Heads up for anyone restoring or repairing one of these old Adventurer CW transmitters. I assume people with issues might find this in a google search. The meter shunt resistor values were changed during the production run. My TX is serial 81000 range and the manual that came with it from previous owner that worked on it is for a late 84000 range In the earlier ones, the grid shunt R4 is 1K and the later value 200 Ohms. The earlier plate meter shunt R5/6 is 50 Ohms, two 100's in parallel. The later production is R5, 10 ohms. I found out by accident as the previous owner did some repairs and put the 10 ohm shunt in, and I could not get a correct plate current reading, even though the power output was nominal. Apparently the older meter was less sensitive. And conversely, if you installed the older values into a later radio, it might peg or damage the meter. The manual I have lists the later low value resistors in the parts list and the large schematic. The older values showed on the small schematic on the glossy advert. handbill page in the front.
