I was stupid enough too let someone borrow my G5700 for a while, and got it back silent. I suspect that it was hooked up too more than one pair of speakers, and driven hard enough too blow the output stage. Since then it has been stored for some years. I don't think I am able to fix this my self, and suspect after reading some posts about these receivers that not even the local tech would be able to fix it without spending a lot of time (and money) on the job, Resulting in a final bill well above what the thing are worth. A non original working unit are in my opinion better than a original non working unit, as in the last case its either too can it or try to sell it as is. (which probably would be almost the same as giving away. So my question to those who have experience with these are: Would it be possible to remove the power amp section and use the receiver as a Tuner/pre without loosing any of the functions? eventually replace the whole power amp section with a Hypex UCD/SMPS combo?
