Default Re: Bush TV22 restoration

Well, I have some progress to report. I managed to successfully rewind both blocking oscillator and frame output transformers using a hand drill clamped in a vice. I even got the oscillator transformer back in the right way round first time (pure luck)! So I now have my first raster. An AM signal generator at 41.5MHz and 45MHz gives me tone and vision bars respectively so the RF deck seems to be working. Time to have a go at producing some video. I was intending first to try producing composite sync using an Arduino (my programming skills have so far only managed to get an LED to flash!). I also read that it might be possible to use a the video card in a PC configured using the "modeline" tool to produce 405 lines. Any advice would be appreciated.
