.
This quite interesting schematics, small amount of current flows to the base of the first transistor through the transformer's secondary winding. Approximately 2 microamps. It is enough to open transistor but not enough to magnetize transformer core. Honestly, this preamp sound great. Overall gain with step up transformer approx. 38-40dB.
One card and one transformer including shipping 55€.
2 sets including shipping 95€.
Have 8 pcs for sale.
Will ship worldwide.
Let me know if you have any questions.
