"2nd verse, same as the first"

Please pardon me, I am a bit perturbed at the moment.

So, I replace my stock Egnater preamp tubes with some I bought from Doug's Tubes AGAIN, and AGAIN, the amp has little to no output! I replaced the stock tubes and still little to no output. Are the preamp tubes Doug sent me bad? Any other experiences with changing tubes?

This happened in November exactly the same way. I took to a local shop here in Phoenix (Field Services) and they told me "2 weeks", but took a motherfuckin' month to "clean the impedance switch" and "replace the mains fuse". When I'd call, they acted like I was interrupting their fuckin' coffee break!

Bruce - get hooked up with a better shop here in Phoenix (like Mtroniks)!!!

So I looked at the fast blo fuse, and it looks just fine. I'm not sure where the hell the "mains fuse" is at or if the fast blo fuse is it???

I plan to call Egnater tomorrow, but I really want my amp NOW. This amp has extinguished my GAS for other amps, but if I've gotta be a month without it again, I may just have to settle for less and hang my Egnater hat up for good. :no:
 
I'm not sure I get what's going on here at all. You put new preamp tubes in and they did not work so now the amp is in the shop getting what done to it? Clean a switch and replace a fuse. How are preamp tubes blowing fuses? :confused:
 
you replaced the preamp tubes, but did you try the power amp tubes?

The first time I took it to the shop in November this was all they did. And at this point, the shop told me that ALL of the tubes were fine, power tubes included. I've had the amp back from the shop since the beginning of December, and it's worked fine since, up until the point I tried to put new preamp tubes in tonight.

The amp has had the original power tubes in since I got it, and have been working fine, even since I got it back from the shop. Looking at the power tubes, they look okay, no red plating or blue sparkage, although, this is only LOOKING at the power tubes.

I, too, wonder how in the hell a preamp tube can blow a friggin fuse??? That baffles the hell outta me! It's gotta be something more than just that, and I would have figured that the shop would have taken care of that problem the first time.

Thanks for your replies!!!
 
Bonedish, that really sucks man. I feel bad that you've been going thru so much trouble with your amp.

That being said... and I know this isn't what you probably want to hear, but you should have at least *tried* replacing the power tubes before bringing it into the shop again. Could have saved you some cash.

Power tubes can look fine, and still be bad. Or at least bad enough to blow a fuse.

Just my opinion.
 
Which preamp tubes did you put in? I remember when I had my modular rig that Tung Sol 12AX7s would cut the output of certain modules. I don't know if the same thing can happen with the Rebel, though.
 
RockStarNick - thanks for your reply. I'm sorry if my previous posts were written weird, but the amp is NOT currently at the shop, but I am dreading taking it back, especially if they tell me 2 weeks & keep it a month without calling to notify me! Thanks to your post, though, I am going to try the steps in the manual to see if it is indeed a power tube. I'll let you know the outcome either way. Thanks again for pointing me in this direction!

Resonant Alien - funny enough, a Tung-Sol is what I put in V1!! I did take it back out and replaced it with the original Sovtek, but still no output. What did you have to do in order to remedy this? Thanks again for your post!

Egnater - I am curious as to why, if indeed it is the Tung-Sol preamp tube, this would occur?

Again, I'll ley you all know how it goes, but for now I am off to the Radio Shack for some fuses!
:rock:
 
Blown fuses are normally from bad power tubes.

You should also contact Nate or John at egnateramps.com and they can help you diagnose the problem.
 
Well crap! I just got back from Radio Shack and they do NOT have the types of fuses I need. To be fair, though, the fuse does not appear to be blown. The metal wire is still intact, so my guess is that it's not a power tube?

Any other suggestions?

Any suggestions as to where I might get the correct fuses? Any Arizonans know of any places?
 
Thanks!

Well, I tested the 3 fuses and they came up reading 0.6, 0.9, and the 3rd was all over the place!

With the 0.6 and 0.9, would these be considered blown, or okay?
 
My heart bleeds for you bro!!!! :cry:
That is a great amp..

Do you have a continuity setting on your meter? That's the best way to test fuses IME - if it beeps, then there is a connection from one end of the fuse to the other, so it is fine. If it doesn't beep, the connection is broken.

As for the TS 12AX7s in my modular rig - I just took them out and put JJs or the Sovs back in, and it was fine again. Whenever I put the TS back in, it cut the volume.

To be fair, there were other folks using the TS 12AX7s in their modules without problems, but it was definitely reaking havoc with mine :confused:
 
Just got my R30 back and it turns out it was just the phase inverter tube. :doh:

Apparently, both the Egnater Sovtek and my new Penta Lab were going bad on me! I put the new Penta in there thinking I shouldn't have a problem (being a new 12AX7 and all), but alas, I will have to contact Doug at Doug's tubes to replace this tube.

Now, if I had just taken the time to try swapping out the other good tubes I have handy! Damn, I feel stupid. :doh:

But now I have MY amp back!!! I am so friggin' stoked!!! :rock:
 
What, you don't have a dozen extra power and pre-amp tubes laying around from previous learning experiences in the tube world? I have a great collection. mmmmmmm, love those pre-amp tubes with a nice cheese fondue. Eat them straight from the amp while they're warm.

I had a TS 12AX7 die on me after 2 hours. I really liked the tone I was getting with it in my Brahma too. It went from sweet to crackling and then to nothing.

Exactly hippdog, this what gets me about the original posts. Negative statements like these on very public forums are really self serving. He also took the same song and dance over to the Gear Page and ragged on Egnater over there too. 3 minutes of trying different tubes instead frustration and aggravation aimed in the wrong direction serve no purpose but to damage a brands reputation. :no: I think it is irresponsible to do this.

Dude ... it's a tube amp, have spares, learn about the amp, know what you are doing FCS!!!

I'm thinking you need to reread my post. Reread and understand it.

Yes, I was frustrated, but my honest aim was to get answers (look for the question marks in the OP - that means I don't know everything about tube amps & I was looking for some help). At the same time, I was also venting my frustration, which, I admit, could have been worded more nicely.

You must have come out from the womb being an expert on tube amps. So much of an expert that you really didn't even leave a noob like myself some helpful advice.

Please try and remember that sometimes others are still new around here and post here because they need help.

Again, I am still learning about tubes and tube amps.

That all said, I want to thank Nate at Egnater for his flawless customer service and bearing through all of my questions and concerns via email.

Also, my experience with Field Services was a complete 180 this time, as the tech I was dealing with before was not very good at customer service. This time around, another tech took care of me and was very appropriate.

Thanks to everyone here who took the time to help me out on this thread.

I deeply apologize if I came off as an Egnater basher, that was never my intent.

Geez, I feel like I gave a friggin' acceeptance speech!!! :no:
