Uniden 810e Driver and Final Transistor Replacement
THIS IS UNTESTED i don't have this rig sorry
1pc 1000pF ceramic disc capacitor
1pc 33K ohm, 1/2 watt resistor
1pc 470K ohm, 1/2 watt resistor
1 Remove Final
2 Remove Driver
3 Remove L29
4 Remove L32
5 Remove C143
6 Remove C211 NOTE: Is on back of PCB @ finel 470P/UJ
7 Remove C145
8 Remove C202
9 Remove C180
10 Replace both Final and Driver with ERF-2030s. Note: ERF-2030 mounts identically to the Ones you removed
11 Add 33K ohm resistor (1/2 watt) (solder side of PCB) from ERF-2030 gate leg of Final to the end of R170 that is closest to the face of the radio
12 Add 470K ohm resistor (1/2 watt)(solder side of PCB) from ERF-2030 gate leg of Driver to the right leg of VR9 that is closest to the face of the radio
(NOTE: BOTTOM VIEW OF PCB The ERF-2030's Gate is the Right most leg and the Source is the Left most leg)
(Note: insulate the leads of the resistor from the surrounding traces using heat shrink tubing.)
13 Add 1000pF ceramic disc capacitor across C146 (solder side of PCB) NOTE: keep C146 470Pf in place..
14 Install EN-369FN at Final (solder side of PCB). Solder the positive lead (+) to the ERF-2030 gate.
Solder the negative lead (unmarked) to the ERF-2030 source.
15 Install EN-369DR at Driver (solder side of PCB). Solder the positive lead (+) to the ERF-2030 gate.
Solder the negative lead (unmarked) to the ERF-2030 source
be sure to check all work!!! and go over your Schematics and PCB Layout.
I hope this helps 617
