ARC ref 110 tube bias prob

I would call audio research. In the past I have done this and talked with… the tech. Or email. But calling is quicker.

i have that amp, is that particular one new to you?

seems like when the last set of power tubes went (perhaps in the hands of the prior owner), they took out a biasing resistor in that quadrant, which will likely require the amp traveling back to minnesota

Yeah, I know I lent you my 2 cents in your original thread but I was wrong. I think only a circuit problem like the above referenced resistor could explain your Fluke reading. 

@jjss49 , I used to have a pair of ARC VTM120s that would take out grid resistors on the CB enough that I got proficient at replacing them. Is this biasing resistor in a difficult location to get to, or might it be something that OP could de-solder & then solder a new one in (instead of shipping it back to Mn)?

Thanks all. I called ARC yesterday and they are due to come back to me later. They asked me to check if the resistors nearest the last tubes looked burned out but they look fine. With the new tubes in the ref 3 and this 110 it sounds fantastic - cant believe what I’ve been missing but I guess there’s a problem I need to fix. I’m waiting to hear from ARC whether I’ll cause damage by using it like this.
In the UK I only have to take it 40 mins up the road to the UK importer but fear they’ll have it for weeks!

Not sure its something I should try and fix myself.
