Flea Update III - T1 high res pictures
As promised High res pictures of T1 winding.
I used 3 colour wires (this always makes identification easier).
Primary is Gold
Secondaries are Green and Red.
Green connects between LPF and Ground
Red +Vcc and Q1
Gold +Vcc and C3 (The trimmer)
T1 sits about 4mm above the ground plane held there by the wires solder points. I had thought about sticking an off cut of an old loyality card or credit card, my favourite insulator of choice, underneath it.
Thanks for the close-up pix of the main transformer Dom.
ReplyDeleteThe secondary Red and Green windings REALLY are in the same direction. The connection from Red secondary winding cross over underneath.
