a close friend gave me his NOS or like new silver p12r speaker for my tweed deluxe 5d3 a few months ago. then I got me a P12N which I like for the last 15 years.
but, I couldn’t help myself to search the original p12r with the bell. I mean p12r from the same era with the same color.
I dropped by his place a couple of days ago. he showed me this p12r pulled out of his 5C3 a while ago. it was the present for me and my 5d3. I ordered a speaker cone looked like the original even before I knew he had this. and I like the black switchcraft 1/4 plug which I’ve been after.
I have emailed to dozens of electric part suppliers and messaged to ebay sellers for
and I noticed most of them are counterfeit. this seller looked legit with the picture of NOS Siemens relay. but it didn’t go well.
and it’s the the relays I got from this seller
The original Siemens, Tyco, TE connectivity relays have molded bottom with thick and strong lead pins. and, you can buy this counterfeit relay on alibaba.com or aliexpress.com for less $1 each
I’m talking to these two sellers for the original part. and one of them are running this web site
I do trust this guy and made a purchase from his ebay store
also this seller has the original relay. but it’s V23084-C2002-A403
the only difference between A303 and A403 is the contact material. and C2002 is sensitive type works with less current as far as I know. I’ll try them both and will update
another seller sent me this picture. and it’s exactly the relay I’m after. you can see the pattern on the bottom but even many of the counterfeit have the patterns as well. but please see the pins carefully all the soldering pins are thick and look strong enough.
I’m ordering a pair from this seller who sent me the picture
it took a couple of months to figure out which is the original and finally found these 2 sellers which I trust on ebay.
I’ll update when they arrive
and please someone advice me if V23084-C2001-A303 can be replaced with
V23084-C2002-A403, or V23084-C2001-A403

We take good old O2 for granted. People are always going on about how early Earth was “perfect” for life. A perfect hell maybe. No ozone layer, no oxygen, extreme heat, an abundance of highly corrosive chemicals in the atmosphere including sulfur and methane.
Much like found on Titan the largest of the moons of Jupiter today. It was a literal red sky hell. With all of that methane and sulfur, it must have smelled like a frat house on chili and hard boiled egg night. So, the Earth was devoid of oxygen in the beginning but as I said there was a metric butt-load of methane and sulfur in the oceans.
So, little single-celled organisms developed that lived on methane and sulfur. After a while, the sulfur level dropped and the methane level did as well. No one is sure why. There still was little oxygen. So some more little critters evolved which produced oxygen called “cyanobacteria”.
It took a billion years for these critters to terraform our planet for the evolution of animals and more complex plants. To this day all plants incorporate these ancient cyanobacteria into their cells in structures known as a “cyanoplasts”. You see life itself changed the planet to support life.
This is what life does.

MR-4BX series has been produced for only a couple of years. the first version came at ’06 and replaced with B-Max4 which was different from previous yoke buggies at ’08.
MR-4BX series is like the last blood of traditional Yokomo to me. and I see the same blood on Jconcepts BJ4.
I have managed to get a nicely used Worlds edition last month. and took some pics with my factory edition. they both came at ’07.
the differences between them are main chassis, F/R shock towers, top deck(s), steering, rear bulkhead, and a few misc parts
MR-4BX Worlds came with a new camber mount which allows only the longest upper rod setup. also the steering is different than previous 2 versions
this new camber mount can be installed on older versions as well
the steerings are quite different. I hope I can feel the difference while I’m running this Worlds edition. but, didn’t have a chance so far.
this steering was introduced with MX-4. prototype MX-4 still had older servo saver. and the first time I saw this was in MX-4 kit.
but the difference is the angle. this steering system on MR-4BX is tilted for better handling.
MR-4BX Worlds came with this 1 piece chassis with 2 extra holes for new steering system. please ignore the stainless screws on the Factory chassis. I’d go back to the black steel screws.
the top deck, now it covers the rear belt. and new camber mount is here
Factory edition had 2 piece top deck like the original version. but the rear piece was improved that older one has clearance problem with the belt
there were a few guys tried this before Worlds edition came. the shocks were moved to the back end of the car.
also they put a camber mount like the front end
the original and Factory edition had same suspension geometry. the shocks can be moved to the back end with this stock mount plus a few tricks
the new aluminum part which holds the the shock tower is changed along with new bulkhead and camber mount
