I just receive my Fender Champ from my friend! Really good job, every components bring back to life, for an electronic tech, he did it as a God! Change de jacks, pots, wires, plugs ... the only problem I got it's my speaker's getting old and I don't know where to find a good one. I need a 8 inchs speakers with 3,2 ohms. I look around in differents electronic shop and they never got some with the wide range of a guitar amp! Did someone knows where to fin some online?

Thanks for your help!

Since my question is on my Champ again, I will continue that thread! So my amp is almost all rebuild, I have a friend who rebuild all the circuit, I'm waiting for my new speaker to arrive but there's only one thing. I need some pots for the volume, bass and treble. I need :
Bass: 250 KOhms
Treble: 250 KOhms
Volume: 1 MOhms
By the way, I discover that there's a difference between linear and logarythmic (sorry I'm not sure for that word) But the only linear one I found is really huge 'cause these's a cliping end ( I explain myself: when you turn it pass zero there's a clic and it's totaly off) But after looking in different store I never found one without the clipping option. The bad part it's they are too big to fit in. Did you know guys where to fin those pots (I already try eBay but I'm not sure I want to pay 10$ of shipping for a really small part).

Thanks for your help again! :D

maybe someone can correct me, but don't speakers that measure 3.2 ohms DC resistance generally have 4 ohms impedance?

and just to make sure i understand my terminology, resistance is to DC what impedance is to AC?

Yes DC resistance is measured with a DC meter so it's often less than the real impedance of the speaker.and the speaker actually fluctuates impedance as it gets played anyway.
You have AC voltage driving the speaker but the impedance is to make it compatible with the tube or tubes being usedto get the maximum power and tone from the amp.
The right pots for the Champ are available from Electrosonic in Toronto or if you have one in Quebec.Try a local electronics shop in your area.Make sure to get Audio pots for the volume control.The one you have is for earlier champs that had no on/off switch.Alpha is the company that makes pots for the amp.There are lots more too.

Why are you essentially replacing every component in the amp? Unless it was in a flooded basement that seems a little extreme.

That beginning wit a couple change, like the transformer and a couple of caps, after that My speaker brokes, so I order one! My friend really loves is job and he told me that he wants to try something! He take the shematics and rebuild it for is own fun! For me there's no change in the sound, and I know now if something goes wrong I just have to call him! ;)

Addicted to tubes: Thanks for the tips, it's make my search easier! But what is the difference between solid and split one? And do I need long or short shaft? Sorry guyz, I'm really bad with electronics components! Thanks again for your help! :D

T-Ron, a vintage Champ is designed around a 4-ohm speaker (measures 3.2). They are quite available. Weber seems to be a popular choice. Kendrick offered one at one time. If you can't find one locally or on CGF, perhaps go to Chapters/Indigo and pick up a copy of Vintage Guitar magazine and go through the ads. If it's a choice between a boutique specialist in the States or your local Fender dealer, pick the boutique to save time.

Yeah, I found a speaker by Gregg (geek). He is a really great guy to deal with! He's a Jensen and Weber dealer, so if you ever need something, ask him! He really know his stuff!

250k

It's a little pricy, but it's only for the item, I wanna if i'm looking on the good way! ;)

Thanks
Ti-Ron mon ami, la meilleur choix est ici:

Check out the Alpha pots, with standard 3/8" bushings, audio taper.

Lots of guitar amp stuff. Use USPS mail for delivery and order at least $50 of parts and the customs/taxes won't hurt so much.

Since I got my amp back, I can't stop playing and I think I can give you some feed back on it! My friend change every little piece in it to make me a new (old) amp with it! The only thing I keep it's the chassis the amp box the tube holder and the knobs! Every electronics piece got updated! He also put an 1/4 jack for the speaker, make it easier tu plug it and harder to broke the wires 9what I did the first week I got it)The little monster is in a really good shape now! I'm pretty sure some purist would kill me for what I did to the amp but after some caps burn my friend want to rebuild it for is fun and challenge! And for me that was really cool to saw the work in progress and now I have a really good amp! Here's some pictures of after/before! Have fun! ;)

Ti-Ron, the amp looks great (and so does that Tokai!). Did you pick that up on eBay?? I've been looking for a reasonably priced Champ or Vibro Champ but no luck so far. People are asking waaaayyy too much.

Stratin2traynor:
I bought it from a forumer, here, Old Crow. He have a lot of old gear in good condition at a fair price! I paid around 300$ for it and I put around 100$ in piece and beer! ;) It's the best amp I ever had! My first tupe so maybe I'll find some other! ;)
