[QUOTE="Steerpike, post: 69311, member: 807"] I didn't want a second post - i wanted to append to the above: Anyway... It seems to have too few turns for it to have any significant electrical effect except at MHz frequencies. On a transistor amp there's often an inductor in series with the speaker for stability with capacitive loads - but that valve output transformer is of such high indctance, a tiny coil like that is almost insignificant. I see no selector for speaker impedance. Maybe that yellow wire can be moved to other transformer taps for other speaker loads. Pye became a subsidiary of Royal Dutch Philips at some stage. [/QUOTE]
