For your perusal offered here is a nice 1966 Fender Vibrolux Reverb. There’s no date stamp visible on the tube chart, however the inside of the chassis has the rubber stamp and the serial number confirm when manufactured. The electric cord has been changed to a grounded one. The original grille cloth is mostly clean, save for a couple small holes, the tolex covering is in nice shape with a few bumps and bruises, but nothing glaring or reflecting abuse. The original Jensen speakers sound great. The transformers are all original, with date codes all in 1966 except for the output. I have had the amp for 35 years and never changed any major components, but although the power transformer has the correct Schumacher part code for a VR, the date code appears to be from 1971. The soldering on it looks factory, and it has cloth wires as used in 1966.

The amp is working and sounding very good, loud and strong through the Jensen speakers, and the reverb and vibrato work well with the original foot pedal (missing bottom cover) as shown.
