Question about Peavey Delta Blues 115 30w All Tube Combo Guitar Amplifier

1 Answer

Hi there, and thanks in advance for any help you may give. I find my Peavey Delta Blues either EATS valves or the valves come loose, though I haven't moved it so that doesn't seem likely. I put new valves in a month ago and one of them has just gone on me. Can I use the amp on two valves? If so, I presume it would be either the inner or outer two which I would remove. Do I have to change impedence or anything else if I do this? Any ideas would be a great help. Thanks again.

DO NOT run on less than the full set of valves!!! ALSO when replacing the valves with matched pairs used the matched pairs to replace either the inner two or the outer two. If they come loose, the sockets probably have pins that are loose. Sometimes they can be tightened a little using a sharp scribe to bend them gently inward. I would consider installing tube retainers. They are made as a wire springs. Go to this site:

When playing low notes on my guitar, I'm getting sub harmonics while playing clean on my Delta Blues 210. (sounds like a detuned bass playing along with me.)

That unit has a digital reverb and tremolo that can not be turned OFF with your foot control, meaning this small sound card is always on. Even though that level is on "0", it is still always on. If it has a problem within it, it will put noises into your sound. I would recommend opening the amp, look for the power to the effects card and unplug it to see if it goes away. It should be a small card resembling a sound card from a computer mounted off to the side. It should have a red and a black wire plugged into it. Wiggle it and listen for a change, dirty connections on that plug could do that. Unplug it completely and listen. This would only remove the possible interference of the card, you would still have sound without effects. Regardless of the brand, those cheap effects cards are usually more trouble than they are worth. They only have a few samples of effects, not the actual effect. I hope this helps, I know it is a great sounding amp but, those effects cards are the weakness of amps today.

After playing for a while, approx 15 min, the volume dies away leaving some sound but greatly reduced. It then gradually returns to normal volume after about 3 mins. Otherwise all other functions seem to...

Such a long delay and a slow return to volume is puzzling. If the return came back in say 30 seconds, I would suspect 1/2 of the V1 tube (12AX7) might have a failure of the heater. When it has failed see if this tube has TWO points of light in it. The cooling down and warm up would give a 15 second ramp up or down in volume. This tube has a path around it that would sustain a very low volume. Try swapping one of the other 12AX7's into this spot. If the sound totally goes away replace the one that was in V1 at first place and see if problem goes away.

It rattles....even with the grill off....sounds like tubes rattling but I can't tell

There could be a small tear in the plastic liner over the speaker. If thats the case you can try pressing some cotton on it and then put the grill back in place, or find some fabric glue and glue a thin peice of fabric over the tear.

PV Delta Blues. Resistor R-58. What's the value and wattage?

It appears to be a 430 ohm 5 Watt FLAMEPROOF resistor... The resistance value could also be 470 ohms...

Here is link to a 430 ohm:

Here is link to schematic, however the resistance value is blurred but starts with 4 and is three digits leaving only 430 or 470 as the value:
