I think modessitt started doing some repair work.
If your G07 is complete but not worked on, I'll trade you a rebuilt G07-CBO chassis for it for $70 shipped. This includes new flyback, hi-temp capacitors (all Nichicon brand capacitors, and all replaced). Bench tested for at /least/ 24 hours.
Yes, I do repairs on (right now) K7000's (standard res), 4600's, 4900's/5500's (standard res), G07's, 7400's, U2000's, U5000's, and 6100's - mainly because I have easy stuff for testing them. I can work on lots of other models, too - even the dreaded D9200 - if I have a tube/yoke for testing, but most people don't want to ship me an entire monitor. This list may change as I sort through everything I have.
Most of the time I can turn them in a week or two, but not always, and I give no guarantees on a timeframe. Sometimes it's very fast. Other times I end up tracking down some
bastard problem that takes a while to solve.
Regardless of the amount of time it actually takes me to fix it, for the above monitors, I charge $50 + parts + shipping. If you have already installed a flyback/cap kit/etc - then the parts may be nothing - as it could be a trace problem that you can't figure out yourself. If you already have the parts and want to send them along, that also saves you money on my end. Most of my parts prices are the same as Bob Roberts, as I get a lot of my stuff from him (but not all).
For a G07, your best bet would be to go with the $70 trade mentioned above. A G07 rebuild requires a new transformer if yours is original (even if it still works) as it will most likely fail very soon after a full cap replacement. My cost to you would be:
G07 Repair - $50
Parts - Flyback $20, Cap Kit - $5, HOT (if needed) $5, VR (if needed) $5, Fuses (if needed) $1, Horizontal Width Coil (if needed) $10
Return Shipping to you (Large Priority Mail in Lower 48) - $14
It's up to you to decide what's worth it to you...
