Hi Chris, stumbled across your website and vid. Love seeing a guy passionate about his craft! Thanks for sharing the vid. Nice for the average guitarist to get a tour of the inner workings of a tube amp 😊
Thanks for all the answers the other day. but a bit over my head on things. The question I was trying to ask is do you have to worry about Cross over Distortion as much if a set of 6V6s or 6L6s in push pull mode are Cathode biased at near max plate dissipation? Please explain in layman's terms. I'm simple that way. Please and thank you. Dwight. Again your work is very well with excellence. I like to brake things down into simpler terms. It helps me understand things better. I really love tube valve electronics in radio or guitar amps.
Aha! Now I understand Dwight. You are much less likely to see crossover distortion (COD) in a cathode-biased power section. You usually see COD when an amp is biased too cold where one power tube is turning off before the other is turning on, often with less than 50% of maximum dissipation. As a cathode-biased amp is usually well biased at 90 to 105% it is improbable it will experience COD.
@@theguitaramptech Ok Chris thanks again. I figured that as much since cathode biasing Causes the tubes to amplify the whole since wave cycles. Iv heard that it is called class A push pull. Dwight.
I'm not sure if I completely understand your comment, Dwight. Push-Pull commonly refers to Class AB amps, where one side "pushes" and the other "pulls". Even Vox amps operate in Class AB as well as Class A depending on the volume setting.

I'm a newbie and following various amp techs to gain as much info as possible on amp repair etc..Great video, and repair..!Thank you for sharing your knowledge..Ed..U.K...😊
Edward Hannigan. Thank you for your comments Ed. I’d say the best “teacher” on RUclips is Uncle Doug. If you haven’t found him, definitely look him up. I show my support through Patreon. Ultimately, you’ll need to gain knowledge through private study. I did Elec Eng at uni, and 40 years later, I still invest in my learning. I reckon you’d run screaming if your surgeon said “relax. I learned my craft in YT!” LOL! 😂 Enjoy your journey, Ed.
@@theguitaramptech Hiya, thanks for your reply, much appreciated and the info about your experience and knowledge. I have already found Doug, and he's just fabulous. You guys are awesome..!😀 Ed..U.K.
Gee. In all honesty I can't remember. I think so, but please don't make me watch it again. I enjoy making the videos, but by the time I have finished editing, I am well over me!
7:06 was screaming at my screen "NO, CHANGE THAT V5 POWER TUBE SOCKET!!!" But then I calmed down and remembered that pin 6 isn't connected to anything.
Sorry, I'm not sure I got your point. Are you referring to the screen resistor going from pin 6 to pin 4? Yes, its a convenient and secure place to make the connection. As you say there's no connection on pin 6.
60 watts, holy smokes! Are they supposed to be that powerful? A Vox AC30 l don’t believe is putting out a true 30 watts clean before clipping. And this amp is double that ? Goodbye hearing. These amps were built in the old days with huge stages, very little P/A and 50-100 foot long guitar cords so you could stand a comfortable distance away

"The final standby", and... trumpets! Or is it synthesizers?😊
Have just stumbled across your vids, really great stuff to watch and listen to the walk through. Quite an education in many ways. Thank you... :)
Thank you for your kind words, Peter. I'm very happy that you are getting value from the videos

Is this the 6G6B circuit? Great work, sounds awesome.

@@theguitaramptech No worries, I was referring to what looked like a spot of carbon on the face of the old tube socket on V5.
@@MuscleDad420 Thanks for that
Even your guitar playin is hot.
ou are too kind, Dwight

Haha. Loud. Beautiful loud. It’s almost “ a Loud” worth losing a smidge of hearing for. 😉
