WHAT AM I DOING WRONG?

[ejforwood Jerold Forwood]

Hi all,

I need help!

I have 2 SB-401's and I seem to have the same problem with both transmitters.
The first one was working but had low output, only about 40 watts.  So I started by cleaning all the relay contacts and band switches. Then I bought a complete set of new/old stock tubes and started to realign the whole thing according to the alignment procedure in the manual using my SB-301 connected as a transceiver setup.  I could not get more than .2 Volts RF at pin 2 of the 6CL6 driver as I adjusted the grid coils.  This was also the same case as I proceeded on to the wire between the pins 5 on the 6146A finals and the plate coils.  I have the 50ma bias, but I now have no output at all.  I have good high voltage, but no grid or plate current.   

I bought the second  transmitter an it is a good one.  The LMO dial works, even the hairline.  It had about 50 - 60 watts out.  So I cleaned and re-tubed and started with the realigning.  This time I used the xtal pack as a stand alone.  I have good DC voltage at the oscillator test point but low RF voltage from there on.   Now I have the same result, NO OUTPUT!

HELP!!!

Thanks and 73's,

Jerry, K0EJF
