Ken:
Why don't you remove ALL the tubes and fire up the transmitter again? If you still get a fuse blowing, assume your power supply or some other component is the culprit. Work your way up by putting in some of the lower value tubes up until the modulator, driver, and final tubes. Much easier to do it that way than "easter-egging". Let us know how it goes. Cal, N6KYR.

Well I thought I had the problem solved. but the fuse still blows.
I removed and parasitic suppressor and plate cap supply to the 6146's
resistors in L11, and L12 read 1.29 K ohms and .919 K ohms,(I removed the
resistors
from inside the coils to measure)
C31 the ceramic transmitting cap' reads 1.657 nF
Is there anything out of line on the above values? After this I am going to
check the VHF suppressors.
