- Another great Fender amp comes across the bench at D-lab Electronics. This one is in perfect condition, no mods. Has been in a closet for over 40 years. The owner made the choice to send it to me for evaluation. Needed the typical cap job. Made a minor gain adjustment, and bam! Fender Chime was reborn! What a great sounding Class A amp. I really love the engineering that Fender did back in the day. What a great time in life! Wish I was there.
After finally getting around to it, I did the modifications that you described, changing the Grid resistor to 560 K, and the plate Resistors to 220 K.
YES! "Born On the Bayou" with the Tony touch! Sounds much "bigger" than a Fender Champ now.
Wow, you've made that amp come to life Terry.... well done... It's easy to tell when an amp is singing nicely just by looking at Tony's face... awesome brother.
Great stuff! Thanks for sharing your info on raising the gain to preferred levels! I mention your channel every time I get a chance. Good luck on 100k !
You really do a nice job with the mods and the presentation.
Terry, You have obviously done your magic on the tremolo, Great sound!!
Great sounding mods Terry, thank you for sharing.
The tips on the change in plate resistors is just what the novice needs to here, anyone with a soldering iron can make that change. Thanks
Excellent as usual Terry. My vibro champ has been running the 6v6 hot. You've just told me why. Great info. You are quite the tube guru.
Great video! Thanks for sharing some more tips and tricks. I’ll probably watch this again with the schematic to better learn the “why” behind the modifications made. Really cool stuff
I was there! My first amp was borrowed from a wealthy friend, a 1964ish Fender Pro Reverb.. dual 12". After moving, and having to return the Pro to its owner and his vast collection of Fender amps, I found my own Fender, last run of Blackface, Vibrolux Reverb. We knew these were good amps back in the day, but had no clue that they would become legendary. The Blackfaces and early Silverfaces remain among the best amp line ever made in mass production. Nice to see you fixing this gem up. The gain mod is a great tip. 100K is a little low for a 12AX7A. YES much better to use above 200K plate R on 12AX7A to get more gain.
sounds awesome Terry.
Excited now to do these mods and upgrades on my '79 VC, which has always underwhelmed me with its blah tone. Thanks so much for posting!
Another great job by Terry , Marsha the bartender and guitar by Tony........I"m really surprised that you don't have 100K+ subscribers. . .great tutorials !
Hey Terry, I have been playing the modified Vibro Champ daily for two weeks now and it sounds amazing. Great job on the mods and excellent video! Kevin J
Completed all the mods on my '79 VC today, and I can attest that this video is 100% as advertised! Wow! Couldn't be happier with the new-found chime! And if you've never played through one before, it also has the best tremolo circuit Fender ever designed. Telecaster master, Jim Campilongo, will attest to that. Thank you much, Terry!
The best sounding Champ I ever heard
Cant wait to use this on my champ. Well done
Nice fix Terry..Great sound, from Tony's picking..love it..Ed..UK 😁
All the wishes for the 100k subs Terry, you deserve it! How about something on a small tube bass amp design?
