Marty (and others):

The power transformer in the DX-35 was "red-lined" even when the 
transmitter was unkeyed. It was common to lose the power transformer in 
normal operation of those rigs.

I lost two within two years of first building mine in 1956/57. I finally replaced it 
with one from a console TV set.

Although those in the DX-40 were running considerably more conservatively, 
in recent years, those have been failing with increasing frequency.

I fear that you will have difficulty finding a good replacement, and you might 
consider my +50 year old solution.

Sorry to be the bearer of bad news.
