[R-390] Tracking down low sensitivity 0 to 8 mhz problem

[Jacques Fortin]

Hello Jordan,

Happy to know that it works fine now.
When you mention C268 below, would you really mean C328 ??
A mica cap is mandatory for C327, I guess, what was fitted there before you
replaced it ???

Hi again group,

Ok..I'm now able to adjust T207 to produce -7.6 Vdc at E209, so the effort
has been rewarded.

I wish I could say for certain what the cause for the prior low output has
been, but I did not find a faulty component including coil resistances, a
bad cable or connector, or anything else. Even C227, the .047uF PIO cap
tested fine after I replaced it with a film cap.

I replaced C268 and C327 with Mica caps, an 82K resistor and thoroughly
checked wiring and switches.

The one thing I did find was that C275 had been replaced with a .0033uF cap
rather than the .033 called for. I'm not exactly sure what effect that might
have had, but there was a reason for the published corrections.

I'm going to do some contact cleaning and a little lubrication before I
re-intall the deck and move closer to the finish...
