    Marantz Pm 493 amp issue - power cycles on/off - repeat

    Hi guys, I picked up a Marantz PM493 system for free out of the classifieds today. The owner upgraded and was simply giving it away for free along with the matching CD, Tuner and double tape deck along with the original manuals and remote. When I arrived (after about a 55min drive) he tells me...

    Upgrading Vintage Marantz 1030 Power Supply to Zener Transistor

    Hi, First time poster. I've started cleaning up and recapping a Marantz 1030 as a summer project. It's going well. However, one of the things I'd like to do - due to its relative ease - is upgrade the power supply to a better level of regulation. To do this I'm going to replace the resistor to...

    Amp suggestions for totem rainmakers

    Recently picked up a pair of totem rainmakers for a pretty good deal but not sure what would be my best approach with powering them. They are 4 ohm and 87 dB. I am able to purchase a Ps audio 5.0 preamp at the moment. Then was thinking of using a power amp as well. Any body who currently has a...

    More (Emotiva) power for the rear channels?

    Good Morning all, Just toying with an idea and I figured I would throw this at the wall and see if it sticks. Currently driving Ohm model H on the front channel (8/6 ohm @ 20-100W) and Stacked Ohm C2's in parallel on the rear channels (Each 8/6 @ 20-120W) I believe. All are upgraded from Ohm...

    Realistic LAB-430 - Dead - Power Supply?

    First of all I can't find a repair / service manual anywhere for this thing. But it's similar to a beaten and broken LAB-450 parts unit I have, so I can scavenge parts from that if I have to, I think. The problem is that it's totally dead. Looking at the power source, I'm getting a good...

    Marantz 140 Power amp temporarily used with 1070 as pre/Power consumption

    Hi guys, I've spotted a nice Marantz 140 power amp that I still didn't receive but the problem is that I have no preamp yet to use with it. Also, the 140 does not have a power knob, so using the (un)switched outlet of another amp seems perfect. I have a 1070 amp (also a 2235B but the 1070 is...
