I have two G07's here I'm going to be rebuilding over the next hour. One is dead and one works. The dead one had the small fuse blown and a big spark when I discharged the filter cap.

Typically, the original G07 flyback has a label with a green stripe on it. It has been well-established that this flyback should be replaced during a rebuild regardless of whether it is currently working. My dead chassis has this flyback and it will be replaced.

However, my working chassis has a flyback with a different label. It looks all original, and the solder below confirms that the flyback has never been removed.

So, will this flyback also need to be replaced? I know it's normally standard when dealing with an original, but that always has the green stripe. If this is from a different manufacturer, then it may not need to be treated the same. Would rather not waste a new flyback if I don't have to.

Here are the pics:

The clean one has an original too. Who knows how long it will last. It could blow up tomorrow or it could last several years.

yeah, that's what I figured. I'll save it as an emergency flyback should I need one fast or for testing, but since I'm being paid for the replacement, I might as well use it and sleep better...
 
mod, did you put that second board in the wash? i clean all of mine and never get them looking that good.

Nope. Came out of the cab that way. Cab is in excellent condition (although converted to Jr Pac).

Every once in a while I come across a cab that was HUO or only on location for a very short time, and the chassis looks almost new. Had a HUO cocktail awhile back with a perfect G07 in it. The chassis looked like it just came from the factory.,,,
