hi folks,ive got a tec 453a-1 to fix,it has no trace,ive looked at the voltages on the psu low votlages board and they seem fine as far as i can tell,all the manuals i seem to get are for a 453 but not the same model,ie mine has no beam finder button or scale illumination pot,can anyone help on this.? anyone know where i can get the manual for this,one of the boads has a 1970 date on it so i assume its a late model. manual,cheers m3vuv?
