Thank you for your suggestion - I will look one up.

Any suggestions for improving the picture quality (especially brightness/contrast and focus)? I haven't replaced any resistors; and many of them may be out of spec. I'm sure it needs to be aligned as well. I'd like to learn to do this, but know that it requires a lot of equipment that I don't yet own.
