In this case I decided to pair my 6J5/6L6 transmitter up with my HRO Sr rather than my Simple Superhet. I wanted something of the right design vintage and looks to sit next to my HRO while running either barefoot or driving my TZ-20 amp. The core design of my 6J5/6L6 transmitter is right out of a 1940 Stancor manual so the design was fine. It just didn't look like it belonged with the HRO Sr. What I did was a cosmetic change replacing the front panel and then repackaging the transmitter in a metal cabinet.
If I ever need a more upscale transmitter in that spot I have a Meissner Signal Shifter waiting in the wings.
