Fender Silver Face Twin Reverb - Part 2

- Here I get stuck into the nitty gritty of cleaning up this poor old bugger.
I aim to make it a bulletproof beast as it's a backline and studio workhorse.
I also to aim to make it the best sounding Twin in town.
Note that there are some component values shown on video which are not the final values, either intentionally to keep some cards up my sleeve, or as a result of the video being shot before final voicing and finetuning has taken place.

Hey Brad, your ocd getting the better of you is what separates you, Lyle, and a few other techs from the herd of hacks. You adhere to a level of excellence, which is unfortunately no longer "the standard". You are a champion, my friend.
What an absolute mess. Great work getting those boards clean.
Every Good Mudhoney deserves F… nothing less than this level of care and attention to detail. Amen.
"I will leave what I feel comfortable with" then completly rebuilds the amp. You sir are a real champion. Hopefully the next tech who looks at it in 50 years knows that a real tech worked on it last.
Yeah, that board was absolutely filthy. Spare no expense! 😆
Excellent, those Fender amplifiers are built like tanks!
In 1976 I purchased a brand new Twin Reverb, all these years later I still have it and play it regularly.
As far as I'm concerned, it was the best $400 I've ever spent!
This is Uncle Doug on steroids! Brilliant video. Subscribed and off to watch the other parts! Made my soggy Saturday a bright day!
Glad to see the cathode bypass caps find their way to the fuckit bucket. The clock starts fresh on all the electrolytics now. Orange drops are good caps but they look a bit clunky even on boards where the spacing has their leads going straight down. If the span is wider, they look downright fugly.
The price of this job went way up but I predict when the customer sees this video, he'll get a woodie and be glad you went this way.
Brad, you are showing us what impeccable work looks like.
Something I _never_ get the chance to see.
Thank you for the time and effort you put in, to share with all of us.
Shipwright's disease got you on this one.
A job done the right way!!
I love watching your work. Your OCD helps my OCD : )
I simply KNEW you'd do a full rebuild when you let on how much you liked Mudhoney! Great work as usual, never calculate your $/hr IMHO.
Huge amount of work needed to clean up that filthy eyelet board!
I hope you will receive sufficient financial compensation for all the work you have done.
Wow. Brad... I love the new look of your videos!
Glad that I can use this comment to justify all the cameras and lenses I own!
Very impressive job man! That was in such a disgusting state.
Beauty work mate.
Where ya been buddy? I was worried about you
Part II delivered, great work Brad. Looking forward to the next upload, thanks for the quality uploads!
The customer might 'wince' at the cost of a rebuild as meticulous as you're doing, but in five yeas time when he hasn't had a breakdown or paid for another repair, he, (or she), will look back and realise that you get what you pay for. What your doing is the 'right' way to do the work on a fifty year old classic amp in order to make it reliable and work to it's original spec.
This has nothing to do with OCD. This is doing a proper job to ensure the amp will be reliable for years and even decades to come.
This has motivated me to fully tear down my dad’s old Bandmaster, god help me. I’m already taking a lot of stuff off of it to redo some mods done poorly a long time ago, so why not go all in. At least in my case no one needs the amp for a tour so I don’t have to pull any all-nighters. 🙂
Maybe just wait until my advice in the next vid, mate.
Unless of course it's a hobby, then the longer it takes = the better!
Outstanding as usual, mate. Great video and what a beast she is.
I was wondering if/when the OCD would dictate a more in-depth approach. I feel your pain sir. Great as always
they completely botched the ruler mod, metric ruler on a fender amp is never gonna sound right
I know, right!?
Although, in this day and age, with all the magazine reviews, we know now that Furlong based rulers sound the best!
I fully agree. In addition, the colour of that "dielectric material" did not fit at all.
Lovely job mate.
Really nice work on that board man.
Nicely done! You are the champion, Brad ☺. I was fixing to do this procedure on my '73 silver face twin for some time due to leakages, but I lived on Fort Myers Beach and hurricane Ian put a stop to that in September 2022. My residence collapsed under 16-18ft of water and that amp is now swimming with the fishies. Watching your video maybe I should appreciate that fate.
Oh man, so sorry to hear that.
Looks like a beautiful place to live, but being at the mercy of mother nature is a bittersweet existence.
@@BradsGuitarGarage , the highest ground in Florida is only about 9 feet above sea level. There are no safe places to build. Fort Lauderdale just got almost 2' of rain and is having major flooding: and the land is so flat that there's really no place for the water to drain off quickly. Floods are always the most dangerous type of natural disaster; no offense meant to FL residents, but I wouldn't live there.
Meanwhile, up here in New England we look like we are setting up to have another drought, like we did last year. I live up high on a ridge, and so there's absolutely no chance of flooding here anyway, no matter how much rain we might get. I do, however, worry about forest fires around the 4th of July when people set off fireworks....
After 3 years of LaNina, we're headed for a "Super ElNino" according to the bureau of meteorology's long term forecast. Normally we have at least 3-5 neutral years between.
The outlook does not look good.
We'll have unprecedented fires, much worse than 2019 if that's fathomable, by the end of the year I dare say.

@@BradsGuitarGarage Yes, as you might imagine I do follow these trends closely. It will be better for us on the west coast of Florida, but I feel for you guys down under. That was horrible. Whereabouts are you down there?
Western Sydney.
At the foot of The Blue Mountains.
Wow... If it didn't cost an arm and a leg to ship my twin to you....
You’re returning the ruler in the bag of parts that go back to the customer, right?
Of course!
How expensive are these boards and are the readily available? Seems like it'd be cheaper.
OK, OK, I would have stripped the boards and started all over, too.
Awesome work Brad. I hope the owner of that silverface appreciates the time and effort required for this clean and re-wire. The ruler got me laughing too. Is there precedent for a spacer between wax eyelet boards in any instance? What would be used normally?
The spacer board (referred to as "insulator" in the video) is a board with no components, installed between the board with components and the chassis.
That is it's only job.
Given the solder quality the ruler may be used as an insulator . A fine bit of kit ( sarcasm). Well a fine example of Thomas' English muffin school board population .
Why a ruler??? Well that went to pot fast. My ocd drives me mad too and I would need to clean the shit off the boards. Once its been rebuilt you know for sure its safe and works as intended. great update 2x👍
I wonder if body-shop wax and grease remover would be helpful ?
Naptha (know in Australia as "Shellite") is the name of the game there, mate.
Brad, when I purchase my Bassman AB165 you are definitely the person I wish to have restore it! How crazy do you think shipping of the chassis from the US, to you and back again would be?
I have many contacts in the US that would do a better job than I could ever hope to do on your amp, Rob. Shoot me an email and we can see who's closest. Lead times TBC.
@@BradsGuitarGarage Thanks Brad. I will be sure to consult with you when the time comes. I still think it would be cool to own an amp you worked on, as long as the cost of shipping isn't greater than your fees ;-)
Are the boards made with asbestos??
No, it's pressboard.
It would be easier and cheaper to put in an new board with all new components.
The removal, depopulation, repopulation and reinstallation of the eyelet board is the time suck. The cleaning of the stripped board is trivial.
