Thanks D-lab, at college our teacher used to call it an "Occular Survey" using the eyes to sus out the circuit. He actually learned his craft just after the 2nd WW and in later life became a teacher, I salute you and him for being excellent teachers.
Thank you my friend
@@d-labelectronics Credit where Credit is due.
I love it! "Look for burned parts" is my tube amp motto!. I also don't care for solid wire in these as they break. Bravo Terry!
Thanks! D-Lab🔌
As a owner of '72 red plating twin reverb, thanks. Me and my fender, univoh amps are getting older and this days is hard to find solutions for our ilness 😀
Great video!!! The troubleshooting phase is where good techs earn their money and keep wasted time to a minimum. That one probably would have had me stumped for a while!
Terry, Merry Christmas to you and your family.
Freakn love the sense of humor !!!!
I really like your shirt.I also really like the probe you made its a great idea especially for these old amps.
I'd love to see the whole process until the end. I understand you show the analysis and method to discover issues but... a couple of minutes more with you soldering the wires and components would be more interesting
A Twinsted Web indeed. Merry Christmas To you and yours D-Lab!
LOL Broken Arrow. That takes me back 40+ years. BTW - I enjoy your diagnostic approach.
Great Video Terry..Thanks for sharing, always something new to learn..Take care and Happy Xmas to you and your family..ED..uk..😀
+++an old german trubleshooting- rule says : *** the Devil is a Squirrel*** i hope that can be translated like that+++ thank you so much ,Master
Love this basic training series !! Very helpful to see the thought process for finding faults in these amps. Thanks for these
Merry Christmas Terry! Thanks for the entertainment.
Nice find sherlock...
Thank you D-Lab
Thanks 👍
Excellent Terry.
Thank you so very much, for the time you take teaching someone like me!!!
no- no go dlab were out here watchin were weird people who watched when you went to that swap meet thx
its good bro happy honickerxman
Very nice video.
And that's why as well the g1 contact of the tube socket must always be clean and tight. If it is dirty, oxidated or loose, causing negative bias voltage not being present at grid1, it causes the same unpleasant result to the totally innocent output tube as the broken wire did.
Wow, thanks, so always clean and tighten the sockets,right?
Great video. Thanks Terry
I had a Leslie amp which had no continuity from the cathode resistor to ground. Visual inspection showed the solder connections of said wire were secure.
It turned out that the ground wire was broken INSIDE the insulation.
Merry Christmas Terry!
Thank you for all the great content. See you in the new year…🎉🍷🍷
Merry christmas
Nice catch, had me fooled!
What kind of mod was added with the pot in the input jack? Are you planning on putting back to stock in a future video so share with us? Thanks for all you do to make these videos Terry.
Yep, already pulled that mod and reinstalled a 1/4" jack. Amp is close to test time
Mind-BOGLE’ing indeed! 😁
Enjoy this series a lot, keep it up!
Thanks Terry, instructive and entertaining 😀
HAPPY NEW YEAR !!! 🍀🍀🍀
Nice model sir

Happy Christmas to you and and your family

Its a 10! Because there's vino on the workdesk :)
Fantastic !!! 🙂
Good one!
wow so epic !! 🔥🔥
Hey Terry, I have a clone blackface twin reverb. Made in the Philippines in the late 60's. The switches for reverb and tremolo we're hard wired to the chassis. No plugs. I was wondering if it was possible to put in toggle switches in the rear of the amp instead of floor switch plugs. Right now there are no switching functions.

Maybe the assembly person ringed the wire with their strippers back in the day, and it took 40 years to snap. I could see how this could happen, having worked in a factory panel shop doing point to point wiring.
Was the associated 470 screen resistor still ok ?
Nicely done!
I can logically deduce that mouse had something to do with that poor connection, he was sniffing around very suspiciously.
Also to keep in mind guys china and Russian tube pins are thinner on American sockets so the connection is poor that’s why I don’t use them and there junk anyways
Nothing for the shoulder?
