THANK YOU! That towel tip while soldering speakers and testing the input for the total ohms just blew my mind (it get's blown pretty easily). I am currently working on a 2x10 amp and I greatly appreciate those tips.
Thank you for your great work, teaching, warnings, savings and advice!❤ you’re the first I seen to do SRV MODS, by Diaz, if there’s more videos on it are you able to link their sites or RUclips….
I was curious if you ended up replacing the reverb tank? If so, how were the results? The one in the sound sample seemed to be super sensitive and splashy. Wonderful amp though!
Hot goes from the wall to the fuse to the switch to the transformer. Neutral goes straight to the transformer. if you want to use the death cap, it goes between neutral and chassis and it might help get rid of some of the RF crap that comes into the amp through the AC, particularly when you are in a BAR setting and on the same power as the KITCHEN or the dimmable lights. SCR dimmers are well known for causing a lot of noise on the AC. Chances are good in those situations your single coil guitar pickups are going to be more angry thhan the amp.
What is odd to me, and I can’t see the back, but normally on the neutral the screw is shiny, and the hot screw is brassy. Yours appears to be the opposite. I didn’t think the outlet was polarized at all on these.
Thanks! I'm building an AP1 conversion at the moment and I see you signed up for in stock alerts which is the right thing to do 😬 you will be notified as soon as I am done. I will make a few more as well in an alternate enclosure or a customer can send me a donor MK2 enclosure for retrofitting. ⚡
There is a lot of stuff different in there. I’m not sure if I would change the ceramic coupling cap between the V4B and the PI to a film cap. HA HA, its the first one you pulled out. In any case, that shouldn’t be an OD either. I’ve never seen one with an OD there. All the sound of the amp goes through that 1 ceramic cap.
I would probably make the ground wire slightly LONGER than the hot and neutral so if the wires ever got yanked right out the back, and ripped the wires off, the ground woudl be the last one to rip out. Really nice work.
Wow!! your friend is a nice guy! Now the board flex is normal for the age of amplifier but the ground wire not soldered is crazy and too short - it should be double the length of the hot and neutral.
Not too much at all! In fact, it can be pretty easy to do! My only hesitation is this is not the right amp for that mod. I'll do it on my personal build one day 😉
TONE GEEK, Cesar Diaz replaced the output transformer with a 50's tweed twin output transformer because it had a different midrange growl and more headroom cleaner before breaking up. Why not make a video lesson about this seeing this on the oscilloscope the differences in output transformers?
You deserve it or it would not be so..... I need a good Tube amp.... I was hoping to run up on a similar situation...or maybe a barter or trade type thing.... I have a couple of Road bikes I would trade... One a Specialized Carbon fiber.... One An old Motobecan Both super nice.....
Lucky guy, best fender amp ever made. I would try to keep it original.
Thanks!!! It's truly an amazing amp
nice looking work, that's a clean looking amp

So happy!!! Thank you for your feedback!! And thank you for watching in detail!
Very very cool!

Those phase inverter coupling caps are usually swapped out because they 400v. The Mallory’s are 630v.
Makes sense! So they are on the very edge of their design
@@TheToneGeek exactly, especially with wall voltages often being up in the 125v range as opposed to 115v.
The Mallory 150's are also a polyester cap. I actually prefer them to the Sprague, tone wise.
@@johnmarshall3903 interesting about the choice and also right on about the poly. I should have mentioned
Have a 67 love it and a Pro Reverb 66 Hard to say which is best.

Very cool. Love SRV and Cesar’s mods. Was wondering if you were doing another run of your lomark pedal or fully complete aqua conversion pedals?

I think replacing plate loads with METAL FILM 2W are fine cause it really reduced the NOISE of the amp. Some folks like the sound of hiss.

Why not just footswitch in between Vibrato and Normal channels rather than add the pot for the trem?
Where do you get these orange backed switch pots? Mine are black.
2 of these running dual mono or IIrc ?
Would it be too much to add in your amp rectifier board and make it switchable to tube rectifier?

That's an awesome idea! Thank you! Exactly why I read the comments lol
@@TheToneGeek @wayne Gram Call up Mercury Magnetics!!!
@@TheToneGeek yes!❤
show the world the world the Diaz Mods for SRV!❤️
this is the first I have heard of the Diaz/srv mods on utube…!!!
Wait, do orange drop capacitors have polarity?
There's a shield around them which is theoretically where the low impedance side should connect to
You are an amp butcher. What you did was horrible? I feel so bad for the amplifier.
My car says hello to your car.

☹️ 'promo sm'
It's obvious that you don't know anything about these amps and SHOULD NOT BE TOUCHING IT!
