Hi ohmytom

Yes, they could be causing the problem.The filaments are a little hard to see sometimes, you will always get a little microphonic activity about preamp tubes. It may also have failing capacitors depending on how old it is. Is it a "Twin Reverb". Let me know the exact model and we can be a little more specific of the problem and solution. Cheers

I have a '93 Fender Blues deluxe tweed and don't seem to have any reverb, am I missing something?


Check the connection to the reverb tank (rectangular box usually sitting on the bottom of the amp). There are a pair wires that connect it to the amp. If wires are connected, and the reverb is not working, you may need to replace the reverb tank.

The reverb channel on my fender twin feeds back


Not sure of how it is feeding back. Two possibilities... the reverb tank in the cabinet is no longer shock mounted. The other is your guitar can "hear" the speaker... make sure you are away from the amp. With the reverb on, the feedback stability is less than with it off so make sure your guitar is away from the amp. Acoustic guitars are more sensitive to this than solid body ones.

How do i connect the boss gt 10 to a fender blues deluxe amp and bypass the amps preamp


You can plug the output of the gt10 into the "power amp in" jack of the Fender. This bypasses the preamps in the Fender but uses a buffer amps in the Fender to drive the power amp. Please note that the reverb is STILL in the circuit when you do this. You can turn the reverb to zero if you wish to disable it.

Fix Reverb unit on Fender Hot-Rod Deluxe Amp


Could have broken a spring in the reverb tank, or a wire connecting it to the amp, or the reverb driver tube, or a few other things, but those are the most likely in this situation. Thats what I'd check first. Give it a little slap and if it vibrates like normal, your spring is probably ok, you can still open it up and double check though. Check your wires. Then pull your reverb driver tube and replace it. If that doesn't work, it is probably in the circuit somewhere, and you should not work on your amp unless you know what you are doing. They store large amounts of electicity in the caps and they can kill you.

Hi, I've owned a Fender Hot Rod Deluxe since '01. Around '06 I started having problems like crackling sounds when on but guitars volume was all the way down. Loss of volume here and there. While amp was on...


In YOUR amp, take a pencil and tap teh sides of the tubes GENTLY, listening for any crackling... note SOME microphonics is normal in the preamp stages.

Since retubing it fixed it once, it is likely either a tube was bad OR a pin of a tube wasn't quite making so replacing the tubes cleaned it and made it work. Tubes DO go bad, especially when they are vibrated like in these amps... BUT don't just replace the lot, try to find which is at fault..

On your friends unit, LIKELY an electrolytic bypass capacitor for one of the reverb preamp stages has dried out and needs replacing.

Fender deluxe reverb amp keeps blowing tubes


If it's blowing fuses. It probably has a bad output tube.
If it's blowing tubes. It may have a cracked tube socket.  Also may need to be biased by a tech.

1974 FENDER TWIN REVERB HAS NRE TUBES NEW FILTER CAPS AND WAS REPAIRED BY RETIRED AUTHORIZED FENDER TECH. PROBLEM AMP HAS VETY LOW OUTPUT UNTIL YOU CRANK IT TO 8-10 THEN IT SOUNDS HORRIBLE DISTORTED AND...


This sounds like a power supply problem. The high voltage for the tubes is not right. Either you are missing an amplification stage because this or one of the coupling caps is faulty. I'd have to see the unit itself to give you any more details.
