Used them myself - very useful - curiously, on the front panel they were a PIA - just got in the way all the time and looked 'industrial' even on the big 40kg amp - meant to add wheels ...

.. I meant to add -

I was poking around Alixpress last night and came across some neat products that combined Soft Start and DC traps - included small transformers rather than the usual resistor divider/cap system - of interest?

Do they provide circuit diagram?

I'll see how the simple passive thermistor goes, but I like the idea in principle.

A transformer is basically for life so I feel it's a good investment to get exactly what you want.
Yes I know, it makes sense.

Went and bought handles.
Drilled out new holes.
Mounted handles.

Prepared surface for painting but I might change my mind out of laziness.

Thanks to James for encouraging me to put the handles on.

These monoblocks are gonna be bloody heavy and I'm not getting younger.

Yeah, 'that's the go' - saves an enormous amount of agro later

About the Chinese dc trap/delay boards - no circuit but simple design - it looks like a copy of Per-Anders unit but not as good quality components/pcb - not really cheap either!

I'll hold out on active soft start till I've tested passive thermistor setup.
