Disconnect PS-7 pr power supply from TR-7.

Remove TR-7 wrap-a-round cover.

Re-connect PS-7 or power supply

Locate on TR-7 and select the 10 meter band, receive mode.  The anode of CR-1501 should measure zero volts or no more that 300 millivolts.   The anode of CR-1503 should measure +10 to +11 volts DC.

Connect dummy load to TR-7

Select CW mode and advance the gain control to full output.  Key the TR-7, the anode of CR-1501 should measure +1- to +11 volts DC.    The anode of CR-1503 should measure zero to no more the 800 millivolts.

Replace diodes accordingly to achieve proper results.
