OK, I have a Hallicrafters SX-111 in very nice shape. It has been recaped but I am going over it and realignment before I offer it up for sale. My question is, the 6BY6 mixer was replaced with a 6BE6. I can not see much differance. Is there any advantage to doing this? I did search the internet and found some answers but wondering what this group has for thoughts.

I would leave it in if the conductance checks out on a tube tester.

They 6BY6 has slightly higher conversion gain and slightly lower inter-element capacitance than does the 6BE6, so there is a slight operational advantage of the 6BY6 over the 6BE6.
