I would start by writing down the filter settings (ie. the frequencies). 
After you have those down, follow the manual and do the alignment steps in 
sequence.

There are some alternatives for aligning the filters and L34 given the 
items you mention. There is an alternative to aligning C22 on the control 
board using an external receiver and WWV on 20MHz. If you have an external 
frequency counter, that can also help fine tune the setting C22. Alignment 
of the bandpass filters can be done using transmit mode with the K2 feeding 
a dummy load with a needle-based watt meter in the line. The external watt 
meter allows you to more easily see smaller changes in output power than 
that seen by the LED's of the K2.
