Fender Super Reverb schematic can't find

[nosaj]

Hey there just got a Fender Super Reverb with a SS rectifier, It is a Blackface panel, there was never a tube rectifier in it. I seem to be having problems finding a scchematic for it. All I found was a premier guitar article about it and jeff Bober from Budda amps said to email him for it . But it's an invalid email.
Amp sound pretty awesome.

Any help would be appreciated.

Thanks,
Nosaj

Is there a model/chassis number on the tube chart?

No the top half is missing. Any other place it might be located? I have not opened it yet. You want pics?

Ok i found some in the SchematicHeaven folder. Unlike the other PDF's it was listed
cbs_70w_mstrvol_pullsw_super-pro-bmstr_rev .
All the other schematics were listed by the amp name.

There is also a very similar one with the same title except 45w where this one has 70w in the title.
edit: never mind, the 45w version has the tube rectifier.

Here's the pics. Had to loosen Speaker board to get chassis out. This thing reeked of cigarettes which I hate the smell.
When I got it to my shed it was overpowering. Someone had left a can of Ozium in my truck when they borrowed it. I sprayed the speaker screen smell was almost gone.
But anyway heres the pics

Teagle and Sprung don't even offer a model number for that amp. They describe it pretty well though. Master volume, but without the Randall pull boost switch. Probably the last model SR after the return to black faceplates. I'll guess 1982. Which was the last year of the SR before the reissue came out later. Some of the schems for Fender amps of that era were sort of combination schems. That is, there was a four power tube schem but I've never seen a two power tube schem. Or, there was a schem for two amps that shared circuitry and the schem was only labeled "100W reverb" or something. I tried to narrow it down using the premier Fender book and I couldn't come up with a schem specific to your amp with a *oogle search.

Maybe Jazz P Bass can find one (no pressure ) He always seems to come through when I come up dry.

Hey Chuck,

Pretty sure by the time the UL models came along, fender only made six "models": Champ, Princeton, Deluxe, Bassmans (10, 70. 135), 70W Amp w. Reverb, & 135W Amp w. Reverb. The 70W would cover the 2x6L6 reverb models and the 135W all the rest. The differences in the amps were off to the right, where there were just a bunch of different speaker wiring configurations, listed by model name. But gone were the AC568/AB1072/etc model numbers. This trend started a little earlier on in the 70s, basically when the varieties of Twin Reverbs started coming out - Super Six, Quad Reverb, Dual Showman Reverb, Twin Reverb, etc. But by the late 70s, it was pretty much set...

The correct one is the "70W Reverb Amp" I think it's called... so the Super Reverb in question could also be any 2x6L6 amp of the time. I'm not evennsire what was left by then... Pro Reverb I think was it.

Occasionally, someone will post asking "what circuit is a Bassman 50 - AC568, AC371, or...?" And the answer is "Bassman 50." Which there are two schems of. Then the Bassman 70 showed up. So there isn't one of those letter-number models for every Fender amp. The last one of those I remember seeing would date to 1972.

That's just the sort of schematic ID confusion I was eluding to. Though you've clarified more of how it was very well. I'm sure the amp is a late '81 or an '82. The HOF book describes it perfectly right down to the last circuit addition being the line out on the back. But no model number given.

EDIT: Probably this schem. Whomever wrote the dates on there (it wasn't Fender) is just off by a little. Pretty sure this is it.

[Justin Thomas]

That oughta be it... what is this HOF book of which you speak? Seems I must procure it. I love me some Fenders!

Nevermind. "History Of Fender."

Justin

[Chuck H]

I probably should have made the "O" lower case.?. (HoF)

[Justin Thomas]

Wouldn't have helped... I read it as Hall of Fame!

...Probably this schem...

Agreed and it is interesting to note that they used 16 Ohm speakers in that version Super Reverb. They are wired in parallel producing a 4 Ohm total load. When using that 70 W Master Volume chassis for projects with other speaker loads one needs to be aware of the output jack switching arrangement and that the OT secondary is 4 Ohms total with a 2 Ohm tap.
Cheers,

I want to make a correction on the book. It's actually called "Fender Amps" and then below that "The First Fifty Years" and it's by two guys named Teagle and Sprung. Is this the same book you have, Justin? The Marshall book DOES say "history of" above the title. This book actually doesn't. Good book to have. Much faster reference than the information super pile,.. Uh, highway.

[Justin Thomas]

I <had> both of those, and the Ampeg one. But they all rotted from my hands from use and abuse. But I pretty much memorized the Fender one, and I take notes on just about every old Fender I see.

And concerning the speaker changes Tom mentioned, to use 16ohm speakers wired for 4ohm load makes it one less bulky and expensive OT type to keep on the parts shelf... Just a couple short years after this particular Super was made, all Fender USA production ceased and the company was sold. They were definitely trying to meet price points and keep inventory uniform by this point. My theory, anyway. As far as assuming it's a 2ohm load like a "normal" Super Reverb, well, wouldn't one check the back panel for a spec? I always do... I also learned to check the OT for correct part number, after I played my Bassman with a wrong load for years, because it has a Twin Reverb OT in it...
