Also, do you have the inbuilt noisegate disengaged?

I did notice that if I plug in the speaker cable to the speaker jack on the back of the amp while the amp is on it makes the same sound for a split second as the jack is touched by the cable.
Umm, I know that certain (if not all) Engl amps have protection for it, but dude running a tube amp without having a load (being plugged into a speaker) risks blowing the output transformer.
You won't hurt the amp by switching ONLY the power on without a load as long as the standby is off. At least I'm am 90% sure of this, so don't take my word for it. I am overly careful, so I'm not powering it on at all without a load...Even with standby off?
Hmm, that is weird, because my tech switched my amp on (only power, not standby) when he swapped the pre-amp tubes. I asked him and he told me it wouldn't hurt it as long as the standby was off.Even with standby on. You should NEVER run an amp without a load. Quickest way to fry your transformers.
Some amps have protection, but that doesn't mean it's a good idea to do it.
I'm 99% sure you've got a microphonic preamp tube.
So I can replace it with any tube that has the same rating? How do I find the bad tube? If thats what it is.
Thanks for clearing that up, repped!I'm 99% sure you've got a microphonic preamp tube.
About the age old standby thing. It IS 100% safe to power on an amp in standby, not connected to a load. People do it all the time and run their effects send to a recorder with cab modeling. A comparison, people run stereo power amps, my self included, with one side of the amp in standby (connected to nothing) as a common practice. Doesn't hurt a thing. ONLY the heater circuit is active when standby is on. The power transformer is not active at all.
I was kinda thinking that. In the box from ENGL came two extra ENGL ECC83 preamp tubes. Do most amp companies ship out a few extra tubes with an amp just in case? Now how do I find the one that needs replacing again?
Thanks for all the responses in the last couple days, I've been super busy and didn't see Leo's question. I agree its most likely a pre-amp tube issue![]()
Basically It turns out the V5 input stage preamp tube was microphonic so I switched it out with the tube that came with the amp labeled "use as input tube only" whereas the other spare tube that came with the amp says "for use at any position". Long story short and after a quick 5 minute changeout and my first time changing a tube, I can say that my amp is running great and sounds brutal. Im glad I asked in this thread. I didnt want to start a new one. Thanks guys! And as far as the thread, I cant blame you Zimbloth for making the switch. ENGL rules!![]()
