GB4000 + Amp for sale

Hey guys,

My friend is selling his GB4000 Rife machine plus amplifier and so I wanted to offer it to anyone on here before it is sold. He is charging about half the price it would be to buy it outright, and it is in perfect working condition. If interested, please send me a private message through my contact form and I will put you in touch with him.

    Hey! Danielle? I might be interested in the GB4000. It’s probably already sold, but any idea how old it is, etc? Flora M, Lyme 21yrs.

      Hi Flora!
      I regret to say that he did sell it yesterday, actually. If you go to the Lyme Yahoo Rife group, sometimes people post that they are selling their rife machines.
      All the best in health,

          You are selling your rife machine… why? And what did you use it for? How old is it? Is there anyone to help with how to use it, etc…

            I have a carefully used GB400 MOPA for sale. My husband bought it and used for several months but his stage 4 cancer won the race. I’d like to sell it for a reasonable amount but I’m very negotiable. Just want someone to have it that could benefit from it. He bought it from the website

            feel free to email if you are interested.

    If you are still looking… My father-in-law bought one 3 days before entering the hospital. The NEW machine has not even been un-boxed. My M-I-L is trying to sell it as my F-I-L passed a few weeks later. I’ll try to check back here in a few days and we can connect.

      Hi Kris,
      Still have a GB4000 for sale or did you sell it to Brie (bellow)?
      Please email me back, and if you want to expedite sale,
      call me -808-430-4483 after 11AM PST.
      I am in Hawaii but I would happily do shipping costs.

        Sorry folks for not jumping back on here sooner. Life has been crazy. Still have the machine and i guess I need to figure out a secure way for us to have a conversation without having my email or phone number here. I just got another email today from someone interested… So, let me see what may come of that and I’ll be sure to get back on here right after that. Thanks, and sorry again! -Kris

    Anyone have any thoughts about DIE OFF in the brain? I don’t Herx often but when I do it is CNS issues. It seems like the die-offi is in my brain? I don’t get arthritic flare ups or muscle issues anymore… but CNS issues.

    I usually wait until the evening to take fiber + activated charcoal. This goes through the digestive track and I assume clearing the track helps the body focus on clearing the die-off in the brain.

    Any thoughts?

    Thanks so much.

    Brand new machine is still for sale. My mother-in-law needs a fair offer, for this $4500 machine. Certainly not full price, but she doesn’t want to give it away.

    Hi Kris,

    Perhaps interested in your GB4000. Can you contact me at

    Given the price that was paid, I was wondering what that included, e.g., M.O.P.A and gas tube?

    Thanks, Basil.

    • Kris
      May 14, 2012 at 1:50 pm

      I guess I should be clear… The GB-4000 comes with a MOPA 90 Watt Amp. w/ Elenco F-2800 Freq. Counter. Hence the price paid.

    I am interested in your GB-4000 system. I am sorry to hear about your father in law passing before he could be helped.
    If the person asking about the die off should read this, I was really helped by using an ionic foot bath after rife treatments, didn’t experience die off at all that way,though it felt like i was going to die when I used the rife machine without the foot bath!

    I have a very lightly used GB-4000/SR-4 combo that formerly belonged to my uncle, who was able to fight off his pancreatic cancer for a good few years before passing. He was known for keeping his possessions in good condition. Please feel free to shoot me a price and we can discuss a sale. I’m willing to ship it nearly anywhere in the US.

          Hi Carol Lynn,
          I do not have a GB4000 available, but I have a MOPA with plasma tube, in perfect condition, and very lightly used.
          It is too powerful for me!
          I think I only used it twice.
          I like the low power settings on the SR4 amp.
          This equipment cost me about $2900, 3 years ago.
          I would pass it along for $1800.
          Are you interested?
