6v6 Pushpull question

Ok, I have just completed my amp and I'm in the process of testing. The power supply called for a 5H choke of 137 Ohms, the choke I had on hand is a 5H but the resistance is only 105 Ohms. I used an Electroprint output transformer that was left over from another project. During my tests I noticed that the screen voltages on the 6v6's is higher than the plate voltage, this I put down to the winding resistance of the output transformer primaries being greater than the chokes resistance.
Need I worrying about this or will this condition change once I use the amp under load. I have not fed a signal into the amp yet.
Hope you can make sense of my question. Thanks.
