Does anyone have any information on either of the following transformers: 


*	Newton Engineering Services NES-5400
*	Newton Engineering services NES-5401


These were used in an 8877 amplifier manufactured by RTI, Inc. Tere were
probably a very limited number of these amplifiers made.  I know of two
others, but neither has tech data. The amplifier is a reentrant cavity
tuning 135-155 MHz.  The power supply is separate, and currently is wired
for (and appears to be designed to run) on 115 vac 30A service.  I would
like to convert this to 240 service, but don't want to start hacking until I
learn a bit more about the things. Pictures are available if needed.

Even better yet would be any technical information on the amp and power
supply. 

Thanks in advance.
