My guess is a lot of people like me after watching your works are buying Fender amps. Because you're showing how to prevent obvious damage. I just pulled the trigger on a Jr and it's going straight to the tech to change caps, raise resistors, etc. Thanks for sharing your knowledge, it's priceless.
Try seating in the expensive seats at the Cincinnati Music Hall and hear the bad bearing in the air handler at a very low frequency of modulation during a performance . The tickets where a gift still. The training of listening can be a curse.
I have found that the amount of current Fender calculated for this vintage HR Deluxe that was necessary to make a stiff brute force zener + and - 15v supply was way more than it needed to be given the load on those 2 supplies.
Man listening to you sought out boxes is a neat learning curve. That Blues Deluxe though has not been loved or even cleaned so things are bound to fail.
Excellent video, have wondered about my DRRI with a similar pulse in the sustains. F&T caps but didn't think they needed changing as they're only 8 years old - time for some replacements! Much appreciated.
Ha ha most entertaining! Hey that was a gem. I've not heard any other tech talk about rhythmic patterns in hum, hiss and note decay. Could you do an aural diagnostic symptom special sometime as an all in one place reference tool for us all. All your favourites, motorboating, water rushing, AM interference..
The story i heard from a few engineers when i worked at Echostar was that the Taiwanese manufacturers were trying to obtain (steal) the formula for the electrolyte from the Japanese.
Even in this day and age of digitally-generated sounds, doctor's offices typically still use a mechanical, analog (?) sound-masking device consisting of a small fan in a slotted plastic housing; you can twist the two-piece housing to change the pitch and amplitude of the white noise. I forget what they're called or who makes them but Fran Blanche investigated one of them a while ago on her "FranLab" RU-vid channel.
Si if your volume is turned up halfway. And you strum and it suddenly just cut off all sound and few seconds later. The sound pops buck on . What could be wrong? It's a line 6 solid state amp 150w
I have a 2007 Blues Deluxe Reissue. I put a 12au7 in V3 phase inverter; calmed the amp,changed the tonal character and sounds great!!! I Tried 12At7 in v3 and it sounded thin so took it out.
