Secrets of the Fender 5E6 Bassman - The Original 1956 Dual Rectifier! Service & Demo

Поділитися
Вставка
  • Опубліковано 15 чер 2017
  • This tweed Bassman amp once belonged to the bass player for Tennessee Ernie Ford of "Sixteen Tons" fame. According to the current owner, he played this amp in Tennessee's band from 1956 until about 1960 or 1961. This is the 5E6 or 5E6A version of the Bassman with two 5U4 rectifiers, 6L6G or 6L6GB output tubes, two 12AY7 and one 12AX7. This example will get a complete overhaul, including all new Sozo NexGen caps and F&T power caps. At the end, we'll demo it with a Les Paul Jr., a Fender Strat, and a Hofner 500/1 Beatle Bass. This is no Mesa Boogie. This is the ORIGINAL "Dual Rectifier"!

    The fact that you thought to swap the ground switch out for the standby switch made me incredibly happy. I usually scoff at people who insist on keeping vintage components, even if they don't work properly, but that was pretty brilliant, and probably wouldn't have even occurred to me. Much respect for your attention to detail.

    Gotta say, this was a GREAT video. Very well explained with deference to the historic nature of this amp. This is the first time someone explained negative feedback in such a simple and clear way. Thanks for taking the time to make this video, show the schematics and document your process (it is much easier just to do the job without documenting so we really appreciate the time taken to share). Great job... Love my 1992 Bassman 59' Reissue but this 56' is truly a rare and special thing.

    I just had my 59 Bassman (that I stumbled into!) serviced after nearly 50 years of storage. We went with Sozo blue caps in it as well to replace the Astrons that were leaking badly. They sound amazing - very similar to this beautiful 56. Interesting side note on my 59 - it spent its entire previous playing life (1959 - 1967) as a bass amp. Thanks for the great video!

    I'm glad to see this was reworked with respect to historical specs. I've seen a number of old amps that have been "hot rod modded"so that they are more modern in function and I always cry a little bit on the inside.
    I think that replacing worn-out parts with new same spec pieces to keep the spirit is great because it keeps the amp in service, the way it should be!
    I really enjoyed watching this video and listening to your explanation of not only what you did but why you did it. The wiring harness debacle was obviously a cluster****! "Who does this?", Classic!
    Great tone once you got finished!

    Looks so much better with the ‘premium’ capacitors you used in this build rather than the usual ones you use. I know there’s no difference in the way they function but they just look so much better in a vintage amp. Excellent job and great video

  • @satanbane
    @satanbane 4 роки тому +1

    That 10M feedback resistor is an important circuit element; it's not just to make the tone cleaner, it has the effect of creating a virtual-ground summing junction at the tube grid, summing together the two input signals. It would prob work acceptably without it, but mathematically a different function is happening and you'd lose the crosstalk and noise rejection of a virtual ground. This is quite analogous to the same inverting summing amplifier realized with an opamp section, which might be more familiar to some folks. All this sophisticated circuit theory was developed well before transistors!

    I'm glad you mentioned the difference in turn on voltage from selenium to silicon. Going from 0.2V from 0.7V turn on voltage doesn't seem like much, but for younger viewers it helps to remember the way the amp was designed. Good video!

    Hello. I used to own one of 'these, I had to sell it in 2011 for money, still regret it. I bought it used in 1983 from someone in Upper Michigan for $100.00! I replaced original speaker with Bassman Reissue ones in 1991. Handle was always broken off, tweed torn at edges a little, grill cover in good shape and front label still there. Wonderful sounding whether using a Strat or Les Paul, using a Tube Screamer or Chandler Tube Driver. Recorded well and sounded great live. So now I'm "settling" for a 100 watt Marshall half-stack and a 2x12 original Marshall Silver Jubilee 50 watt combo.

  • @TheGuitologist

    NOTE: I forgot to resolve the issue of the 10M feedback resistor.... That resistor was not present in this amp and by the look of the solder at the spot on the board it was supposed to reside according to the layout diagram, it never existed in this example. Even though both the 5E6 and 5E6A schematics show it in the amps, it was never installed in this one. Furthermore, even though this is the earlier 5E6 , it had the 3300 ohm resistor in the bias circuit, like the 5E6A, instead of a 6800 ohm as is shown on the 5E6 schematic. This shows Fender was probably tweaking this circuit through the life of the model.

    FK is November 1956. What a cool ass amp! 18ga stranded blue and brown cloth insulated wire would be correct. GB's or 5881's would be great for guitar, GC's for bass. You probably already know that, I'm a Bassman nerd, if you ever have questions about the 5E6(a)or 5F6(a), I'm always around. Milstap has a great video on the 5F6A differences from the schematic of 59 and 60.
    I really should watch the whole video before commenting. The GZ34 was released by Mullard in 58. The 5U4 was the best for the application at the time. The Blue Molded caps are great replacements, as are the Jupiter yellows. The Sozo caps are great after 20-30 hours.
    The PI input cap needs to be .1uf 200v, I don't know why but it sounds better. Charge time? Plate specs? Who knows why. Jupiter makes the yellow type .1uf 200v.

