    2270 transformer testing

    Glad to hear you got it figured out. I had been following your post as I am just getting started out just as you and felt that I had a transformer issue. Just as yours, I think I have a something else other than the trans. Good job with the group troubleshooting. You are giving me hope on...

    No power on 4300

    Alright , I dig a little deeper later when I get home. So if I have good voltage to the transformer but still no power, should I swap the transformer for the one I have? And is it as simple as color matching the wires to the power supply. Thanks for your input.

    I can't say for certain at the moment. However I do believe there were more that just 2 wires. 4 is possible. When the power button is depressed the switchable outlet powers on. Just no power to anything else.

    I'm not sure if I'm understanding. What do you mean by both halves? Thanks for the suggestions

    Ok, I have a replacement transformer and should have time later tonight to swap it out. Do you guys have any pointers? I am asking because there are ten wires associated with the transformer. There are 2 orange, 2yellow, 2 green, 1 black, 1 white, 1 red, 1 blue. Obviously the wires that have...

    Well, I should be receiving the transformer this weekend. Not sure if I'll have time to get it in this weekend or not. Very glad I found the transformer when I did. Either way, I'll update this post when i get it together for anyone who is interested. Thanks for the help. Much appreciated

    I know this is a bit preemptive but I found a 4300 transformer in good working order today for $25. Last resort. Just in case....

    No power on 4300

    I had questioned the power switch myself however when the power button is depressed the switchable outlet on the rear has power. Unless there are multiple contacts in the switch? I just checked JM03 and JM04 on the phase convertor and read 0.00. Same as for the J806 and J804 on the power...

    No power on 4300

    Well, no luck. I tried connecting a speaker to the receiver to see if it was just the lights out. No relay click. No lights. No sound.

    Thanks for the response, I actually pulled an old speaker out last night to confirm that but didn't get to check it yet. Will check this afternoon. However, shouldnt I hear the relay click after initial start?

    No power on 4300

    Hey all, I am in high hopes of restoring a 4300 quad. I received this unit free but not working. It appears to be in great shape cosmetically. I plan on replacing capacitors one board at a time starting with the power supply. However, before I get involved in doing anything with this unit I...

    P800 Power supply removal

    I am just getting started with replacing the caps on my 4300. It appears that there will be a couple of wires that will be difficult to remove.I feel like I am overlooking something simple. I just thought I'd reach out to some of the experienced folks out here. I would prefer not to splice...

    Just starting out

    Hey guys, I'm just getting started here. I currently own a newer Marantz 6010 unit for a home theater setup. I also have a Pioneer PL518 turntable currently hooked up at the moment to the same system. I have been on the lookout for a vintage receiver to setup my turntable with in another room...
