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 |

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 ? |
