I need to replace the 130-150W tube in my Sinjoe 1290. The power source is an HY-DY20.

I searched the forum for "best tube" and "best tube brands" but did not get anything that really answered what I am asking.

I do a lot of cutting and some engraving.

Is the current power source (which seems to be functioning) a good option or should I consider changing it? What brand/type of tube is best to replace with and does anyone have recommendations to buy from?

Thanks - Dan
