Replacing a transformer

This was done really quickly on my way out the door this morning. I'll replace both r14 and 15 tonight and measure again.

So far, everything in the bias supply, seems to be in order. I wouldn't worry about the R14, R15, at this time!
I can't see why, there is no B+ at the C26, measured to ground.
The voltage chart is on page three of the Rider's.
The B+ measured from the + side of C-26, should be around 240 volts, DC, to chassis ground.
