Amp switcher there are lots of different ones, this one is just an example of what you need.
hi, not at same time one at time. Tks
there is one cheaper?, if one is off when the other is running, can i use a one like this

Ok, then for starters you need to be 100% sure the unused one's output jack is not connected to the other amp's output jack at any time. Never, at any time, whether it is turned on or not. And if the unused amp is on it needs a load of some kind, either a speaker or an appropriate dummy load. So you need to take care of switching at that end before you even begin to deal with the switching at the inputs, which is the easy part.
Please give us more specifics, starting with models and the output power of each amp.

Not for the part I mentioned, no. Please give us specifics on cab and amp model numbers and power output. There's a substantial risk of blowing stuff up and you need to do this right or not at all. Just buying and using a second cab is much more straightforward and definitely a better idea for most use cases IMO.hi, i've found this
could be a used for my purposes? tks

I'll look through the details on those amps later, neither is at all familiar to me. If it were me I'd definitely just buy and use a second cab though.
yes im think, but i havent enought cash

Then don’t waste money on an unsafe and/or half baked solution, do it right or not at all.

You’re looking for something like the Radial Headbone.
It’s expensive though, so you’re probably better off buying another cab when you’re able to afford it.

There’s nothing on the DIY market that does this though.

Headbone VT - Radial Engineering
The Headbone VT is a specially designed switching device that lets you toggle between two different tube amp heads while using a single speaker cabinet.

Switching tube amp outputs into a single cabinet is both difficult and unwieldy for a DIY solution.
We're talking about relatively high voltage/amperage in the signals once we get into switching power amp signals. Any kind of switcher would need to switch each input between a cabinet and a dummy load.
There's a lot of traps to fall into here. Damaging the amps themselves would be quite easy if one doesn't have a firm grasp of how to handle the signals involved. The majority of the small signal switches that we use in this DIY space are not robust enough for this task: try running a power amp signal through a typical stomp switch and you'll end up melting the switch contacts.
TL;dr: this is a poor fit for the DIY space.

I don’t know I think you should give it a shot… what’s the worst that can happen?

Take a look at this picture of the guts of a radial headbone VT:
LOTS going on in there. Big traces for the power amp signal routing. 250vac/10amp rated relay handles the switching of the power amp signals.
It simultaneously switches the guitar inputs as well. Likely how they get away with such a small resistor as a dummy load.
It's possible to build one, but similar considerations would be necessary. This is more like switching line voltage than typical guitar signals: if you're not used to dealing with potentially deadly electrical circuits...well, you might want to see about just picking one of these things up used.

Well it doesn’t seem like he is into the sound advice so might as well give him some encouragement, besides that Bugera is going to catch fire anyway. I want to see where this goes.️
