A place for tone seekers to discuss tube amps and analog goodies. Vintage or new, boutique or not, let's talk about the sweet tone makers.

Welcome to r/ToobAmps - A place to discuss that sweet tube tone. Whether you're a toob noob or Leo Fender reincarnated, you're welcome here.


SAFETY FIRST!

Tubes amps make use of very high voltages! These voltages can kill you dead. If you decide, whether suggested to you here or not, to open your amp and tinker with it, PLEASE BE CAREFUL, and learn how to do so safely. Even an unplugged tube amp can retain enough juice in the capacitors to give you a very, very bad day.

Please read the Tube Amp Safety documentation.

HELP ME!! Someone explain what kind of attenuator i should be looking for?

I have a 67 bassman that is so freaking loud, but I love it so I'm thinking about getting my first attenuator. I know absolutely nothing about these things and there seems to be a crap ton of options out there. I don't wanna spend a 500 bux but i also don't wanna a piece of crap. Just looking for some guidance here. Also, if it matters, 67 fender bassman 50 watt 4ohm. Thanks peeps

Inconsistent volume Fender Hot Rod Deville (2x12) issue

Hello all, a few months ago I got myself my first tube amp; a used fender hot rod deville. And recently I’m starting to notice that sometimes the volume goes down randomly. Sometimes the volume goes down a bit and other times it produces practically no sound. It kinda sounds like it isn’t getting enough power or something. What should I do/check? I really hope this issue doesn’t happen during a gig, and then having to wait 5 minutes or longer until my amp decides to play normally again. Is it possible I have to change my tubes? If so how do I decide which ones to buy? Does every tube amp fit different tubes? (I’m a toob noob)

Does anybody have some advice for me?

Silvertone 1484 Tubes

K just acquired a silvertone 1484, please help me figure out tubes! It is missing its tubes, I need (2) 6L6GC, (2) 6CG7, and (3) 12AX7 (it has 1 of the 4 silvertone 12ax7s. I'm trying to get as close to original as possible (without breaking the bank ideally). Does anyone have any recommendations for what to use or use in place of the stock tubes, which I believe are RCA. I've read about Tung-Sol and other brands, so let me know if you have any experience thanks!

Why is the Marshall Origin 20 cheaper?

Most 20W tube amps are going to run close to $1000. What gives? There has to be a catch.

Is there a way to use the attenuator in the tone king imperial on another amp ?

I love my tone king imperial. I think the attenuator is great. I would like to use that attenuator on another amp. Is this possible?

Bugera V5 Infinium - Tube Life Monitoring LED

I've had this Bugera V5 amp for a few years now. Recently, when I turn on the amp, the front LED starts blinking, and the back "Tube Life Monitoring" LED remains lit.

Usually this means it's time to change the power amp tube. I tried replacing that and the preamp tube and the problem remains.

So, I think there's another problem happening. I don't know enough about what to try or test next. Any advice?

Traded a Blues Jr III for this behemoth, Traynor YCS100H2. It is massive. I still can't believe what a deal these heads are. Three full independent channels with separate EQs and loop level controls. The most versatile head I have owned since the Mark I of this amp. And POWER!!!!

(HELP) bedroom player buying toob amp

Currently playing a THR10, but id like a real amp now. I live in an apartment, i play mostly clean or edge of breakup blues, and some jazz. I have a multiFx for effects. 700€max

BJr tweed 420

supro royale 1933r 2x12 680

blues deluxe (edited from deluxe reverb) 600

delta king 12 500

my main idea was getting the BJr (sounds dumb to say but its in part because of the looks, and because i can resell it easily and not lose money) , but the royale reverb for that price seems insane.

other ideas are apreciated of course

[Help] New Tube Owner, High-pitched Noise From Back of Amp?

Hey Everyone,

Sorry for the annoying post but I just had a new Harmony H620 delivered to me today and discovered a low-volume, high-pitch whining noise coming from the back of it where all the tubes are. It does not come through the speaker, is persistent whether something is plugged in or not, and is the same volume no matter what I have the master volume set at. Here's a recording of it: https://drive.google.com/file/d/1WZVtlZDB3ZozPSk0ZOxN-NSMY-0DIEnC/view?usp=sharing

This is my first tube amp so I would appreciate some insight from you all. Thank you!

UPDATE: This sound is produced by a bad power tube according to one of the employees at the store I got it from. Exchanged it for another one and no noise. It might have been damaged in transit, who knows. If your amp is making a noise like the one I encountered, get it checked out or return it if it's new.

I know this is going to put me in circlejerk 😅

So I have had a few amps as an amateur permanent beginner. Most have the controls on the top which I found not very easy to access if you want the amp at ear level. Then some have controls in the front which is far better i think. Less durt to get into the jack socket/electronic behind and on the knobs. And one can put things on the top or stack easier. So why are they still doing those top controls setup? Tradition ? Do you have preferences?

Did I just ruin my Deluxe Reverb?

Hey guys :)

I’m a total rookie with amps / electronics. I just purchased a used 2004 deluxe reverb reissue. I pulled it apart and saw the filter caps were in rough shape.

I’ve upgraded to F&T caps by myself, following along one main YT video, plus many other videos to ensure I was working safely.

The solder joints look decent. Polarity all faces the correct way. I left off the cap at C31, as per Psionic Audios video: https://www.youtube.com/watch?v=pkIEfH0ZC7w

I also unsoldered the bright cap at c10, leaving one leg in tact.

Now when I turn the amp from standby to on, it makes a loud hum that seems to want to grow - I shut off the amp right away.

The power tubes are starting to glow red at this point.

I don’t see any bad soldering work or bridges.

Not sure if I knocked something out of place and did t catch it. Could this be a loose tube? Issue with the speaker load? Maybe I squished the cable or something?

I'm not sure where to look. Any ideas?

Thanks very much!

Valuable Vacuum Tube Brands

What brands of Vacuum Tubes are worth money like if I find a collection someone is selling for cheap? Probably "Western Electric" would be one Brand and maybe Gold Lion?

Captor X Ohms - confused

Hi all - I’ve got a Vox AC15 (whichever is the cheap one) and a Marshall Origin 20c. I also have a very stroppy neighbour.

I’m looking at getting a Captor X to use as an attenuator, but also for the IRs so I can play silent (the neighbour is very stroppy). What I’ve seen elsewhere tells me that the 8ohm version is fine for the attenuator so long as I “don’t play at very high volumes”, but I’m unclear on what this means exactly - does that mean so long as I don’t crank the amp (which is kind of the point) or so long as I don’t send too much signal to the speaker?

Somewhere in the future I’ll upgrade the Original to a JTM Studio or Bluesbreaker.

If anyone has any advice here it would be greatly appreciated - will the 8ohm work for attenuation or do I need the 16ohm? How compatible will each be for future purchases? A little change in tone won’t bother me, but I don’t want to blow anything up. I am 99% playing at home, not live.
