The last two posts are way over my head, but I'll point out that G1 and G2 are -.8V and -.9V.
In addition to curing cancer and establishing world peace, this is what I've done this evening.
Tube:
- Pin layout is consistent with Tung-Sol, RCA, bunkerofdoom, radiomuseum diagrams.
- No continuity between any pins except the heater, 2 & 7.
Coil:
- I don't think there's a break in the coil. Lugs 1-2 read a consistent 10 ohms, lugs 3-4 read a consistent 78 ohms. Checked the continuity tester through a couple of resistors, and it reads "open" at 75 ohms and above. Visually all connections appear solid.
Changes in circuit:
- Ungrounded pin 8.
- Disconnected junction C5/C6 from lug 1.
- Connected pin 8 to lug 1.
- Connected junction C5/C6 to lug 4.
- Tested the unit.
- Reversed connections on lugs 1 and 2.
- Tested the unit.
Here are the last two versions that tested negative. Voltages are updated. Don't understand why there's 0V at pin 8. I'm going to let it sit for now and try to get the tube tested tomorrow morning.
Is this actually a hazing? Are you guys going to come back with, "Gotcha! Nothing was wrong except you forgot to plug it in!"
