Need to convert a Linar preamp from 220V to 120V
I have just acquired a Linar model 2 preamplifier that is configured for 220V.
I can see that it is using a dual primary toroid, but I am not 100% certain about how to go about reconfiguring it for 120V.
It looks like the primaries are wired in parallel.
I have attached a couple of pics to illustrate my situation.
The white and orange are connected to the hot and the black and brown are connected to the neutral.
Any help is appreciated. I will call Linar as soon as I can to confirm, however it is my impatience that is creating this post.
Is this how you received it ?
It looks like it is already set for 110v as both primaries are paralleled.
It's dangerous as it stands. The bare wires need insulating.
The bared wire is my doing, for the picture.
They were taped up. I will be replacing the tape with heat shrink.
I think you are right about the conversion already being done.
I have no way of contacting the previous owner to be sure.
My understanding is that the primaries are paralleled for 110V and in series for 220V.
I know I need to brush up on power supplies, I've been lazy.
