Helped my friend with some tube swapping in his new amp

Hello all,

My buddy handwired (First time!) a little 5w Fender tweed amp. He is an older guy who is experienced in electronics repair and all of that jazz. The amp has 2 inputs and a volume control. THAT'S IT. He hand built a little cabinet for it and, very heavily influenced by myself, and outside of his normal nature, he covered it with an 'iridescent snake skin' tolex. It looks wonderful. Very 'Custom' looking. Onward to the events:

I have been a ton of tube rolling in my Rivera Cliubster Royale Recording (Basically a Modded Balckface Fender type). I found so many different results and had so much fun. There are some old threads here about it. This relates because I have a large selection on hand and understand how the different types shape the eq and sound stage of the amp(s) they were to be tested in.

He is into a lot of clean playing and blues. He has a light touch and doesn't use a lot of drive overall.

Cabinet was an oversized 1x12 with a WGS American Vintage speaker.

The amp had a JJ 12ax7 in the front and a JJ 6v6S as well as a JJ rectifier.

The sound was good. The lows were a bit muddy and the high end could have a hardshness to it. Not a lot of harmonics or anything, definitely needs to run a reverb to fill out the sound. Not super loud but sizeable, it is a 5w amp.

I popped a RCA BlackPlate in the front end and WHOA did the muddiness clean up. WAY bigger sound stage, much more 3-D. There is more 'room' for the effects like Delay to have space. He was astounded. He didn't realize how much better it would sound. Not only was it louder, more 3D and cleaner, but also sweeter with a larger but more controlled low end.


I told him to just wait til i popped in the output tube i had brought for him.....an Old Ken Rad. Black Glass. MINT.


The lows and highs were incredible. Shaking through your legs and enveloping you. It was like swapping on Surround sound! He was just shocked. I was just smiling because I KNEW exactly what that combo would do. He just kept saying how much he couldn't believe it.

We swapped back and forth over and over and there is not even a comparison.

The amp sounds PERFECT. Not even a need for a pedal to fill it out at all. The NOS tubes made it! He told me before he didn't believe me but now he has been texting me all day about how shoocking it is. That amp sounds mASSIVE now Btw.


Anyway,

I gave him the preamp tube and linked him with my tube guy :)

I love spreading the love. Spread the tone all you can!!!
 
Thats what I settled on in my 5F2A build.
Sounds great and what a difference from the new JJ12AX7 I originally installed.

Sorry, actually thought this was the most recent pic.
There’s a RCA in the pre now and also I mounted a Swart Nightlite in the back to attenuate.

This was my first build, wiring is a bit tidier today.
 
I am a huge fan of NOS tubes. (y)
I know that there are only a few companies that are still producing vacuum tubes, but why can't one of those companies get their crap together and make superior tubes again?

And just my honest opinion, but I have yet to find that JJ's sound good in anything.

I have only found ONE amp that I preferred them in against other tubes, including NOS. The Marshall origin. I hate that amp to be honest but the JJs sounded best in there. Surprised me but that amp needs what the JJs round out and kind of muffle. They also have that high mid clack that is normally a no go but is OK in the Origin against other tubes.

What a thing of beauty! He left his as a head for easier combo possibilities but I totally dig this combo you made. Looks sick. Great wiring as well. I find that for my playing, throwing in RCA outputs works better, as the high is a bit softer and mid a bit more prominent. For my blues friend and clean enthusiasts, grab some KenRads for a 3D soundstage you aren't prepared for. The effects and sound overall have so much more space with NOS tubes. The comparison is so obvious in person. Really inspiring. You go from stacking effects to playing hardly anything and just enjoying the rich natural harmonics.its nuts!

I appreciate the kind words, thanks.
Definitely some things I would have done differently now with experience I've gained thru three amps...

Would you mind posting what those things would be? Just curious as I'd eventually like to build one. Or even just the single knob version like what he made for fun.

I appreciate the time and knowledge!

First and foremost, I am no amp pro/guru. I know almost nothing. Handy with a soldering iron. Can read a schematic.

Being I knew absolutely nothing about building an amp, I went with a kit.

The circuit is small and pretty simple. Not really a lot of parts. If I were building today, I’d source all my own parts.

The kit I purchased came with really small gage wire, which I ended up eventually switching out.

Kit also came with those white, Chinese two piece tube sockets. I broke one.
I ended up ordering Beltons and once again tore into the amp.

Caps and resistors I’m not sure what I really got? When I built my second amp, I was able to choose from a couple different ones, name brand.

Board is pretty basic to be polite. No set place to mount it. Ended up mounting it kinda half assed honestly.
I haven’t replaced that yet, but I will.

I had to source my own transformers. Being a Tone Talk listener, went with Heyboer.

For the cab I went with a Weber, tweed, great reputation. It’s “oversized” to fit a 10” speaker.
I decided on a Celestion Alnico Gold. Large bell.
Well the tubes just about want to touch the dust cover. Can’t believe that’s the greatest life expander for tubes?
Honestly though, not sure as I sit here typing how I’d go about the cab again, or head? For me, it was just to learn to build something on and have a small wattage amp to crank.

Creating a shopping list and sourcing my own parts would have saved me time and money. There are many schematics online for this circuit. Probably better kits too if that’s your bag…

My buddy said to source all of the parts etc and to just work off a schematic rather than a kit as well if I go to do it. Good to know all of that stuff. Thanks!
 
Assuming this is a champ type amp I’d also swap the 5Y3 rectifier tube. It can make just as much difference IME

Some of my favorite 6V6’s in my ‘50’s champ have been the 5S2D’s (Italian and Swedish ones), Raytheon, RCA Blackplate and Fivre. I find anything RCA or GE just works well in most vintage American amps

Makes sense! I was also looking at some RCA blackplate rectifiers to test, etc. Give that little amp every bit of magic we can :)
