Question about Amplifiers & Preamps

1 Answer

Lost power Hello, I have this normally great sounding Deluxe Reverb (1966-ish). It was working perfectly when I last turned it off. I wnt to use it again recently and it has no power. When I turn up the volume it has kind of a compressed sound and no balls. No smoke or symptoms that would indicate a major failure. Could a tube have gone bad? Any thoughts would be helpful. Thanks, Jack RI, USA

    Thanks for your advice. I swapped the tubes with a newer deluxe that I have with no change. Still sounds weak and even cranked up to 8. I think I will have to take it to a local tech to try and find the problem. It worked fine one day, then the next it was weak. I can't explain it. I was hoping a tube was the answer. Many thanks!

Hi jackjohn

It could be a tube, it could be the usual old age catching up with it. I would start with checking the tubes and see that they all light the same way and colour. Also check for white dust in the end of the tube where it is normally silver. Give them all one by one a bit of a wriggle when the unit is going to see that they are all seated properly. It may be a rectifier tube 5R4 gone, replace it out or do some DC voltage checks about the place. remember there are high voltages present!! It A new set of output tubes never go astray in a classic amp like this. Use Electro Harmonix 6V6EH output tubes, gain matched set of course. They work great at higher voltages that these ol girls use. You could of course, just drop it to a Fender repair guy... and he'll be able to sort it out without mucking around. :)

Peavey classic 50 reverb stopped working and now when you turn the reverb knob it makes the tone of the amp brighter and lots of buzz


I do not have one of these but It sounds like an open connection or broken wire. Check the peddle and associated wiring first and be sure it is OK, if possible swap with a known good one to be sure. If it is not the peddle wireing and associated jacks it is probably an open wire on the reverb pot.

How can I fix reverb?


Either the spring driver circuit blew or the SPRING INSIDE BROKE.
You gotta get in there. Take out the spring unit and check if there is a tensed spring in there. If so, check the connectors. Also check the footswitch plug in the back of the amp, plug and unplug a cable several times, sometimes it becomes dirty and does not let signals through. You can check if the reverb has no drive by tapping the spring while the amp is on and the reverb volume is up. If it sounds, your reverb is fine but not receiving input. That would be the driver circuit. Take it to a Tech and explain.... GOOD LUCK !

Line six guitar amplifire...controls


Hi! I have a Spider III 15 watter, but I think the functions are similar. If the "Tap Tempo" light is flashing, you are not in Reverb mode. The light must be lit steady if you are in "Reverb" mode. I notice that you have to rotate the knob that you're working with all the way counterclockwise, and then clockwise to the setting you're trying to get. If you just turn it clockwise from where it is when you power on, it doesn't seem to do much to change the settings. Also, very little movement of the knobs makes a big change. They seem to be very sensitive.
You may want to reset your amp to the factory default settings. This will clear ALL presets that you have saved! To do this, hold down the CLEAN channel button when you power it on. Again, ALL SAVED PRESETS WILL BE CLEARED! Hope this helps.
The Line 6 forums are a great place for info. They will even tell you about "Secret Settings" that are not in the manual. Good luck and rock on!

I have a new '65 Deluxe reverb Reissue Fender Tube Amp and I'm not getting power to the amp after I plug it in and turn it on. Ive checked other things in the outlet and they work, so it is not the outlet....


If you have power and a good connection to the guitar, don't take it apart - take it back. It has a warranty and any reputable dealer will give you another one - just ask for a test before leaving the store/shop.

It might just be the control knob. My fender's reverb went out and it was just the knob.

Guitar amp make large crescendo-like noise, loud pop at end.


Same loudness, no speaker? This sounds (no pun intended) like a filter capacitor shorting out. Open it up and VERY CAUTIOUSLY look for what is making the noise. Filter capacitors can eject hot stuff. Very dangerous.

Further musings on the Fender Amp no reverb problem


Hi, sorry for the delay. Sounds like a faulty cable, or the termination at the jack plug is faulty. These can create the problem you have. What model do you have again, don't remember getting that from you.

Fender deluxe reverb


Hi Hoopnholler

I would start by changing out 12AT7 (V4), is a common buffer stage to the vibrato and reverb audio path. If you have trouble identifying it, you can just swap out with a known good tube and see if it resolves your problem.
If that does not help, then time to go see an amp doctor. If youy are inclined. here is a circuit diagram that you may find useful in faultfinding the problem yourself.

Can't Get solid sound out of Solid State Amp! Tried Everything!


A PROBLEM LIKE THAT SOUNDS MORE TO ME LIKE THE MAIN CULPRIT WOULD BE YOUR POWER SUPPLY WHOSE MAIN FUNCTION IS TO KEEP THE AMPLIFIER FULLY OPERATIONAL. SEEING THAT U SEEM NOT OT BE ANY TECHNICAL GURU, ELECTRONICALLY, I WOULD SUGGEST THAT U REFER THE PROBLEM TO LCAL QUALIFIED AGENTS.
