Samson ETM3 Paddle Morse Key Telegraph
ETM-3 Squeeze Keyer. Another key from the German makers Spacemark.
In good cosmetic condition - however currently it's not working.
I purchased it a few years back and it was then working fine.
It then"gave up the ghost".
.There is one internal fuse which is intact.
I haven't proceeded any further than that in my fault finding efforts.
Sold as seen, spares or repair.
