This it's the peculiar thing.it seems photobucket doesn't update the edit in real time even though to the originator it shows as edited inside photobucket. I suppose it is just a matter of posing the link and it will correct itself as photobucket catches up with itself.

Figure 9 I've done a few times, simples using a little neon bulb. The last one was variable output, used a EL84 as the series pass element. Control section was half ECC83 I think.