    By the way, as an EE having worked on technology from DC to over 100 GHz (defense and such), I am impressed with your practical presentation of information that is very informative and boils down your experience in a succinct and interesting way. Having done the theory, you have improved my practical design and tweaking skills in a very esoteric field of audio that requires a real understanding of the practical application and history of the industry. You distill the the technical and subjective attraction to vintage gear that has collectively evolved for decades. Keep up the good work!

    amp sounds fantastic! and your latest venture in recording better for the channel seems to be paying dividends sir. :)

    • @TheGuitologist

      Thanks. I have decided to just use the onboard cam mic for all the desk stuff because of the risk of an overhead falling into the amps and because of the 48V phamtom power which would require me to move my mixer setup back and forth across the room. But the demo part is getting better. I'm still going to be tweaking on it a bit and getting the mix between voice and amp a little closer in volume without anything clipping. It's a balancing act.

    You're a damn good bassist, mate. Would be great to hear more bass from you in future.

    • @TheGuitologist

      And here I thought I sucked. I'm not fond of my bass playing. I have recorded bass tracks in the past and I can make it sound ok given some time to practice, but it's far from a natural thing.

    Rare amp and cool video, thanks for sharing it. I agree with most decisions made on the "service" (rebuild might be a more appropriate word there) with exception to the changes in the preamp circuit including; the resistor removal, the different value capacitor and the preamp tube substitution. Taking those liberties with Leo's design completely changed the character, not to mention the resale value of that amplifier... I'm just sayin

    I have been interested in electronics my entire life and have always been an audiophile. I have learned so much from your videos and am even more interested in repairs than ever before. I am currently working on an old Arvin 760T AM radio, I guess that I am starting small. Great instruction and adding interesting comparisons and observations, you sir are an electronics jedi. Thank you again for sharing your knowledge and talents.

    Hi Brad, love the videos.
    I've just swapped a speaker over and did something I always do, and just realised that I have done this for years, casually touched the soldering iron with the tips of my fingers to make sure it's not still hot before putting it away...... After all, you can't be too careful.
    Safety first eh....? LOFL

    Pro harmonica player, 45 yrs. I've had about 10 original Bassmans, in the G(1957 serial# 0017, the "-A" on 5F6-A hand written on), H ('58), I, J 1960 years. Currently an April 1959. They are great for harp BUT, always have guitars players plug in for a spin at gigs. Any guitar sounds great but, wow on a Strat into a Bassman. Beautiful amp, nice tech work too.

    Thank sweet Jesus you know how to mic an amp for the demo. There's so many people on UA-cam showing cool stuff, and you get to hear it from a mobile phone's microphone. Can't judge any quality.

    Hi. First off I subscribed to your channel about a month ago and it has quickly become my favorite channel. This amp sounds incredible especially playing that Gibson with the P90 thru it. On a side note I have an early Marshall JCM2000/DSL100 with an issue which initially brought me to your channel to begin with hoping I could find a solution. I believe you have a couple videos on those particular heads. Took it to a local repair guy here in town and he couldn't fix it. So not sure what to do about it. Not playing out these days so don't really need it just want it working properly. BTW you're an excellent player!!

    • @TheGuitologist
      @TheGuitologist  7 років тому

      Thanks. Do the tubes glow? Make any noise at all?

    • @jbl5050
      @jbl5050 7 років тому

      Thanks so much for the quick reply. The amp actually works and sounds normal but after about 15-20 minutes it starts humming rather loudly. I was hoping it might have just been a tube issue but the guy who looked at said he swapped out all tubes one at a time and it still did it. I could record a short video of it acting up for you if might have a few minutes to look at it. Thanks again!!

    Great video! You took the legendary Amp, that did not work, fixed it and made it a touch better. All totally reversible to the Stack configuration. Nothing to feel bad about that’s for sure!

    Good move on changing out those IC filters with F&T's ... As a guitarist of 58 years, I would prefer the SoZos, especially over the orange drops. Put in what will last the longest and not fail in four or five years while a man is playing a job. Beautiful amp. The dual rectifiers are most cool. Thanks for putting this up.

  • @johnnyfeagan3103
    @johnnyfeagan3103 4 роки тому

    The long tail inverter is the legacy of Marshall and so many others...I think the cathodine Fenders compress so different. Ampeg took this to the bank. If you want to see something totally different go to improved paraphase inverters, the sound of the D Fenders is incredible, I usually only build the Western Electric circuits from before 1957, these amps have a tone that is unlike anything else, and they are loud. Thanks for all the great information.
