  • This video features a beautifully built Victoria clone of the rare and wonderful Fender 5F4 Tweed Super Amp. The owner complained of "fizziness", fluctuation of volume, and possible red-plating of one tube. Join us as we undergo a very cautious, methodical elimination of all possible issues and arrive at a (hopefully) satisfactory resolution. We also install an 8 Ohm speaker output jack and a switchable NFB Loop. In addition we will open a fabulous gift from a generous viewer, check in on Mitzi, the voracious feral kitten, and get some tree pruning tips from an obviously skilled neighbor.

    As an ex-navy ET (electronics tech) you bring back memories of instructors I had explaining tube behavior and circuitry. Now in my early seventies, I just finished rehabbing my 1960’s Magnatone M-15 during Covid days. Your vids gave me a lot of suggestions and ideas for trouble shooting various issues. Great stuff. Thanks.

    I built that 5F4 tweed Fender Super clone from Mojotone kit. I'm a fan of class 'A' phase-inverters. I made a few mods: used a 5AR4, added an additional 47uF cap to the power supply, added a bias control potentiometer, rewired the choke coil to feed only the 12AX7 tubes; which increased the power output, installed a 50 watt output transformer. Great fairly lightweight 35-40 watt amp. :)

    Hey Uncle Doug, I built my first amp last year from a marshall 20W kit. I just followed the instructions and it worked at the first try. Before starting the build i had no experience in electronics, and id been reading about safety and circuits for a couple months. So i wanted to understand how the circuit actually works. And then i found your channel on youtube. I know you hear this all the time but i wanted to thank you for the best instructional videos out there. The way you explain things makes it so easy to understand. Your channel is a national treasure! Im now getting ready to build a fender champ all from scrapped parts from old radios and reel to reel recorders, very much like your video. So again thank you for being the best teacher out there!!

    Hi UD, nice video. One note to mention, I have the Fender Super Amp, and I changed the rectifier to a 5u4 from a gz34. A customer brought in the exact same amp as mine with a gz34 rectifier in it. An A/B comparison revealed quite a difference in gain. I didn't check the bias comparison, but if your customer changes the rectifier tube to a gz34, I am sure a re-bias is advised to cool down the 5881 tubes. Great video as always Uncle Doug 👍.

    Another masterpiece theater installment, thank you Doug! That amp sounds absolutely wonderful. I have been trying to purchase those Eurotubes bias meters ever since you demoed them a few moons back and they are still sold out! Very much hoping they return to market some day, being a much safer alternative to the shunting method that gives this particular amateur the heebies.

    Hi Uncle Doug. I hope all is well.
    The craftsmanship of the Victoria is amazing. The word "symmetry" come to mind when looking at he layout.
    I'm still a rookie with an opinion that's worth exactly what it cost and but agree that the 7581's were incorrect, and I suspect the fizzy and unstable output you could not reproduce was caused by the tubes being starved with a cold bias. As strong as they are it would seem logical that without adequate power they would never be able to stand up and sing as intended.
    The Ford grille shot and Mitzi bathing herself after dinner were an added bonus to an already excellent video. Thank you so much.

    Another great video from Uncle Doug. One thing that should be noted regarding the kill switch on the feedback circuit. IF there's a Fender presence control, opening the feedback loop takes the presence control out of circuit as that control is part of the feedback loop. FYI.

    Hello again, Doug, with another excellent video, amp, and...what a gift!. I am searching for one of these cap testers for ages!. It seems to be difficult from here in Spain. And also: be very careful with the tester, because it outputs as much as 600 dc volts in the banana jacks. Never forget to discharge it, and put the test voltage knob at its minimum, because we need to see your videos during too many years! 8-) Thanks a lot, and God bless you, Doug & the cat gang.

    You always do a very nice job on your videos, and it helps a lot of people wanting to learn about amp repairs. On the speaker jacks however, the output transformer should always have a load on them when nothing is plugged into the jacks. This is why Fender always shorted the speaker jack when nothing was plugged into it. The reason being is if someone should plug a guitar into the amp without a load and then play the guitar the impedance of the output transformer will go sky-high. This can create large voltages and can cause the 6L6 tubes to internally short or cause the tube socket to arc over due to the excess hi-voltage across it. There should always be some kind of load on a tube amp to control the output transformers kick-back voltage.

    The presence on the 5F4 is pretty enimic. Also it should be noted that when turning off the NFB loop, it will render the presence control inop.. but not sure it would matter that much as it is pretty useless. I placed a .47u Cap in place of the .1u on my presence control and it made a difference, at least you can tell it is actually doing something now. Great work as always Uncle Doug and we learned of yet another 6L6 variant.

    That Heathkit is a jewel! It's younger than my piece of Heathkit test equipment - I was given a Heathkit AQ-1 audio signal generator (circa 1957) by an old neighbor - and after a set of electrolytics, it's as solid as a rock (if you don't mind the analog frequency dial!) The head technician had a Heath cap checker similar to yours at one of the shops I worked for, and if he suspected a tech of shotgunning caps, he'd take it from the margarine tub and test it while the tech was away, then leave it on his bench with the results scribbled on a piece of paper. Needless to say, we mortals dare not step into his sanctum to test our own caps but he would break it out sometimes if we were stumped and he suspected leakage that we had missed. I wonder if someone has written a book about the whole Heathkit phenomonon - a real example of post war GI industriousness and excitement about the hi-fi craze. One thing I remember about Heathkits - when the owner was stumped by a problem, he'd bring his unit in with all of the encyclopedic manual, notes and records, and go over all of his prior troubleshooting in detail! I can't wait to see your future comparison video with the current magic box digital cap checkers. I use them, but don't completely trust them (how can a $15 ebay cap checker do the same job as the $450 B&K? circa 1975). Thanks for the great video, as usual!

    Hello Uncle Doug . Another great video and a nice amp. .The layout is very neat, i sure you were pleased to see it. It ressembles your own builds. Victoria is a very respectable brand. They are known for their vintage Fender inspired/cloned amps. But they also did a series of amps for Gretsch wich are very good. In the 00' i think. "Playboy" and perhaps other name models. A friend of mine who is a pro player have one and says that it is his number one amp.
    You talk a little about the "presence" control. In fact this control is very akin to your NFB switch mod. When up the "presence" control sends high frequencies in the NFB loop to ground and then 'switch' off NFB for this frequencies. When the NFB is switch off the "presence" control is defeated. It is very different than a pre-amp filter, unlike the "bass" and "treble" controls, as it controls the power amp behaviour . It may be very interactive with other controls, thats why people didn't always understand well what it do. I don't mean to learn you that but it may be a topic for you to discuss. I'm sure it would be very interesting, even for me.
