[QUOTE="MusicMan_ZA, post: 1073692, member: 14924"] Thanks Handsome. Yes, the AC in (blue and brown) goes, via an on/off switch and a 2A fuse on the brown leg, to the PT primary. The PT secondary 6.3VAC winding goes to all the heaters, and the PT secondary 280VAC goes to the 6A FWBR. No mains earth wire connected ATM. The EZ80 valve rectifier is not in use ATM. On the tag strip where the incoming AC connects to the PT primary winding, each leg (blue and brown) has a small 10nF cap connected to ground. This is as per the original arrangement. [/QUOTE]
