First , let me say that the amp IS working now. Just a lower than expected power.
As mentioned before the only point where dc voltages don't align with the results in the video is between D3 and D5. See data below.
Okay, I have gone through the DC voltage measurements in the NA5Y video again and recorded the results.
Setup:
Control voltage 5v - confirmed and working.(redlight)
no input RF from QCX
Amp on 50Ohm dummy load
?
DCV Data:
? ? ? ? ? ? ? ? ?RX? ? ?TX
V+? (supply)? ? ?12.75 12.74
R5 Pin 1 0 4.97
r15 Lside 0 4.90
l10 12.72 0.1
r13 rside 0 12.7
D1 cathode (rside)12.7 0.08
D1 Anode (lside)0 .79
Point F .06 9.3 (between D3 and D5. This is way lower than NA5Y got. his was at 70v)
D3 anode .75 .04
D5 anode .75 .05
Q3 Gate 6.92 0.046
R12 gate side 6.92 0.04
?
Summary: Everything measured near exactly as NA5Y EXCEPT Point F which was significantly lower in my amp.
