Alamo Challenger Speaker Impedance Question

Hi,
Thanks for all the info and interesting topics...... I've been reading your posts for the last month or so. Reading all of the amp build post has got me thinking I should pull my old Alamo amp out of the closet and replace the blown speaker.

Here's where I run aground, the speaker isn't marked and researching my Alamo Model 2562 never gets me very far. As far as I can tell from the tubes, this amp is some form of a Fender Champ, 6v6gta, 12ax7, 5y3gt. The output transformer has two lugs one marked 8 and the other marked 16. The 8 inch speaker is connected to the lug marked 16. I'm guessing this means the speaker is 16 ohm? Can anyone confirm the correct speaker for this amp? Or is there a way to figure out the correct impedance value?

Thanks again,
Vince :cool:

I lieve that if you use a multimeter, you can determine the ohm rating of your speaker. Simply put the +probe on the + terminal of the speaker and the - probe on the - terminal of the speaker.

Thanks, Jaybird....... I'll give it a try. If nothing else, this will be a learning experience. What kind of amp do you prefer?

Hello my 1965 Alamo Challenger uses a 8ohm speaker 6v6 5y3 and 12ax7.

My '67 Alamo Embassy with this tube layout, 6AV6 12AX7A 6V6 5Y3GT, uses an 8 ohm speaker.
