[Boatanchors] Seeking Transmitter Design Suggestions

[JAMES HANLON]

The WRL Globe Chief 90 was/is a 90 watt, 160 through 10 meter bandswitching CW-only rig using a pi-match output.  It has a 6AG7 crystal oscillator driving a pair of 807s in parallel and a 5U4G rectifier.  It would be a good rig to look at for some design ideas, especially if you are thinking of using 807s or 1625s.  You can get a manual for it from the Boat Anchor Manual Archive at https://bama.edebris.com .  From the home page select WRL, and then Chief90 from the next screen.  There are manuals for a lot of other good vintage rigs there as well.  Another to look at would be the Eldico TR-75-TV5, a 6AG7 to single 807 rig using pug-in coils.
