Thanks for the info - great thing about this Forum is you learn things all the time. Realignment did improve the deflection with the chassis on its side but then putting the chassis flat on the bench the deflection dropped off again. It wasn't loose IF tuning slugs and I could reproduce the fault tapping the base of the EM34. Cleaning and tightening the valve pin sockets didn't fix it but resoldering the EM34 pins seems to have done the trick. Cheers, Jerry
