I'm pretty new here... recently stumbled across my TG in the attic and have spent the last couple months obsessed with my TG childhood. ;-) (mostly been buying and playing with all the stuff I couldn't afford as a kid!)
Reading your previous posts it sounds like you need cap replacements done on both units?
I've never done it for other folks, but have been repairing my own systems for a while now. (modded my first TG-16 when I was 14, added slo-mo on a turbo pad and added A/V jacks to my console... before there was internet access and all this awesome documentation... ;-)
Lemme know if you can't find anyone else, I'd be willing to give it a go.
