    Butchered Later Revision G-7700

    Working my way through a very butchered G-7700, it went to an absolute hack shop, to a reputable tech who unfortunately passed away before he could get to it, and now to me. So far it seems like one channel is probably ok to go but my other channel keeps smoking R51 and R53 with no outputs...

    Saving a Hitachi HT-MD03

    I found it recently and was thinking if it was even worth saving and what I needed to buy for it to work, if there even is a point in trying to do so. It also has this weird cable, cheers.
