Hickok TV-7/U owners

You can find TV-7 data online at the following site:
Nolan Lee's TV-7 page

Here are the settings for a 7189 based on the data from that page:

7189 6.3 EV2-7930 10 - D3 46

---Gary

6bq5 is: 6.3 EV2-7930 30 C (press 3/minimum 50).

But, best to wait for someone to confirm the settings.

Yes the shunt setting is actually -. I assume it would be best to set it at 0 although it could mean that the shunt is irrelevant. I guess you could test it by trying different settings and see if it changes the tube's readings. I'd gradually turn up the shunt setting if you do try it. It's always a drag when something blows up.
