Default Old Marshall plexi clone problem

So, I got this amp 2 years ago, traded a ProCo Rat clone and 6000 dinars (about 70$) for it. Great plexi tone and very loud. I think it was made somewhere in Yugoslavia, probably in the '70s. It has some weird tubes in it - 3xECC83, 2xEL503 and one ECL82. Had no problems until now... Turned it on the other day and there was no guitar sound, just a moderate hum that got a bit louder by turning the volume knob. I tried changing the preamp tubes but no good. Any ideas?
