Hi Simon...agree with Terry above. Put the original IF tube back in. Lower G2 volts only affects the gain of the stage and not a major thing. I would not be too concerned with coil ohms....nothing open?
Check all the voltages for the RF/IF/mixer stages. The grids should be a little negative. The best tool to check IF and RF stages is a scope. So you have one? You can also try the old trick of placing another radio near this radio ( a portable) to see if it hears the osc....455 + dial freq.
