Looks like an AC30But no it is a modelling amp with a couple of tubes in the preamp (Stereo)Rear viewChassis out..Big…OK how to get these tubes ut to test… cannot grip them.. I had to take the chassis apart to take these out… horrific design!PCB out now I can test the tubes and check the soldering for issues. Nothing obviously wrong.. Put all back together and all tested good!Heavey pedal board totally dead….Connector now directly soldered to trackPCB track broken away from the connector… so no power getting the board at all.. easy fix everything tested good Vox Valvetronix amp in with an intermittent issue and a dead pedal board. Got her going though she was a pig to work on… Puch prefer the made in China AC30s which are a similar price..
