Building 3BP1 tube NBTV Anderson monitor II
Posted: Sat Sep 17, 2016 9:45 pm
G'day all.
I am reading Harry Dalek's thread on his 3BP1 Anderson monitor as I so happen to have a 3BP1 tube myself and I intend to follow suit and build my own 3BP1. The difference with mine is I intend it to display not just 32 line NBTV but also standard 625 line video and possibly SSTV as well, I want it to be multistandard. Anyhow I have already made a start on my project and have been communicating with Harry who has been helping me plus I have been reading over his thread which Steve Anderson has been helping him extensively with his monitor.
So far for my project I have done the following:
Built the AC power supply unit which is also multipurpose for other projects
Built the Dual +/-12V power supply
Built the high voltage circuit that supplies about +340V and -1340V
Got an ex monitor amp enclosure for the tube which I cut a hole in the back for the tube to fit in.
I will elaborate on the above in the next few posts along with pics.
