MXR-130 new purchase

[billeng 2]

Okay, I just put the lid on my fully functional MXR-900 when I had the chance to get an MXR-130 with a noisy balance control for $40. All seems well after some deoxid. Can anyone point me to the owners manual? I already downloaded the service manual. Does this thing have an IR receiver for a remote?

Deoxit fixes noisy pots most of the time.  There are a lot of post on this receiver packed with lots of useful information.  There you will find most of the common problems associated with this great receiver.  If you have specific questions please ask.  As you can see from my signature line I like the MXR-130.  In addition to my garage and shop I have another set up at my new home construction site.  There I can really crank it.

This receiver does not have a remote controller.

I have used dioxid for years. Good stuff. I also had to clean the molex connectors. Many were intermittent.

 

When I first powered up the unit, I believe I heard distortion between 60 hz and about 3,000 hz. It got better. That makes me thing that I need to recap this unit. I am guessing the power supply caps were reforming. I have larger caps both in capacitance and voltage in my parts box.

 

What do you think?

Edit: I found one more problem. The radio goes silent with a screwed up display when warm. I will replace the trip pot. I am skeptical that the trim pot is the problem, since cooling the CPU with freeze mist (I have a little left) causes the radio to pop back into service. If I have to buy another CPU, so be it.

The MXR-130 seems to work fine now. It has now had the relays and caps replaced plus the trim cap on the CPU board. I was unable to resist temptation. I bought a GSA-700 to go with it. I have enough speaker to outfit the rear channels.

 

In case I need it, any suggestion on where to find an ADCOM service manual? I downloaded the owners manual. I will probably recap the ADCOM.

P.S. I tried cleaning records with wood glue this weekend. To my surprise, it works. I would estimate the noise floor on a clean thrift store 45 was lowered 2 dB.
