Fender "5D6" "DK" 4x10 Bassman from November 1954 (SN #0769)
. Trying to look up what that meant, and researching selling prices of other 1954/1955 4x10 Bassmans, I discovered Wikipedia stated only six 5D6 Bassmans were known. Wikipedia actually listed each owner's name ~ amazing!
* November 1954 Serial Number 0769
* November 1954 Fender Bassman’s Tube Chart Stamp “DK” indicates November 1954 production
* Date Code on Three (3) Jensen Speakers = 220443 = 1954/43rd week
Three (3) 1x10” 1954 Jensen Speakers P10R 220443 (reconed) Jensen Alnico-5 PM Concert Series Speakers
One 1x10” 1961 Celestion Speaker 220122 (P100, C7272)
* Output: 30W, Two Input Jacks, Two Volume Controls
* All Original 1954 Pots (Potentiometers) = Date codes: 304 412 thru 304 446
* Original 1954 Choke & Output Transformers
* Power Transformer = Chicago Standard Transformer Corp 30W replacement. The CST Transformer may be original as Fender was in preproduction mode. CST had been shipping transformers since 1939 and had a relationship with Fender. If not original, then it can be replaced with a Triad 7926 Transformer
* Plate Voltage = 390 at bias of 63/67ma (running hot)
* Output = 7.8 volts, 100hz @ 2 ohms = 30.4 watts
* Two tube sockets have been replaced = V1,V2
* Original Astron Filter Capacitors
* Two Orange Capacitor Drops
* One UF Phase Inverter Coupling Capacitor
* Two Signal Capacitors replaced
* One Cathode Capacitor changed
* Some Resistors changed
* Early Groove Tubes, Power Tubes made by Sylvania
* Tubes = 2 x 12AY7, 12AX7, 2 x 6L6, 2 x 5AR4 (should be 5Y3)
* New three pronged power cord
* Work & Repairs Performed by The Amp Lab on 2/25/2011: Full tune-up & evaluation * Change to 3-prong power cord for safety * Trim bias for 32ma-36ma idle current
* The 1954 “5D6” 4x10 Fender Bassman plays fantastically bright & loud with an aggressive bite. Keith Reinegger of The Amp Lab was extremely surprised the Bassman had only a 30w power transformer. It plays very strong. I hope the above information & pictures do it for you.
for more photos, questions, Amp Lab’s contact info, etc.Please help me better understand the USA vintage guitar amplifier market as to:1) Should I fix this amp before I sell it?
It plays great * has three 1954 Jensens * one 1961 Celestion * 2 or 3 original transformers (I believe the 30w power transformer by Chicago Standard Transformer may be original) * most everything else except for a some capacitors seem factory installed. From what I have recently read and uncovered, the 1954 5D6 Bassmans were all hand made and not mass produced. Each 5D6 Bassman amp varied from other 5D6 amps either slightly or in major ways regarding different part variations of tubes, capacitors, transformers, resistors, circuitry layout, etc. I do understand that Fender experimented with different part suppliers and with various inventory on hand (which means that many of the 1954 5D6 Bassmans had different parts and some parts had different specs from amp to amp). I have discovered that serial numbers between 0013-0089 were actually made in December "DL" 1954, but interestingly enough the earlier November "DK" 1954 Bassmans which had a "higher" numbered series 0700-0783 but were made first! Therefore the 0700's were actually the first series made in November and the 0001's were made later in December 1954. I have seen reports of SN #0013 & SN #0035 strongly announcing & claiming to be the earliest serial numbers, but they do not or cannot show their month "DL" chart stamps. 1954 Fender Bassman #0089 has the year/month "DL" on it's tube certificate, meaning my #0769 "DK" is earlier than his #0089!!!! 2) Should I sell this 5D6 Bassman?
Is this a good market? I have known this amp to sound bitingly strong with very good tone. I read that the famous 1959 Fender 5F6-A Bassman amps had the greatest sound/tone, but that the few 1954 5D6 Bassmans are actually better, although only nine 5D6 amps survive. Would a buyer recognize the better playability sound & tone and be willing to pay for it? Does EBay actually do a good job representing vintage amp buyers? Should I list it on a forum or online listing service or Craigslist or OLX.com? What do you think? Has anyone experienced selling vintage amps? What would you do or avoid doing? Are their good sites to list vintage amps for sale?3) Should I restore the amp, keep it and sell it at a later date?
Does the economy play into buyer's actions? Are there Jeff Becks, Brian Setzers, Memphis Bluesmen, Nashville Country Twangers, Rockabilly Blasters, Robert Gordons, Buddy Holly lovers, or vintage amp collectors who would be interested? How can I locate them? Personally, I thought all these years I had a 1955 or 1956 Fender 4x10 Bassman. The Amp Lab in 3/2011 said nothing about it being a 5D6, and he is the one that took many of the pictures including the great shot of the Bassman's birth certificate tube chart record inside the Bassman. Thinking I had a 1955 or a 1956 Fender Bassman, my initial intention was to sell this Bassman for $5,000. Two weeks ago I found out it is rare and was not presented well on EBay. So, here I am seeking any help with your thoughts & comments. Please tell me what you think?
Thank you. Toppscore
During 1977 I purchased a Fender Bassman amp from Leo's Pro Audio in Oakland, CA. I put all my many old Fender amps & guitars into a household storage in 1983 for 28 years. This Spring 2011, I took two of the old Fender amps and two of old Fender guitars to get "professional" tune-ups and paperwork ID recorded. I was going to sell the amps & guitars on EBay. Two weeks ago, the day before listing on EBay, I discovered that my amp is a
