I’ve found this amp on reverb for a friend. he was in search of a Deluxe Reverb for a while then I came across this on a month ago.
I wanted to get him one with the original components and the speaker. it had an ugly red speaker when it came to me. and we were lucky to find the original Jensen C12Q with a like-new cone. the cones are the characters more than the magnet to me.
the speaker came from ’66 fender amp. it’s period correct and sounds great after my speaker tech re-glue the voice coil and damper. there was a play between the frame and the magnet. he fixed it of course. I love vintage C12Q as much as vintage Jensen P12Q and P12N
Data mining is not just the art of extracting new information; In fact, it is about identifying new patterns from data that you’ve already collected. Here are 10 best examples of data mining methods and techniques:
1. Cluster analysis to identify target groups
2. Regression analysis to bring on marketing forecasts
3. Classification analysis to spot on spams and more
4. Anomaly detection to identify abnormalities
5. Intrusion detection for system security
6. Rule learning to recognize links between data
7. Decision trees analysis to improve on project risk management
8. Neural network application for automated learning
9. Induction rule to prefigure data-based analysis
10. Data warehousing

I just tried 9V battery trick for 50’s Fender Champ 5F1 and Deluxe 5D3. and the speaker wiring turned out being reversed. both of them still have the factory wiring.
And, both of them move backward (to the magnets) when they wired 9V + to the white wire, and – pole to the black wire.
They mostly say there is no absolute speaker phase unless they are in the same cabinet. at the same time, many people say the speaker cones move forward when they hooked up in the right direction with 9V battery.
Fortunately, 9V battery didn’t kill my 8″ Champ speaker, nor 12″ Deluxe speaker. but I’ve read some cases this trick killed their speakers.
I’m not sure with 50’s and 60’s Jensen speaker’s correct phase. but, I started to believe Fender hooked them up this way. I’ve seen only 2 cases. and will update if I come across any Jensen speaker with different phase.
while I’m working on a tweed champ 5f1 replica with 10″ speaker, I recall they say the output transformers affect the tone.
and, I noticed I never saw the back side of champ chassis before. it’s where I start finding a vintage OT for my project
they are my recent build with some vintage components like Philips caps made in Holland and Roederstein caps made in W. Germany.
one of cabinets is 18″ wide version like the early 5E3. Fender changed the width to 20″ right after some of the transition models. even there were wide panel 5E3 at ’55.

the voicing of stock 8″ speaker is quite different to 50’s Oxford 8EV. I guess this stock speaker came from Oxford as well but I could be wrong.
I replaced the stock 25uf 25v power tube cathode bypass cap to 47uf.
it came with stock Amperex buggle boy which is still alive and kicking and GE 6v6gt. only the rectifier tube has replaced at some point.
stock speaker is on the right side.
I’m running this small version of Buggy Champ – Rough Rider for years. yes, it’s small and cannot run on the bumpy tracks.
and I watched it’s not bad on the the rally circuit where I’m running my old RC10 and 834B runners.
this tamtech champ came with the plastic spring dampers. buggy champ runs like tamiya grasshopper with the stock shocks. actually it runs better than grasshopper.
google found me Losi Mini-T shocks weeks or months ago. an I’m running with the shocks. losi shocks turned this tiny champ into a racer.

One of the most interesting things about DNA is that we have discovered, in humans, the 3% of the code which builds our physical bodies also has encoded within the bodies of all of our ancestors. We can switch on these old systems (in animals of course since this would be highly unethical to do to human beings) and give a chicken teeth or scales. We are not just us. We are all the physical forms in our lineage.
Now, that accounts for 3% of our storage. What of the other 97%? It is memories. Now the skeptic will go “yeah right Mr. Science”. Hear me out here though. Why is it so hard to accept memories encoded into the helix? In fact all “instinct” is encoded memory. What beach to lay your eggs by the light of the full moon if you are a tortoise. Where to migrate if you are a starling or a monarch butterfly. Sharks even have maps of the magnetic markers on the seafloor. None of this is learned. It is there at birth.
There is a very good evolutionary reason for this. Rapid adaptation. We have a repository of past experiences so we do not have to reinvent the wheel every time our environment changes. Human beings have noted this for at least as long as we have records and this has given rise to theories of reincarnation which appeared in nearly every civilization on Earth. Science has resisted this because it sounds too “supernatural” in the same way they resisted the “Big Bang” because it sounded too much like creation. Yet, it is anything but supernatural. It is entirely natural and the only explanation which makes any sense.
