I run an ART-13 unmodified with the dynamotor for normal AM use, I use the 
lollipop mic as found with the WS19 set, tank radio, the one with the holes 
in (Microphone hand no3), the T-17 is no good and you will not get the mod. 
use in the carbon mic setting. I am interested in your 160m mod for the LF 
unit as I have both, do you have that to hand as I would like to operate top 
band using this radio. I also have a BC-610 but that is another story.
I found that in the dynamic position you have to have a small preamp to get 
full mod, if you run it right with a carbon mic and get the plate needle to 
kick upto 200 mills then the mod is 99%. I have had very good success with 
my ART-13 and get around 90 - 120w of carrier which is about right, I have 
had QSO's Stateside from the UK using this and an inverted V doublet.
I also run a couple of computer fans sucking the air OUT of the rear of the 
transmitter, keeps it happy that way, also acts as a very good room heater 
on these cold mornings hihi. Good luck and get it on the air soon.
