The way you have it drawn would connect the junction of the series capacitors to an AC ground. Do the Treble controls work? Never mind that question, you're probably not ready to fire it up yet.
If that serial,number falls in the number range that sits at the end of 1963 and the beginning of 1964, I would call the amp a 1963 based on the ink stamp date on the chassis…unless that decode is in the the last week of the year, maybe. Those serial number charts are good for all of the year except that transition from the end of 9ne to the beginning of the next. The authors of the articles “Dating Fender Amps” admit to this vagueness on the cusp of the year.but the imprinted serial number is 1964
It is true that prior to the BF era Fender schematic numbers were in fact model numbers as well as dating codes for the circuit. That model correlation went away for many models when they started the BF era. There is a date code for the circuit, but many schematics share the same codes among different models…especially in the BF era.Maybe to add the actual model number would be a good idea .....
You are correct. My apologies guys that previous drawing I posted is wrong. David Barnett's in post #27 is correct.Do the red lines drawn correctly? The point where the three resistors come together in each group is the power supply node. If the red lines go to the far ends of the 220K resistors instead, this would be an RC network across the plate resistor. What's the value of the yellow ceramic caps?

And if what I've drawn is incorrect, where do those ends of the resistors go?
That number is on the cusp for BF non-verb Deluxe amps. I would date that amp to 1963 unless I found other date codes that established that it was a very early 1964.Serial number impressed into chassis is A 00658.
That's what I figured. So then it forms a second order high pass filter.
One cap is 500pF, what is the other cap?
