Advice needed. Terminal 46 over limit for resistance check.

You’re right about the 130ohm resistors.  Only one could be read while attached - the only good one.  3 are toast.  Based on what’s online, does it matter what wattage rating I replace them with?  This may have been my problem from the beginning.  I’ll replace them and report back when installed.

I really do appreciate your advice.

That issue will happen either from the 2A3 insertion as I mentioned, or from backwards 100uF/450V caps, which act like a short when installed backwards and destroy the 130 ohm resistors.

If you use 1/2W resistors, they will probably last a few days/maybe a week.  A 1W resistor around a year or two maybe, and a 2W resistor indefinitely (other than failure from fault conditions of course).

Another request for advice after installing three new 130ohm resistors.  The good news, my initial problem is fixed.  I think.  A new one sprung up though.  At both terminals 4 and 17 I get fluctuating DC readings (trending up over time).  Measurements ranged from 8 to low 30s after a second reading.  29 is also not zero.  It is -1.  Do you have any ideas or thoughts? 

Once again, thank you for helping me get this one over the finish line!

What are the units on this reading?  Is that 8 to 30 mV, 8 to 30V, etc?

29 connects to all sorts of terminals via the buss of black ground wires.  If it doesn't measure exactly the same as any of the terminals its wired to, then there's a bad solder joint along that string of black wires.

[CuriousMister]

The readings at 4 and 17 were both in mV.  I’ll do some joint management on the black wires connected to 29 like you suggested later tonight.

[Paul Birkeland]

0.004-0.017V is close enough to 0V to not worry about in that spot.

[CuriousMister]

I think we are golden! I measured all the terminals connected to 29 by black wires. They are all effectively the same - between 0.7-1mV. Would you say I’m ready to move on to the hum test now?  SO thankful for your trouble shooting.

[Paul Birkeland]

Sure, that seems reasonable.
