Maybe get an eye test. Boots do a really thourough one where they can check for abnormalities with your retina and stuff.
Also get straight back to your GP and get some more tests done…especially if it is worse and you have had a seizure – something is obviously not right (and Yahoo is not the way to get a diagnosis!)
Good luck

What’s the difference between a tube and a solid state guitar amplifier?
I know tube sounds better.
I’m probably going to get a little technical here, but stay with me.
First, you can’t make a blanket statement that “tubes sound better”. I’ve heard some very good solid state amps in my day, and some really horrid tube amps. So, just because an amp has a tube in it doesn’t automatically make it a tone machine.
I’m going to assume that you question is asking “What’s the difference in the tone of a tube and solid state amp”, so that’s the avenue I’m going down.
For the most part, tube and solid state amps will behave much the same way while they are being operated in their linear region, which is a fancy way of saying that you haven’t turned it up loud enough to distort. Tube amps, in general, have a higher input impedance than solid state which tends to load your guitar pickups less (and thus will sound a little different).
The real difference comes when you start turning up the signal level to the amps, and how they handle the overload.
A solid state amp will keep amplifying a signal right up to the point to where the amplification device (transistor, op amp, FET, etc) runs out of headroom. And at that point, it abruptly stops. This results in a clipped waveform (think square wave) that contains predominately odd number harmonics. Our ears perceive this kind of distortion as abrasive, or non-musical. It’s the way a lot of fuzz and distortion pedals work.
A tube, on the other hand, does not behave like this. As you turn up the signal level to a tube, it’s starts to compress the signal. As you turn it up further, the tube does not clip the signal as abruptly…it’s more of a limited signal than clipped. Combined with the output transformer in the circuit the signal consists of predominately even numbered harmonics, which our ears perceive as musical.
Tubes (power tubes specifically) can have a very large dynamic range…much larger than solid state devices. This contributes to how a guitarist can back the volume on his/her guitar down a bit and clean up the sound.
OK…probably way more info than you wanted, but there you go.
wiring a 4 channel amp, but only 1 preamp out from head unit?
my head unit only has 1 rca preamp output, and i need to hook up a 4 channel amp. Do I need to get splitters?
You will need to split it however, you wont have control over the subs or speakers as there own entity. You will be controling whatever speakers you have connected as though they were the same one. So i would just get a new deck if that is the case.
