To be cleaned. |
Restored. |

Mark how it goes back in. |
 |
This is stuck. I could not adjust FL2 during my preliminary
algnment. |
I do not know what I am getting into. Mark each section. |

Pretty simple looking. |
I will clean off my marks on the chassis top. |
I could not resist using Brasso on the threaded rods. |
I cleaned the whole thing. |
 |
Easy to turn. |
Nice. |
I'm happy. Now back to the sweep generator. |
This is the sweeper set up. The top generator sweeps the VCO and
the scope's X axis. |
Ringing is from a fast sweep. And the two separate peaks.
One going up in frequency and one coming down. |
The ringing dissipates and the peaks merge when the sweep rate is
slowed. |
Use the VTVM on the specified test point along with the scope Y
axis. |
The sweeping allows quick location of the filter's peak
response frequency. I confirmed this peak by varying my HP606. |
This unit FL1 and 2 easily peak.
|
Tomorrow is another day. A full accurate and precise alignment!
