Hi.

Ben, that's interesting to see the Pong game for the ITT and I was also unaware about that. Thanks for the pics.

Frank, yes, the line whistles (magnetostriction) in the coil ferrites, was a common problem and again yes, PVA glue was recommended namely Resin W by Evo-Stik. I remember coming across various sets that had been in the hands of cowboys and in one set, the singing coil being silenced by a hewn block of wood wedged between the chassis and the offending coil. An effective bodge

Regards
Symon.
