Hi,
I am planning to make a NBTV display using mirror drum. "Basic NBTV Techniques" booklet that I have mentioned that a few designs were published in NBTVA newsletter (Vol 4/1, Vol 5/1, Vol 3/4 and Vol 8/1). It may have been reprinted in other club publications as well. If someone has access to this newsletters or other design information for Mirror Drums, I will appreciate any help!
Thanks and 73,
Sergei KD6CJI
