[R-390] Testing the 2nd osc, swapping xtals

[dog]

Got the new 5654W tubes today. 3 of the 4 are much better, they appear 
to be GE. One is crap. In the EAC, it makes spec everywhere, 8MC is 
worst at -4.5V. But in the Dittamore the tubes didn't do anything. So it 
looks like that RF section needs to come out and replace the bypass and 
feedback micas and anything else that strikes my fancy. Haven't worked 
on the high voltage 1st osc in the EAC yet. That tube is really hard to 
get to.

It's almost like in both RXs the same frequencies in the 2nd osc are 
low, it appears to be a pattern. 8, 15, 17, 23 and 24 are low, and the 
very high freqs, 25 and above, are high, over -7V. It would be 
interesting to know what the voltages were when new.

I didn't notice that swapping xtals did anything at all. But I also 
haven't tried just an LC circuit in place of the xtal.

I'm actually caught up with the mowing. With all this rain we've been 
having the fields are full of some sort if invasive creeping grass 
undergrowth. I usually mow in 5th (out of 8) gear, I had to mow in 3rd 
this year. I can still mow 10 acres in under 5 hours. Now I've got the 
little fields to do and they're a pain.
