Model 90B Tinkerer
#28

Well your suggestion to check the osc freq tracking with the dial was a good one; I loose coupled to the osc. tube, and it went like this:

Dial    Osc

600  +180
700  +189
800  +148
900  +120
1000 +95
1200 +15
1400 -74  (yes, -74)

The dial needs some set screw adjustment, but this does show the tracking is way off.
I think I shall meander the I.F. back up, and see if we can get the tracking where it should be.  And, maybe reception will come back.
Thanks Mondial Mike,
Simon
