Vox Supreme serial number 1030 preamp
currently in the UK
General pictures of the preamp - the original jack plugs replaced in the 1980s along with a few capacitors.
After these photos had been taken, the preamp was recapped - the yellow Lemco capacitors had entirely dried out. All is now in full working order.
The preamp is stamped in Type 2 format: "PRE/AMP. T SER No. 01390".
Pictures of the box, interior and exterior, are here. The power section is here.
