I have been watching this thread with great interest. I have been thinking about doing this mod for some time. It seems like there is always something more pressing. Ron, I know you did one of these in the past and was disappointed in the performance. That made me start thinking about going with a converter tube rather than separate oscillator and mixer tubes. This would free up a socket to add an extra stage. I had thought something like a 91 with 2.5 volt tubes And no P-P output.If this mod works well I will copy what you have done.
