Re: Magnetron voltage check
“... Magnetron heater voltage is formed at the MD Board of the antenna unit and is preadjusted at the factory. Therefore, no adjustment is required. However, verify the voltage as below...
... Confirm that the multimeter shows 8.0 V ±0.1 V. If it does not, adjust potentiometer VR801 on the MD Board...”
Since you're satisfied with the unit's performance, it seems like a rather unnecessary
“belt & suspenders” approach, to me.
"If you didn't have the time or money to do it right in the first place, when will you get the time/$ to fix it?"
