Need black/white pointer knobs for Champ 25.

[Bill Moore]

I've finally got a PT built for this old combo, and need to replace a couple of knobs. The Fender # is 002-6403-000. My friend brought me some, but they're 180 deg from what I need,(white pointer is opposite the flat on the shaft). Used is fine, thanks for looking in your odds and ends drawers. Bill

Knobs

Did you look on Watts Tube Audio? Are your pots unusual or just the knobs. The set screw is usually opposite the pointer.

These are like the red knobs, only black. They push on the shaft, and are keyed by the shaft cut out.
Some later model amps use an identical looking knob, but the key is reversed. I have some later ones, but the white pointer points down, away from the numbers.

If the pointer is pointing away from the numbers loosen the pot and rotate it so the pointer points to the numbers. Maybe some pics would help.

Thanks, but the Champ 25 is a circuit board amp,(SS pre, and 2-6L6 power), so the pots are soldered to the board. Somebody has bound to have trashed one, and saved the knobs.

I am with you Bill. They make the D-shaft knobs pointing both ways. Seems to me one of the red knob models has all the knobs on the front panel one way and there is a knob or two on the rear panel with reverse indexing.

Is that Fender part # for the ones you need? Does Fender no longer have them?

perhaps a whole new set of some other knob? There are other D-shaft knobs

[Bill Moore]

Thanks, Enzo, yes that's the discontinued # for the black knob. If I could get a couple of red knobs, I'd stick them on reverb or volume or somewhere to make it seem normal. I am missing one, and it looks like one has been chewed on?
This weekend I'm going to pull the tubes, and check voltages, and see if there is a problem that opened the primary side of the PT.
I know I've already spent more on this little amp than it's worth, but it belonged to my nephew. He left it at my house, and brought me a half stack he had traded for, and I fixed that for him. Unfortunatly, like a lot of kids, he got tangled up with drugs, and killed himself a few years back. 21 years old!
Anyway, I thought I'd make it work, just to make it work, I know it's silly.

SO is white pointer opposite flat what you need? Or is that what your friend brought that was wrong?

How about something like this? Flat towards pointer.

Looks like different amounts of shaft cutout.

Yes white is opposite the flat, the links you sent look close enough to the originals, they ought to work, I just have to measure what I need.
Found out why the PT was dead this weekend, one of the diodes in the HV circuit was shorted. (My nephew had installed a 6A fuse instead of the 1A slo-blo). I'm going to change the filter caps while I'm at it, and probably those cheesy input jacks, just in case.
Thanks for your help, Bill.

Note the two different percentage of flat area versions of otherwise same knobs.
