Yeah thats bad if you only have 3 wires to the whole output tranny. If your talking about the three wires comming out of the hole closest to the pots. That is your output primaries. I cannot be sure beucase I dont know what transformer your using, nor have I assembled the 100w. It looks like your talking the equlivelent of step 5 on the JTM45. Two of the wires look like they each goto pin 3 of the correct tubes. The white looks like it goes to a filter cap.

Novosibir chime in anytime you feel free

Basically - when anybody is asking for help or advice on the board, he should post also sufficient informations.

Axeman shure knows his own amp pretty well - but we can't look into his head and only can guess, about which amp he's asking for...

... is it a Marshall at all? And if so - is it a 50W or a 100W - with original, or with Heyboer, or with MM, or with Fuzzikuzzi out of the hell trannies?

So please use your brain a bit more in the future, if you're asking for help and keep in mind, that WE ALL don't sit in front of YOUR amp!

wow, charming response
correction, it is the 100W plexi 1967 kit from George
i said output transformer, and in total it has 7 wires. 4 are the thick ones that are going to the impedence switch, the others, thinner ones, are a red, a brown and a white wire... not sure where they go on the board etc

Chill dude hes just excited to hear them tunes. The white wire goes to the positive closest to the presense knob (look at picture in step11). In the same picture its very clear which wires the red and brown are and goto. The red goes to pin3 of V5 and the brown goes to pin 3 of V6. Also you see the jumpers going from the two inner tubes at pin 3? They go out and get V4 and V7 the primaries too!

If you look at the 1959 layout by dan S.pdf or so. You can see what I am talking about easier.
