[R-390] R-390 (not A) transformer

[hackmohr at myfairpoint.net]

Tom,
 
With an assumed good Non-A power supply out of the radio at my bench I 
get 0.7 ohms across each of the two primary windings measured directly 
at the base of the transformer. So far I've only had it powered up with 
the audio and if chassis in place. The regulated +180VDC was good so 
I'm assuming the primaries are OK. 
 
By the way if you happen to have a spare RF slug rack and the Z219 
transformer assembly with mounting hardware I'm looking for them to get 
going again on my Non-A. Good luck with yours and keep posting as you 
work your way through it.

       Hello All,

I am working on an R-390 (not A). Could someone tell me the DC
resistance of the transformer primaries?
The radio blows the AC fuse and I am worried that it might be the
transformer. 
With the transformer disconnected, I read 1.7 Ohms between terminals 1
and 2, and 1.2 Ohms between 3, and 4.
