Dating fender champ
The tone is similar to the 5F1 but has less punch and volume due to the flawed power section.These will benefit from adding a 1K ohm 2 watt screen resistor and fixing the flaw in the power section.In the silverface era Eminence, Oxford, Utah and Rola were more often used and Jensen was phased out.Even at we struggle with keeping a correct amp and speaker model overview.Looking at the chart below we can see that there was a pretty consistent numbering scheme for the vintage tweed Fender Champs.Champion 800 (green tweed)* 01 to 1000 – 1948-49 Champion 600 5B1 (two tone) 01 to 1300 – 1948-49 1300 to 1700 – 1950 1700 to 5000 – 1951-52 5000 to 5500 – 1953 Champ 5C1, 5D1 (tweed) 5500 to 6600 – 1953 6600 to 8000 – 1954 8000 to 9999 – 1955 Champ 5E1, 5F1 (tweed) C00001 to C00800 – 1955 C00800 to C03100 – 1956 C03100 to C06000 – 1957 C06000 to C08800 – 1958 C08800 to C12500 – 1959 C12500 to C15500 – 1960 C15500 to C16800 – 1961 C17000 to C19000 – 1962 C19000 to C21000 – 1963 C21000 to C23000 – 1964 So we can see that a serial number of C 09556 is pretty close to the lower end for serial numbers for 1959 5F1 tweed Fender Champs.This rare Champ is the similar to the 5F1 Tweed Champ but has a choke in the power section rather than the Pi filter that the 5F1 has.The screen and plate voltage come off the same filter cap which is a design flaw.
On my 1959 tweed Champ amplifier, the serial number is located right in front of the fuse cap.
I've built many of these over the years and pairing them with ten or twelve inch ceramic magnet speaker really helps out. Volume NOTE: There is a flaw in all of these models.
The B voltage comes off pin 2 of the rectifier rather than pin 8. Increasing the filtering and adding a screen resistor are good things to do to improve tone as well.
I service and build Champs so I would be happy to modify one to the specs you desire or restore it to it's full glory.
There have many Champ models produced after the models I will discuss but are not considered classics so we will limit it to the vintage models produced from 1948 to 1982. Cosmetically the Champions differ from the 5C1 and the Champion 600 used a six inch speaker with the Champion 800 and 5C1 used an eight inch speaker.
