Standby indicator lamp resistor

I as noted in the tone circuit rebuild thread, my standby indicator lamp was not working.  The resistor connected to it has tested bad, there is no reading.

The schematic calls for a 180K and according to the notes 1/2 watt.  The one I took out has only 3 bands. Brown, grey and light gold.  Unfortunately according to the charts/calculators this is only 1.8 though maybe it's not gold?  It is not yellow which would be 180K.

I assume going with the schematic is proper?

Re: Standby indicator lamp resistor

I just rebuilt my '70/'71 and used a 180k per the schem..  All schems on here show 180k with the exception of one which shows 120k (which is the '71 vt40)

Re: Standby indicator lamp resistor

I figured it's the way to go.  The one I took out and it's colors may just be a fluke from when it was built.  I'm rather certain it is the original resistor.

Thanks.

Re: Standby indicator lamp resistor

Yeah it's 180k.  You can put a 1 watt in there,  might help keep it working longer.

Re: Standby indicator lamp resistor

I just put in the resistor and the light works perfectly.  Now unfortunately I have another problem with it popping/cracking when I turn it on.  Channel 2 is weak (needs 12 o'clock to sound like 9) and the sensitivity switch pops loudly the worse when going to zero.

But, the lights work and the tone controls seem just fine.  It's going to my tech now as this is beyond me.
