NOAD Fender 1980s Superchamp

Bendyha - are you saying the original speaker you removed is the one on the right and is a Pyle?

This is the speaker in my recently acquired SC.



With the only numbers stamped on the cone.

 

You can always tell a Pyle speaker by those 4 little indents in the middle of the magnet assembly. Is that the Pyle 10" that Derek Trucks likes?. If so, he likes them because they are inefficient and tame his Super Reverb and Super 6 amps a bit.

Zombiwoof, no, this OEM Pyle that came in the Super Champs are not the Trucks speakers. Those are, as I understand it, the MH 20 and MH40 Pyles. I have one Trucks Pyle....and I have run it on a Super Champ. Very odd speaker, ime and imho. IN the clean mode, I find it to be a decent speaker....not inefficient, good low end, sparkle. However, when I pulled the Mid boost out, the speaker took on a lightly different character in that it seemed to have lost some efficiency...it 'stepped back' just a bit. That is an odd way of describing a speaker, but that is what it was like. then, when I pulled the Lead mode pot, it REALLY stepped back. It lost a great deal of presence/volume/whatever it was losing. Maybe it compresses a great deal???? At any rate, there is too much of a difference between the modes for it to be a usable speaker for me.
in comparison, the Emi ALK 1028 and the EVI in a Super Champ both yield equal volumes in all three modes due to amp compression in the gainier modes. Great speakers...in a great amp, imho.
Perhaps Trucks was attracted to these Pyle's just fro that reason. They can make a BF circuit compress and be smoother...at the cost of volume, ime. That drastic compression does yield a smooth distortion....which might be good for slide. However, I did not like the difference in the volume level that came with the gain changes. IF one were running an amp in one mode with proper settings for the sound one wanted, perhaps it is a decent speaker.

 

Yeah, Trucks likes the low efficiency Pyle in those loud Super Reverbs and Super Six amps he uses because they get his sound at less-than deafening levels. Weber makes the DT10 speaker that is a copy of the Pyle he likes, at first it was only made for and sold by Lord Valve's NBS Electronics, LV was Trucks' amp tech at the time. Later, LV allowed Weber to sell it on their site.

I peeled the SN sticker off to confirm no indents. Anyone know what speaker this is?

 

Ime, the codes are under that blue label. Sometimes one can carefully lift the label to read the codes without seriously damaging the label. Razor blades are handy. Is there a grey label on the side of the magnet?

 

Looks like there might be a bit of code stamp showing on the side there:

 

No label at all around the magnet. I will leave the blue Fender label as is.

Edit: I’ve plugged the amp into a Eminence 12” Red Coat Governor in a mojotone tweed cabinet as well as the OEM 12” Black Shadow speaker in my Mesa Boogie Studio Series amp (circa 1985) - mixed results, nothing earth shattering. The Governor was warmer, boomier, and seemed louder than the 10” SC. The Black Shadow was thin and unimmpressive. I’m back to using the 10” in the SC and like it.

Just wondering what that speaker is.

 

Mesa put the Black Shadow label on a variety of speakers....so there’s to add to confusion about speakers, right? and.....sometimes a camera shot can be taken too close....or maybe your camera is a ‘big’ picture and we are only see8ng part of it. If so, one can reduce the ‘size’.

Oops...my bad...Bendyha gave us that close up.

 

Can anyone advise how I can confirm if my Super Champ is an export version that has the transformer with the voltage selector switch? I need to convert from 120v to 240v.

Thanks

Edit -schematic added

 

we would need to see the PT in the amp to know the answer. If your PT has seven leads on the primary side, then you have the export PT.

 

Finally took the chassis out. Here are pics.

Was looking to confirm if the transformer had the voltage selector switch. The last pic I posted below pretty much answers that question.

So, follow on question.....Has anyone used a power step up transformer with these amps? Is that a bad approach? Any components at risk? Thank you super champ Gurus!










Following pic is not my amp. Found this in a different thread on tdpri posted by ScottJPatrick. It is obviously an export model given the voltage selector switch.

 

What is the wall voltage in Canada? My search says it is 120vac?? Are you moving?

 

Wally, thanks for the reply.

I did indeed move and brought the SC with me hoping I could have it wired for 240v. It’s not a permanent relocation, so any mods will eventually be reversed.

Co-worker here loaned me a step up transformer. But, if it puts anything at risk on the SC (ie 6C10), then maybe buying a new amp (SC X2) rated for 240v that I can sell later, might be best.

Cheers

 

So you are no longer in Canada? Pardon my confusion. As long as the step down transformer is providing 120VAC and has the ability to handle the current draw of that Super Champ, I figure it is good to go. A multimeter is your friend. As for the 6C10, it’s rarity does not in anyway put it in more jeopardy than the other tubes. Have you bought your spare 6C10 yet...or two of them??? I have never needed to replace either one of mine...original tubes from the early ‘80’s. I do have spares, though, because I likes my SC’s!!!!
As for a new SCX2, I would not consider that as a second amp....ymmv, but it is not a Super Champ other than in name.
Enjoy the Super Champ. Imho and 8me, your amp would benefit from a speaker change. The Pyle in your amp is ime an inarticulate speaker. The other OEM ‘budget’ speaker that came in those maps was an Eminence. It is a thin and harsh sounding speaker. eminence Legend ALK1028 speakers are great for these little amps, imho.

 

Presume you mean a step down transformer? Where are you based these days? I still have the original 120v transformer in my Gibson Falcon amp but have a small step down transformer on the inside of the cab, doubt if you could manage that with the Super Champ

 

It’s a step up and a step down transformer. It does both and weighs about the same as the SC! Correct to your point, I’ll be stepping down the voltage.

thanks for the reply.

 

No longer in Canada and I do have a spare 6C10. I think the amp still has original (Fender branded) tubes. Have not yet changed the speaker, but based on your comment, that’s where I should put my money.

thanks for the comments. Gives me confidence to give the step down! transformer a go.

cheers!
