Not sure it hlps but pay special attention to 6A7.
Thing with those, the amp section that is used as RF-amp/mixer is often weak while the osc is good. While 1000 is new tube reading most will be below 700 and many belw 300. I enountered way too many of those.
This might impede amplification, especially when the 6A7 is the first tibe nd is the only RF amp.
