Oztules,
Your last e-mail was most useful and I have incorporated your comments about coils and coil wire sizes onto the schematic.
Can you please help with the following:-
Triac’s what size and amperage? Any suggestion for a common part number.
Voltage and amps.
Diac As above.
Diode D1 100 volt any preference 1N?
All resistors any wattage specification?
Resistors R4, R5 and R6 what size and wattage?
Resistors R1 and R2 what is the value and wattage, and should there be an R3 and R4? I’m confused on this part.
Toroid Can you provide some idea of internal and external diameter, and width.
The schematic seems to embrace everything so if you could peruse it from left to right to add any comments that would be very useful.
Readers should note that the circuit schematic has been drawn with Express Schematic software and I have also produced an Express PCB layout on mini board size. The PCB layout has been checked against the Schematic using the software to highlight all connecting parts. They all match – at the moment.
I have a coil ready for re-winding as the main power coil (ex microwave I think). The last awkward job will be to find an ETD49 bobbin assembly for the remaining Coils 1, 2 and 3.
So far so good, and nearly there.
I am always a little confused with Australian English. I am forever mixing up a tranny with a dunny. I suppose when has been zapped by your tranny one would need a dunny anyway!
