Vox AC10C1 won't power on
Hi folks,
As the title says, the amp won't power on...
I already replaced all 4 tubes with some nicer Tung-Sol tubes and swapped the 2 fuses I could see on the board, even though I don't think the original fuses were bad...
What's the next likely possible issue? Unfortunately I don't have a multi-meter and honestly wouldn't know how to diagnose it of I did. (But I could grab a cheap one if someone has some easy steps I could follow to diagnose)
Any suggestion would be much appreciated. Trying to avoid a costly repair from a local music shop.

Is it plugged in?
Lol. No but seriously probably a transformer. Awhile back I had bought a brand new Peavy valve king and like a year after I bought it. No sound. You could see the power light on. I knew it was getting power. I swapped power tubes and pre amp tubes and every tube in the thing. Turned out to be a transformer. Luckily it was still under warranty and it was repaired for free.
I suggest unless you're technically trained dont fuck with it. Take it to be repaired. Transformers can give off a really big kick. Probably would not kill you but potentially could if you slip up.
Were you still seeing the LED light up? Im getting nothing at all. The day before, the sound output was really low... I thought maybe it was a bad cable somewhere in the signal chain but then it died all the way.
Yeah I think it was like 99% but this was a couple years ago so im not 100% sure.
I had the same issue with my sound just fading out then it was gone. I tried swapping cables. I even took the input of my guitar out to see if it came unsoldered. Will probably be a couple hundo to get fixed. But if I were you I'd bite the bullet and get it done professionally. That way if its still not right you have someone to fall back on. And it sounds like you did all the simple things that would be a quick fix.
