- I replaced a well-used 6-year-old set of tubes that were scratchy and noisy on this Fender Blues Deluxe Amplifier.

Great stuff, clear-concise- and easy to understand because you explain the proceedure calmly and without nonsense. Thankyou.
Great job. Very helpful, easy to follow, you nailed it
You made it look easy..ill have to try myself next time i need to replace tubes.
Next time, slightly loosen the screws on the sides of the cabinet; they compress the wood of the back cover. That way you don't risk breaking the back cover at the thin bits next to the cutouts...
After watching this video I struggled for 5 minutes to get a reading on my multimeter. Turns out I forgot to flip the standby switch. Suffice to say your instructions were extremely helpful (more so if I'd followed them on time!)
wow.....
This is a great video.
Crystal clear instructions and direction.
Quick question,
I still didn't feel comfortable using the test point so I decided to use a socket probe on one of the power tubes and adjusted to a reading of 30mA.
Not sure if this is the same idea but the amp seems and sounds OK.
Bias at 72mv sound best and keep the output transformer runing colder,with better heat disipation for my experience
Merci pour cette vidéo ! Cela ne semble pas si compliqué finalement. Un grand merci.
J’ai cependant une question : comment savez-vous que chaque tube a besoin de 30mV ? Où avez vous eu cette information ??? Tous les tubes 6L6 ont besoin de 30mV ou il faut mesurer ça quelque part ?? Pouvez-vous l’expliquer s’il vous plaît. Merci. 🙏
Thanks for this - from what you saw when changing the tubes, in terms of access do you think it is possible to change the speaker by only removing the back cover? Advice would be much appreciated.
Wow that was surely noisy. I have a Blues Deluxe from ‘93 and it gets regular use and it’s never been that noisy. It just doesn’t sound so good tone wise after awhile so I need to replace the tubes every 2 years or so. Matched tube pairs for certain and look around for decent stock. Some of this stuff looks a bit different in the back of the reissue but mostly the same. Do you have any experience with the 90’s models? This was an informative video, thanks.
Great demo. What is the name of that tool you used?
Great video ! Thank you. Can I ask you some questions? I have matsushita 17ew8 tubes. Can I use 17ew8 to guitar amps or guitar effector?
Sorry, I don’t know the answer to that. You may need to look to an amp technician for that information.
Just curious, dielectric grease, not recommended?
i'm curious did what did the amp sound like after the tube change? Did it fix the noise issue?
Yes, changing the tubes immediately cleaned up the noise.
Thanks very instructive ! How often do you change the tubes ?
This is the first time I’ve changed them in this amp. Tube age isn’t the best indicator of an issue, so it was mostly a matter of sound quality than a matter of time.
How did you determine the bias specs?
I looked up a service manual online and it said these were the specs.
@@TechStuff1 Thx!
Tapping the tubes is ok but when the amplifier has a great signal from the guitar it is hrrr. no matter with or without preamp
Hi i got 0mv why?
When i set standby on in max position is 40mV more or les
Then??
Please dont use the cordless drill/screwdriver for mounting the screws. You risk ripping the threads. Dont do it!
throw that global bs cage away
Those Chinese 12ax7s are garbage..
