Fender Eyelet Board - AB763 Deluxe Reverb
« on: January 03, 2022, 10:14:21 am »
I created a parts list for a Fender AB763 AB763 Deluxe Reverb
This parts list for the Fender eyelet board layout

I jotted down notes as I was using the layout diagram to create the parts list
The layout diagram image I scribbled on is shown below



Here's the link to the Fender Eyelet Board page

Here's the link to the layout diagram

Notes:
If your power transformer does not have a center tap for the filaments, use two 100 ohm 1/2 watt resistors at the lamp assembly

Deluxe reverb does not have bright switches. If you want Bright switches you will need
2 x Bright switches and 2 x 120p capacitors - I stock both of these items

The 2200 ohm resistor on the 12AT7 reverb driver tube is a 3 watt

The 2 x 470 ohm screen grid resistors on the power tubes are 3 watt

The 25uf/50v bias capacitor is a 47uf/100v capacitor

The power cord, strain relief and cord clamp are on the parts list

The AC receptacle and .047 death cap have been removed

the 25uf/25v cathode caps are 22uf/50v caps on the parts list

I included 4 x RCA plugs and 6 feet of RG175 cable to make reverb cables

I included 2 x 1 ohm resistors so you can bias the power tubes

The Deluxe Reverb has 16/475v filter caps but other AB763 reverb amp may use 20uf and 100uf filter caps

Note that the AB763 reverb amps are several different models
All of these amps are the AB763 Reverb circuit
Deluxe reverb, Vibrolux reverb, Bandmaster reverb, Pro reverb, Super reverb, Twin reverb and Dual Showman Reverb

Some parts may be different model to model, but they in the same exact spot
For example:
A twin reverb may have a .022 in the same spot as a .047 on another AB763 reverb amp
The Deluxe Reverb has 16/475v filter caps but other AB763 reverb amp may use 20uf and 100uf filter caps

Use the layout diagram for the amp you are building

You can use my parts list to create your own parts list
