Alignment and Test Part III failed

John Wiener
Hi.

Any and all help is greatly appreciated.

Here's what I get when first powering up for Alignment and Test III:

Current drawn is .26   a bit high?

Adjusting L1 and L2 for 40M and max is only 0.3 watts

When pressing "Tune" an initial Hi current reading shows
momentarily

In Troubleshooting:

R67/R68 and R66/R69 are all correct, D9 is correct

Reset relays per instructions (removing control board, etc.)

Checked count of windings on T1 - T4 and resoldered...solder joints  
look clean

R50 is not open.

I request some help with checking DC voltages in the transmitter  
area.  Also with signal tracing.
(This is new for me.)

Again,
Thanks!

John
