[Boatanchors] Millen modulator...

[John Saxon]

I hope this isn't a dumb question...
I have a very nice Millen 90800 transmitter (6L6-807), use it a lot.  I also came into a very nice Millen 80311 modulator - PP 6146s, intended to mate with the Millen 90801 (5763-6146) transmitter.
Question:  Could I use the modulator with the 807 transmitter?  The modulator instructions have a section on using the modulator with another transmitter.  They indicate that is okay if the loading on the transmitter is about 4800 ohm:  600volts @ 125ma, is the example given in the manual.  The 807 loads a bit different, with the power supply I have it loads to about 500v@  80 ma, about 6250.
Could the 90831 modulator work with my 807 transmitter?
Thanks & 73,JohnK5ENQ
