1968 Fender Bandmaster Reverb TFL5005D
2-ohm * 40(+) watts * Silverface Drip Edge Amp Head
Early 1968 AA768 version
AB763 Blackface Modified
Hello. This is a very special, very early 1968 Fender Bandmaster Reverb TFL5005D amp head.
Although the original amp restoration tech speaks several times the amp is an AA568, I'm not
sure. I believe it is an AA768. You be the judge. Did Fender ship AA568 Bandmaster Reverbs?
You will see there is extreme minimal rust or corrosion (the chassis straps have the obvious
wear). All other chrome has light normal wear, but nil corrosion. Please review the pictures
to see the chassis tray and tolex. Also, review the original restoration technician's below notes.
This Bandmaster Reverb amp is considered "Hot Rodded" and that is not by initial design.
First of all, it was modified to the special Blackface AB763 circuit change. The Bandmaster
was used on 4x10 and 2x12 speaker cabinets. The original transformers were not working
well (as described below) as the original output transformer had a short and the original power
transformer had power distribution issues. Therefore, replacement Mercury Magnets trannys
were used to solve the problems, while adding a more powerful 2-ohm handshake towards
the speaker cabinets.
Fender originally installed an incorrect "horizontal" reverb tank (as described below) into a verticle
upright position onto the backside baffle. This caused reverb tank problems Now our Bandmaster
Reverb amplifier has a correct newer Accutronics tank installed onto amp's inside bottom panel.
That is it! Things to consider are the transformers & reverb tank, which are much better than the
factory trannys & reverb tanks. Also, as you well know, all transformers and all reverb tanks, etc.,
do breakdown over time. Here, you have here a very strong clean player's Bandmaster Reverb
with newer, stronger components. I suggest you get a footswitch and an amp cover.

Early Blackline Faceplate
Drip Edge Grill Trim in great shape
* Wiring Resistors & Tone Capacitors are original except where general maintenance was needed,
* Rectifier = 5U4GB NOS
* Power tubes are older Sovtek 6L6's installed in 2009
* Preamps tubes from Sylvania~JJ Tubes, installed in 2009
* Reverb tank is Accutronics Reverb Tank installed in 2009
* Original Fender Choke = 022699/606821 = 21st week of 1968
* Original Reverb Transformer = 022921/606811 = 11th week of 1968 in great working order
* Mercury Magnetics Power Transformer Upgrade in 2009
* Mercury Magnetics 2-ohm Output Transformer Upgrade in 2009
* We used this sweet sounding 2-ohm Bandmaster Reverb to Drive 4x10 & 2x12 speaker cabinets
* This 1968 Bandmaster Chassis = same family as Fender Vibroverb or Fender Super Reverb
* Upgrade three-prong electrical plug
* No footswitch = a two button "Rev/Trem" RCA footswitch is required to operate the tremolo circuit.
* No inside cabinet piggyback knobs. They are missing or were not factory installed, and there
is no tolex wear for the side clamps or knobs. The reverb tank is installed on inside bottom.
* No amp cover
* Overall......a great amp....loud and tuneful! Everything works as it should. Everything else hardware wise looks to be original...even light corrosion on the top chassis straps. My inspection of the amp has all the original pots and faceplate controll knobs, choke, reverb tranny, tube sockets, bright switches, jacks, rear outlet, ground switch, back and face indicator panels, cabinet of course, and cabinet hardware minus the knurled hold down knobs. I can't attest whether the knurled knobs even came with the original AA568 Bandmaster Reverb, similar as the discussion on Fender Showman Reverb amps.

Comments & Notes form the Amp Restoration Tech, from whom I purchased the Bandmaster Reverb from:
***The following information I stand behind. It is important you the buyer read the notes BEFORE YOU BUY.
Question * It looks like this Bandmaster originally had the AA768 circuit. I know you described that there are some mods to change to AB763, but the bias section appears to be set up a bit differently. Do you have a list of exactly what changes were made?
Answer * Yes originally AA568. At the phase inverter, I always flip flop the 100k/82k and 220K's. This allows shorter grid wires to the power tubes and eliminates any chance of potential parasitics (removes approximately 8" of grid wire). Other than that, the circuit is the same as the diagram for AB763, but the layout is slightly different.
Yes the reverb tank is working. Fender originally installed a back-baffle mounted reverb tank that was part-numbered for a bottom mount reverb tank installation. The original Fender did not work well. It appeared fender assembly was in error and mounted a vertical when in fact it is a horizontal type. Therefore, I have the better bottom mounted Accutronics installed on the bottom.
The original power tranny worked, but gives off a lot of eddy currents. This is a magnetic field which interferes with the component board working as well as sucking power from the amp because the power tranny wants to work at producing "eddies" (phantom magnetics) (vs) providing power to the amp. The original output tranny had a short in one leg of the primary and needs to be re-wound. The Mercury Magnetics upgrades were due to the tranny problems.
The tolex has only light normal scuffs for this beast. Except for a small burn mark (that’s not that bad), there are no other major issues. Straps, hardware, chrome ~ are original to the amp, including the back panel screws. I did add period correct washers on the screws, but you can remove them if you want.
I purchased this amp from a local steel guitar player in 2008 who was the original owner. Everything looked reasonably original at that time, except for a few resistors and caps. The Bandmaster needed a bit of TLC maintenance that was long overdue. The chassis number is A32718 and stamped on inside as you can see by photo of the guts is "68". There is no is circuit number on the label inside the amp so I can assume it's as you say AA568.
There are no side bar clips on a bandmaster reverb (bandmaster, tremolux, bassman). They’re "through hole" knurled knobs inside the cabinet and are missing. I've seen these on ebay original fender parts. I imagine they were removed when a newer reverb tank was installed covering those two holes.
The early circuits were a bit confusing. Depending on what reverb tanks were in stock at the time of build, many were bottom mounted and the pre-drilled holes were not used. I believe this to be the case here as well as your showman you mention. The bandmaster reverb probably hit the streets between AA568/May 1968 and AA768/July 1968, varied depending what was in stock at time of build. CBS Fender as experiencing decreased sales and was pushing amps out the door as fast as possible. Marshall was nipping at their sales numbers. It was the time of music where playing loud was fashionable and Marshall had the big boy 100 watters that were leading the market. Fender used what they had in stock to keep up!
Everything else hardware wise looks to be original...even light corrosion on the top chassis straps. My inspection of the amp has all the original pots and knobs, choke, reverb tranny, tube sockets, bright switches, jacks, rear outlet, ground switch, back and face indicator panels, cabinet of course, and cabinet hardware minus the knurled hold down knobs. I can't attest whether they were ever there based on our previous discussion and your inspection of your showman.
The reverb tank installed does qualify as a good replacement part for this amp. The original can be rebuilt but would take some doing. The transducer wiring is quite thin and is difficult to solder to, but it is possible. You might search for a working period correct pan first from a reliability viewpoint. Any Reverb Tank number 4AB3C1B tank will work with this unit (flat spring down mounting, horizontal, 2250ohm/8ohms.
