Hi All I am building a XV-144. Got to alignent and testing, LNA Bias. Adj R-13-No voltage at TP 2. voltage at r12 =0 Checked resistance to gnd With DMM at R-12 249 ohms at D3 145 ohms at junction of R15 & C2-103 ohms Reversing the probes I have the same readings. A bad Q3 ? Maybe some one has had the same problem. Thanks Phil
