The relays on the speaker terminal board SP-508 are in need of replacement, no doubt, along with a plethora of electrolytic caps, plus R635 needs to be 3.3KΩ 1W. Spend the time to check for shorted or open caps! Fix the main amp board MA-508A first, then the smaller boards. Leave the main tuner board TIM-510A and Noise Reduction board CNR-527D for last. Give the two switches for TAPE functions on FEQ-508A a good shot of DeoxIt.

Will Bernard, Freelance Subversives was released on May 1, 2020. "Will Bernard’s new recording is titled Freelance Subversives; the title itself is the best description of his method, his mindset, and his storied career. His journey began in Berkley California, itself a hotbed of both freelancers and subversives. Listening in to underground radio as a young man he picked up on the greats - first in rock and roll with The Beatles, Led Zeppelin, Dr. John, The Rolling Stones - and then the typically Bay Area sounds of The Grateful Dead, Santana, Tower Of Power, and more.

Hi All, I just acquired a somewhat broken MXR-130. I had no idea there was so much info on fixing these receivers! I've already ordered some refurbish kits on Ebay, plus deoxit etc. I am a little concerned though that I may have screwed something up; after I took off the covers, blew the dust out, etc I though I wanted to run some of the basic sm alignment procedures to better understand it's current condition. The first one I ran, per the sm, was to clip onto the D626 diode and chassis with my voltmeter and see if it's at 61.1v. It was at ~42v, so I adjusted the SVR60

Welcome to the group. I can see exactly what your problem was and yes, you made a terrible mistake - blowing the dust out is guaranteed to make it all fail in bizarre and spectacular ways - the magic dust is what makes it all work! Obviously I can't offer any good assistance in helping you get that receiver going, but as you've seen, there are lots of folks here who do know there way around the circuits and are happy to offer good help and guidance. Personally, I admire anyone willing to dive in there and have a go at things. Good for you. I'm sure it will get sorted

Welcome @Pooklord, that looks like a super project. Can't wait to see some pictures of your results!

Greetings @Pooklord ! Looks like you are well on your way!!!

Welcome! If you want to eliminate the hot resistors all together here is an option available from a trusted eBay seller CircuitsAndConcepts. Les is also a member here though not very active anymore. I have used this regulator in both of my MXR-130 recievers. A bit pricey for a repair and flip unit but well worth it for personal equipment.

Thanks for the kind words, Brian--I should have been more careful with the magic dust. lol

Welcome. I have had an MXR for 33 years. Those resistors on top of the noise reduction board are always hot. Unless it’s off. 😄
