    Looking for a remote for a “receiver 2000”. PM me if anyone has a working  one to sell. Thanks

      Point well taken. Thanks for the heads up.

      Hey Joe. Just another heads up. The remotes for the receiver are pretty much like a gain control on the volume buttons. You have to still use the volume knob to control the sound level and then the remote will add or subtract so many decibels. It won't go from min. to max. I usually put electrical tape over the remote sensor while I work on them because my shop has florescence bulbs and it will make the receiver go crazy like Robert R said. 

       

      Good luck finding a remote. I am out of them.

      Thank you as well Rob. This is great info as well. I think perhaps I’ll pass on the remote. Not to mention there may be problems with that circuitry I’d have to deal with as well. I use to own a 2000 back in the 80’s. Totally forgot about that was how it was controlled. I’m also thankful for comment for refreshing the memory 😱

    I’m curious to see how the 2000 will compete against a couple DIY amps I built. The 2000 has been recapped with that large electrolytics and small ones on the main amp along with all the electrolytic on the ps board. Going to connect up this weekend and compare.

    Can anyone tell me, is there a way to calibrate the LED power meters on a MRX-130 or Receiver 2000? Is there a procedure I’m missing? Thank you guys in advance.

    1. Rob

      Rob

      Hey Joe. I was listening to my 150 the other day and noticed that my power meter lights were uneven and when I pushed the button in a little they would even out. So I sprayed the push button and everything works good now. I haven’t seen any calibration steps although there may be one.

      Great idea, thank you Rob

    Anyone done speaker terminal upgrades on MXR-2000? Got pix? 

    1. Joe C

      Joe C

      Or MXR-130

  5. Joe C

    MXR-130- I have an MXR-130 I’ve been trying to bring back operational and it looks like the last issue I’m having is when the FM is on and I press the asymmetrical noise reduction engage switch the, the FM goes extremely faint in the background and is totally distorted. The 4 hot resistors have been changed. I also noticed diodes D73-D76 are very hot. I’ve read about the hot resistors but don’t remember ever seeing anything about the diodes running hot. Any thoughts? Should I just replace the noise reduction board?

      What did you end up doing to get your bias voltages fixed?

    2. Joe C

      Joe C

      @Rob, it was a bad chip (IC-801) on the FEQ-508 board dragging down the +\-16vdc rails. I replaced the board but it had an issue with the switching chip IC802. I swapped out the 801’s and it’s off to the races.  
       

      On a roll, found the trouble with the noise reduction board as well. Shorted filter cap either C111 or C112 was draggy down the +/-12 feeding the board. I removed both of them and it fired up. Have new ones in order.

    Can anyone offer some information, is there a reason signal wires are twisted onto board stakes vs being soldered.

      Joe C

      Thanks Rob. I’m not having an issue there, it’s in the board in general and I was going to change it out but it looks like it may be easier to remove the entire stake and re-solder vs pulling the front panel and everything associated with it to unsolder the grays. The other thought was to untwist those connections and solder them back to the new board.

    3. Rob

      Rob

      I have had times where trying to wrap the wire back in place like factory but the wires break. So most of the time I remove the stake and clip the wire to get fresh length and solder it to the board. 

    4. RobertR

      RobertR

      Yeah  other Rob, that's how I do it.  Just be sure the stake tins decently...

    Anybody know if denatured alcohol can be used to clean smoke film from circuit boards and internal parts? Thanks

    1. RobertR

      RobertR

      I've done that a few times, with no ill effects on the equipment. Q-tips and alcohol, and the tips turn an ugly brownish yellow.

       

      Too bad the fool who did the smoking can't get the same relief for his/her lungs...

    Does anybody have a speaker selector knob for a MXR130 they would like to sell. Hit me up if so. Thanks

    1. Rob

      Rob

      If you cant find one Les @Circuits & Concepts has knobs.  But they are not the same as the originals. They are aluminum and have a set screw.

      Found one on eBay. Thanks

    Hi guys, I had a couple pictures of my bias millivolts and where I took those readings. I can’t figure out how to upload the pics from my photos to the site. Can someone assist this possibly technology challenged soul lol? Thank you in advance.

       Ok, that may explain it. Sounds like I need to be on a computer. On the app for iPhone it says insert image from url which that’s where I was lost.

      @Joe C You need to reach the rank of Novice. You're still an Inbound. I'll fix that.

      Thank you because my laptop is acting stupid the last week.
