Vox AC30VR, 2009, PbF

Firstly does VR stand for Visual Replica, LM3875 amp with 1 valve, a bit smaller and lighter than the original. Originally thinking channel change sw prob as dirty ch good, clean cutting out (with owner). All PbF looks good under magnifying ispection lamp, any known stock fault?. It looks like return to engraving tool with nylon tip rattling pcb while listening to output on phones technique to zero in + redo usual suspect solderings

Genuine schematic on

no reference to the mini-reverb unit though.

15 V "HT" to the valve Looks like pot rivet problem and a PbF problem

Another eyelet problem with PbF, this time double sided tracks and contact failure to tracks on component (mainly) side, requires remedial pin works and resoldering relevant pot pins top and bottom. Absolutely no original solder wetting of the "blind" side at the pads, no plate-thru of the pcb ?
