I am scratch building a grounded grid preamp using Triad vpt230-110 and vpt24-1040 transformers. Being largely ignorant of the basics of electronics, I am having difficulty determining which wire go where. For both transformers the data sheet says:
Input: Series - blue and brown, jumper gray to violet
Parallel - blue and brown, jumper blue toviolet and gray to brown
Output: Series - black and yellow, jumper red to orange
Parallel: black and yellow, jumper black to orange, red to yellow

Attaches are the data sheets hopefully. Thanks for any remedial help you can provide.

Depends where in world you are, what is your mains voltage? for the primary connection.
The secondaries for the GG are 115V & 12V, so wire in parallel for both. A web search will provide plenty of information for this.

Thanks for the quick response. To be more specific, I am in the USA (120V). For T1 and T2 input, I believe the blue and brown wires are connected to the hot 120V input and the violet and gray wires to the negative. The output black connects between D1 & D2 while the orange is between D3 & D4. Red and yellow between C4 & 5 and C6 & 9 respectively.

T3 input identical to the other transformers. T3 output I am not clear at all on as I do not understand the meaning of jumper here.

I expect these are basic concepts, but they are unclear to me.

Thanks for any help.

Not quite right. Reading this page should help you understand.
All connections, both input & output, should be connected in parallel.

Thank you very much.  This is a big help.  I might actually learn something by the time I finish the project.
