What the...? I didn't know they MADE Vibroluxes in 1980

I stopped by my local store the other day, and sitting on top of the reissue Vibrolux Reverb that's been sitting there for a few months (partly because I can't afford it) is another Vibrolux Reverb. This one looked a little weird; ostensibly blackface cosmetics, but over-simplified and cheezy-looking. Checked in back, usual tube complement, few 9-pins, pair of 6L6s, tube rectifier. Normal VR control layout: 2 channels with volume, bass, and treble, plus tremolo and reverb on the second channel. But it has a "pull boost" function on the effects channel volume control. WTF?

I added all this weirdness up in my head, and concluded it must have been built in the early '80s. I know Fender built some pretty good amps in those days (what we call the Rivera era): the 75, WahWah's Super Champ. However, despite its pull boost switch, this amp obviously didn't get the full Rivera makeover.

Does anybody know anything about these amps? Any good? Similar to the silverface amps of a few years earlier? Cold and sterile compared to original blackface amps? Anything super-weird about them, like ultralinear outputs or any of that nonsense? What do they look like inside? Eyelet boards? PC boards? Mod-able back to older specs?

Physically, it's in nice shape. Literally sat in the basement of a little old lady, whose son played years ago, and then it went unused for 25 years until she decided to trade it in on a iPhone. They have is tagged at $500 (compared to $900 for the new reissue) adn I'm sure I can get them down lower.

Since my one-and-only amp is a tiny little 13 watt Marshall clone, clean headroom is not something I have in abundance. I've know for a long time that I need a Fender, and my modest volume needs would let me get away with a 50-watt Fender and still have it qualify as my "clean" amp. A Super Reverb would be really cool, but size and weight point to the Vibrolux as a better solution. This oddball one might be an inexpensive way to get me into a VR, espeically if it's either a bang-for-the-buck sleeper as-is, or can be converted to one with some simple mods.

Tell me what you know.

i don't know anything about that amp but i do know you are the right guy that should have some sort of Fender clean tone in your collection...

Get it and if you get tired of it sell it to me. Even though 80 wasnt the cream of the crop year for V-Luxes, it happen to be the year I was born and you know my love of the Lux. That is an insurance policy for you. If you dont dig it, you automatically have a buyer- ME!

Second series blackface

The Blackface cosmetics were reintroduced in the mid 1970's in a series of amplifiers designed by Ed Jahns.

These amplifiers didn't yet render obsolete the Silverface series and manufacturing of both co-existed for years.

The new Blackfaces came in varying cosmetic styles. The styling didn't become consistent until the early 1980's, at which point all these designs were already discontinued to make way for the very similar looking "II Series".

1978 - 1982″silverface” circuits with push/pull volume boost

Blackfacing

The blackface circuits AA864 or AA964 are often targets when blackfacing silverface VRs. We’ll describe the changes that followed after AA964.

AB568 vs AA964

The GZ34 rectifier tube was replaced with 5U4GB meaning more sag and less attack. You can select which one that matches your tone and style.
Bias electrolytic cap was changed from 25?F/50V to 50?F/70V in AB568. Tone not affected.
Voltage divider resistor in filter cap circuitry was changed from 10KOhm to 4.7KOhm.
10KOhm resistors in bias circuitry were introduced, as well as 100KOhm resistors to the 6L6 grids before the 1.5Kohm grid resistors. In AA964 there was just one common DC feed wire to the 6L6 grid resistors.
2000pF caps were introduced on 6L6 grids to filter out high frequencies, resulting in a cleaner sound.
150 ohm cathode resistors were introduced for robustness and safety and a 5/25V cathode capacitor was introduced to clean up distortion.

Those very late 70's/early 80's Blackface Fender amps, the "classic" ones like Deluxe Reverb, Vibrolux Reverb, etc were the worst of the worst...terrible construction, horrible lead dress, junk transformers, terrible cab construction, crappy speakers....

CBS was trying to go back to what they felt like players wanted simply by putting a blackface plate on them but they are terrible amps...all the of the worst parts of the Silverface era stuffed into an even worse built amp with a blackface...

It may be a silver face that has been blackfaced?? The SF vibro's were made until 80 or 81. The early SF are better(around 68 through 73). After the early 70's they added a MV & a few other odds & ends and it started the deterioration of these great amps.
