Toroidal PT wiring and safety questions

[JohnnyCrash]

So... am I missing something?

I just got the toroidal Rob recommended for the Micro Bassman.

Do I have to do anything special to mount the PT and avoid having this thing blow up like a Harry Potter wand?

To aluminum chassis you can use only rubber plate in between. Steel bolt thru hole is fine and steel plate on top and also rubber plate between. I have not used toroids on steel chassis but there I think rising using something plastic, wood etc could be good?

Yep, bolt goes through plate, then rubber disc, then toroid, then rubber disc, then chassis, then nut.

old thread but I am about to use one of these for the first time.
Do you mount it with the wire side up or down?
If down, dont the wires get mashed between the pt and the chassis?

You can mount it either way, and people do. Wires down, on chassis, appealed to me, and the toroid is tapered so there's room for them.

If living I Europe I can rally recommend Petra Toroidal from Romania. The makes the transformers on demand. Unfortunately no SE OT’s but for PP. just ordered 5 different. Three PT’s (one for @robrob stereo amp, one for a GA-30 build and one for an Ampeg B15-NC. Two OT’s (GA-30 and a HIFI sort of fo the Ampeg build with 20Hz-20kHz) total price €300 (same in $)). Really like them Toroidal but ugly and always makes me think of Simpson. Need to find some sort of cover.
