The following chart, was originally printed in VG magazine, by Gerald Weber.

If you see any data that is not listed here or notice any errors, for 1970’s and earlier Fender amps, please send us an email and we will update the chart.

I know that's a lot for a first post, but I've been pestered. The EIA manufacturers codes stamped on the trannies and the pots are your best method of definitively dating this amp.

I've also read that early TFL 5000Ds have been identified that may have one of several circuits-how can one identify which?

Finally, there is no "dual" mentioned on amp, tho' these are always identified as "Dual Showmans"-are all silverface showman reverbs "dual amplifiers"?

The Vibrolux is quite similar to the Pro Reverb 2×12″ except for the smaller speakers, output transformer and power transformer. 10″s provide a more scooped, responsive, punchy and sparkling sound than 12 inch speakers.

The 12″s are fuller, warmer, looser in the low end while having more mids and a more three-dimensional tonal spread.

Fender switched back to the blackface era cosmetics some time in 1980.

Twin Reverbs produced between late 19 have a black control panel and silver sparkle grille cloth.

In modern times where low wattage breakup has become desirable, the Pro Reverb has become very popular.

The 2×12″ speaker configuration can deliver lots of punch and powerful mids that cut through with a good sound spread on stage.

Remember, your amp is newer than the newest component.
