Another 2-1/2 hrs over at JBs workshop.. which is the furnace room and toasty warm.
Below are the
four cap leads and the
ground bundle with heat shrink applied.
The copper tail is to the LEFT, and the power transformer center-tap wire (YELLOW stripes) was soldered to the GROUND bundle.
Remembered to bring the
heat gun today to `shrink the tubing´ on the C210 cap cluster.
Here is the cap cluster test fitted into
original C210 can (gutted).
Next the can is reinstalled into the spring brackets and cap cluster gently stuffed inside.
Have to say I like the way it came out.
The
copper tail from the ground bundle is now connected to the
transformer mounting study with a bare ring lug.
All work was checked and double-checked for correctness.. and then power applied.
16 watts idle power seems low compared to my MR77 which draws 40-45 watts.
Voltage check of the primary power supply section looked GOOD.
John says he connected it to the system in his study and the hum/noise were GONE. I have an idea the PS ground wasn't right, and of course the old clunker cans needed to be replaced.
How many hours do we have into it JB? 30? since last spring? One of these days we'll have to get a pizza.
