Its been a while since I’ve updated the site, so a quick update on what I’ve been up to.
The fan mods are still going strong. I haven’t had any problems so far with them. While I would strongly recommend any Ampro owner consider doing this, I also would caution that every unit may be different and you should measure before and after to satisfy yourself that the change is safe.
As for stability, its better now. I still have to sit down and do a full mechanical alignment since I know that the focus is a little off on one side, and the projector isn’t perfectly square.. but no one but myself can actually tell — for all of my guests, the picture is pretty amazing.
I’ve picked up the parts I need to try out Guy Kuo’s solar cell gray scale, and I have plans to borrow my friends ocilloscope and check the tube voltages to see that I’ve got fairly good linearity (I think this is off right now). So I have lots of plans..
BUT, currently I’m working on finishing the basement — which includes building a theater. I may post some updates on that progress here, but that’s what I’ve been up to lately.
