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

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 ?
