Hi guys,
I have completed the RF board up to the point where I must do the stage
II tests.
With a DMM on the left end of R30 and adjusting L30, the voltage remains
stubbornly at 8.00 volts.
I have checked the board and T5. I removed T5 and rewound it, but no
joy. I read all the past emails on the topic that I could find in my
archive and concluded that perhaps if the voltage were too low, add a
turn or two to T5 primary (red winding). If the voltage were too hiigh,
remove a primary turn. This latter I have done, but no joy.
Could anyone please suggest where I might go from here? (Apart from the
nearest lake, that is.)
Thanks in advance.
