He actually shipped it today, so should arrive soon.
The seller told me about the only 1968 item was the tube chart,
probably "RA" January 1968 if they have those two numbers in 1968.
That is why he advertised 1967/1968.
Said the tube chart has AB763.
So, from what I have been reading, it should be a Silverface with Blackface
circuitry that will not need an added Blackface modification.
Even "if" it is not a Blackface circuit, I will leave it alone, not matter.

Seller stated the speakers state "Fender" on them.
Are you thinking the "Fender" speaker's actual OEM is Jensen C12N????
That would be real cool.
And you stated that Fender only shipped Jensen C12Ns for several years
from 1967 through 1981. So, are the "Fender" labeled speakers OK?
Are they really Jensen C12N's in disguise?
Thanks again and looking forward to your response. Toppscore
Fender on some speaker models like the Jensen C12N applied Fender labels on the dome caps. This was perfectly normal. In most Fender price lists during 60s and 70s regardless of speaker model Fender identified the speakers generically as "heavy duty speaker" without identifying the brand & model. The main exception were JBL speakers which were a prominent option. It is also possible they might have listed Electro Voice (EV) speakers as an option in some price lists.


Blackface Twin Reverb introduced with AA763 circuit
A00001 to A01200 - 1964 <-- 2 x Oxford 12T6 12" speakers
A01201 to A04300 - 1965
A04301 to A07000 - 1966 <-- JBL D-120F speaker option introduced

Silverface Twin Reverb
1967-69
  • Stock factory OEM speaker configuration at Silverface Twin Reverb Amp introduction is: 2 x Jensen C12N speakers. These speakers had a Fender blue label applied on the dome cover.
  • Other OEM speaker brands replaced the Jensen C12N at later dates: Oxford 12T6 12" and Utah 12" (later became Pyle Speakers). The exact amp production years these speaker models apply to at this stage is unclear.
Confusion is created by speakers swapped out during warranty repairs to other brands and owners in early years swapping to other speaker brands. Reconing wasn't a common business until 1970s, so prior to this time period it was common to install a new speakers to replace blown ones. All these situations make it hard later to track OEM speaker factory installation time periods in Silverface Twin Reverbs.
