Here's a pair vintage US Signal Corps mic/phono movie projector preamplifiers, licensed by Western Electric for B&H.
Tubes include: 2x 12AX7, 3x 12AU7, and 1x 6X4 rectifier.
Tested and works great. Previous owner updated input/output connectors nothing else was changed parts are identical including original UTC transformers.
Condition looks great, very clean.
