all the 5F1 champ around me have Oxford 8EV speakers and they seemed to have Jensen P8T as well. found one from CTS which sounds like the stock Oxford. they are 4 ohm impedance and DCR is mostly 3.2 ohm
I’m not sure with new and doped speakers but old, broken in and sometimes brittle speakers sound way better with edge doping in every aspect to me. it’s like a having a good preamp tube in vintage tweed amps
it’s an Oxford from ’59 Champ along with one from 62’s. the cone went yellow and I guess it was in a place with carbon monoxide gas around. both has doped in the end
and 60’s Ceramic speaker from Oxford. and another one from CTS. this CTS is not Fender stock but sounds pretty much like the stock speakers.
a friend took these C-arm Xray image intensifier films for me. as you can see, they are
PIO black beauty .022uf 400v x2
Mylar black beauty .022uf 400v
and, PIO bulbe bee .022 uf 400v
from the left to right

I started this build on my personal blogspot blog. then I moved whole the articles on slowbean. I might want to arrange them into one single thread later.
it’s my yokomo Hotdog4 built from YR4 kit with some Works bits, along with Yokomo Esprit stock motor. I’m working on the new shock towers.
MX4 rear CVD bones fits perfect for ’91 through ’93 Works. Hotdog4 has the same arms. and you guys can see the result. the length is same with post ’94 yz10 rear cvd bones.
I’ve been using this 239 bulb after the factory GE #47 bulb went dead. 239 is same 6.3V and the bayonet base is identical to #47. mine came from Westinghouse as I remember. and found more from Tung-sol, Sylvania, Chicago Miniature, and more
239 rated 2.268 watt while 47 is 0.945 watt according to this web page. I’m wondering if I can go with this bulb. but didn’t have an issue yet
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
I see two of ACY41 germanium transistors on the board.
Grabbed this off ebay for a great price. two hundred something in USD. it sounds great and quite different than my Bum fuzz and old Sola Sound fuzz pedal a friend has.
but, it has an issue. it rattles on high level. I’m sending back this back to British Pedal Company.
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
