I am about to purchase a black face super reverb. it looks to be all
original and in near mint condition. it is a bit of a mystery because
it has a 15" JBL D130F instead of 4 10s. I've never seen one like this
but I know that fender has done some weird things in the past. What do
you think about the possible value of this amp or how rare it might be?

Tom,

I had a Vibrosonic Twin in the '70s which was basically a Twin with a 15" instead of 2 x12. Maybe your Super is a Vibro - something model. Could be legit, just semantics.

I agree with Vince. Fender's Vibroverb has circuit AA763, or AB763 driving a
JBL D130F. That's exactly the same circuit as your Super. A previous owner
may have changed the baffle for a 15 instead of the 410. It's not common but
it's not rare. It probably sounds very good. The Vibroverb is a very very
very good amp. Nice score.

Tom, Super reverb will have a 2 ohm output transformer. That will make it
different than all the other Fender Ab763 style chassis of that era. It may
have different Capacitors at the normal and Vibrato channels in the form of
.022 value instead of .047. Also, you can tell by the serial number if it
is there. Right side ..back of chassis. (
http://www.superchamp.dk/papers/dating_fender_tube_amps.htm )

The amp would be worth far more if it were in original form. That is, A 4x12
fender combo cabinet with 4x10" speakers. Mojo makes excellent cabinets for
that purpose and Ted weber sells great speakers to fill it. I just built one
from scratch. I am assuming the 15" speaker was added later or that the
Super reverb chassis was installed in a Fender Vibroverb cabinet. Is the 15"
speaker directly in the center of the amp (baffle board)? If it is, it is a
Vibroverb cabinet. If not and it is offset to one side, it is a Vibosonic
Reverb cabinet. That is a 100 watt amp and would be the same size chassis as
a Twin reverb, dual Showman Reverb, Super Six Reverb, Quad Reverb Chassis.
You Super Reverb chassis is one inch shorter in length than these and is
the same chassis size and roughly the same power as a bandmaster Reverb, a
Pro Reverb etc. All Fender amps of that era are worth more when in their
original state. Mixing and matching chassis with other combo cabs and heas
is common. And, If you like it and just want to enjoy it, by all means leave
it that way except for one thing.....Make sure that if the chassis is truly
a Super Reverb Chassis, and the combo cabinet has a 15" speaker in it, that
you output transformer is matched with it. 4 ohm transformer to 4 ohm
speaker. 8 ohm transformer to 8 ohm speaker. Here is a transformer chart
from Fender you can use to check it. There is a transformer number on the
transformer. . If it is 2 ohm Fender Super reverb transformer, don't run it
with that 15" speaker.
What also could have happened is someone could have just put a Super Reverb
faceplate on Fender Vibroverb. Then, you would have matching impedances
between speaker and chassis. Key is: Find out what transformer is in the
chassis...then check speaker impedance. They need to match.

Hope this helped and wasn't to long. My intent was to be helpful. Don

Thanks for the reply. I build amps so I know about all the stuff you
were talking about. I should have mentioned that haha. Anyway, I'm
going to check out the amp tomorrow and I will check the serial
number, the tube chart, the output transformer, etc. It is certainly a
Super Reverb cabinet. They're a few inches taller than any model that
had a factory 15" speaker so I know its a super cab. The speaker is an
orange frame D130F with the fender label on it so I would assume that
it was OEM on some fender amp. Once i get a closer look i'll be able
to tell if the baffle is original and possibly get a date code off the
speaker. He says it came from the factory that way. I'm skeptical but
I know that Fender did some weird things on occasion.
