The Trace Elliot V-type Club!!

View attachment 3202869 In regards,to the amp I have been asking questions on distortion problems. Have come to conclusion to open up the amp,and check to see if tubes may be loose. Don't have another speaker enclosure to see if is the cabinet causing the distortion. Does anyone have any instruction on taking the amp out of the cabinet? I watched a video,and looks like there are 4 screws that have to be removed,and the amp just drops down to be removed? Any comments or help would be appreciated. Thanks!


The all tube versions have four screws in the bottom of the case. Remove the screws and the the chassis slides out the back.

I found this image of a 300H chassis. Although the chassis construction is totally different from the all tube head, I suspect getting the chassis out is about the same.

Unless you have electronic skills, I would not do much beyond blowing out the dust bunnies, reseating connector plugs, and swapping out the two tubes if they are bad.

The amp has potentially lethal voltages, so be careful.

Thank you,very much!! Going to try,using a speakon adapter to for my speaker cable. Other 1/4" plug in on back of my cabinet,seems loose. I can get sound,but distorts. Thinking might get a better connection by going through the speakon cable input. Just trying to see if the cabinet causing the problem. Wishful thinking!

Do you have another amp? Simple test really! I wouldn’t expect distortion from the jack input on the cab being faulty though, more likely to be cutting out.

Forgive if you have stated already but have you tried new preamp valves?

Thanks,but no haven't tried replacing preamp valves. Friend of mine here locally has some we might replace them if needed. I have another amp,but haven't tried it yet,the cab is not here at home,it is at Church,where I attend. Input jack on back of cabinet is counter sunk into the back of cabinet, but you can still plug in but it is not real tight,you would have to see it. I decided to use a speakon adapter to the 1/4" cable,and connect it that way to get a better connection. Still plan on getting the amp serviced,and checked out,to make sure it is okay.

The critical part of your post is a little unclear / confusing to me.

Are you, in essence, saying that the distortion returned, when used with a different instrument?

1. Is the distortion present on the D.I. output?

2. Is the distortion present on the F/X loop?

3. Is the distortion present on both passive, and active input sockets?

4. Have you tried swapping out the pre-amp tube?

5. Have you tried a different speaker cabinet?

6. Have you tried a different speaker cable?

Try a different patch chord always first. Using old tube amps and amps that have been sitting unused get corrosion on the contacts. Turning the chord back and forth in the socket helps. At first there is alot of cracking and popping and cutting in and out but it's just the corrosion.

Thanks,for your comment. I have a picture of the back of the same speaker cabinet I am using. Notice the input jack on this cabinet. My input jack is counter sunk into the back of the cabinet,and the jack is not making a good connection. So I have decided to go with a speakon adapter,and plug into the speakon input,because my old amp does not have a place other than the 1/4" input.

Thanks,Wasnex,I managed to slide the amp out of the cab,and it looks exactly like the one you showed in the image,you showed. I checked the tubes,to see if they were loose,and pressed them to make sure. Both of the tubes light up,and work. Looked it all over carefully,and removed some of the dust bunnies,off the back of the fan. Didn't notice anything loose,and looked at some of the solder joints. I am now going to say,my speaker enclosure is the culprit. Because of the damaged input jack on the back,I got a speakon cable adapter,to get a better connection,or repair the 1/4" jack,so I will have a better speaker cable connection. I have a picture of the back of a cabinet like the one I have. Notice the 1/4" jack input,mine does not have the nut,and the jack showing. Mine has only the plastic part showing to plug in. I can get sound but it starts distorting,after the vibration of the speakers gets loose? Sorry for the lengthy reply. Here is what my cabinet looks like,less the damaged 1/4" input jack. Noticed the build was in 1996,and show 300E?

Try a different cord on the bass and speaker. could be the cord itself. Most likely something in the solid state power amp. Ive never heard any complaints about the v-type pre but a few about those mosfet poweramps. Keep your eye out for a v4 or v6. There's a near mint 66 jazz bass , bound dot neck on Olivia's vintage for 7 grand. A steal.

I'm guessing this was your problem all along and you finally narrowed it down. The amp left me in great shape and had performed excellently during the last rehearsals it was used.
Thanks,cornfarmer,sometimes,you get a lot of comments,and suggestions. Most just trying to help,but don't know the history. I advised different ones,that it had just been serviced,just something might have jarred loose in shipping. I opened it up,everything looked okay. Tubes are still lighting up,and looked okay. I am convinced it is the input on the back of the GK410SBX. Everything is cool.

You can't confirm tubes are good by looking at them.

If the 1/4" input jack is missing the nut, there is a good chance there is a broken solder joint where it connects to the board, which is a likely source of your problem. Replacing the nut and having the solder joint repaired is not a bad idea.

I use a speakON to 1/4" adapter with my V-Type and other tube heads that only have 1/4" outputs. I also use the same adapter with some of my cabinets that only have 1/4" inputs when I am using an amp that only has speakON outputs. The adapter I have looks like this one:

IMHO it's a good idea to get an adapter that uses a genuine Neutrik speakON connector as some of the knockoffs don't work reliably.

Thanks,the speakon adapter don't look exactly like yours,but is a Neutrik brand,from Sweetwater Music,in Ft.Wayne,IN. Should be here in the mail in the morning. I saw the tubes were lit up,when I turned the amp on,and could see them through the fan grill. Hopefully this will take care of the problem.

Just got the speakon adapter,and hooked everything up,and played it for about half an hour,no issues/distortion. Always felt like the 1/4" jack on back of cabinet didn't look right. Now with the speakon cable have a secure connection. Could actually hear the speakon adapter lock in place. Problem solved the amp,is fine,it was the cabinet all along!

Not much going on with Club? Touching back with the issue,of my amp,all along it was the cab input jack,and alleviated that with just going with a speakon adapter,to just plug into the speakon input. Not having any distortion now. Been playing it alot,but have a question about the passive/active inputs on the amp. I have active and passive basses. Never had a tube preamp before. Seems like the volume is higher in the passive input,even if I use active bass. Will I damage the amp,by going into passive input with an active bass?

Feel free to use whichever you please. There should be quite a noticeable volume increase when using an active bass the passive input. The only difference is the input impedance, with the active input designed to the lower the signal strength of active electronics as they have a (generllay) much hotter signal than a passive. Use your ears on this one as you may find the amp clips more easily using active>passive. I often use the active input with my passives to lower the volume when I’m at home.

Using the active input attenuates the signal and slightly changes the sound because the impedance is diffferent. I use an active bass, but on my most of my amps I prefer the sound of the passive input.

If your bass overdrives the passive input, and you find this undesirable, use the active input. Keep in mind that clean boost and tube screamer type pedals can be intentionally used to overdrive the input of a tube amp. In other words, driving the input into distortion is not a problem if you like the way it sounds.
