Yes, they are matched Electro-Harmonix EL84's.

So I got a new set of MATCHED EL84's from Tubedepot.com (I highly recommend them) They are cheap and reasonable!! Nonetheless, I put them in and they each biased to 25 mV +/- 0.5 mV.

I just looked at my receipt and thought that I had purchased a matched set. Turns out they weren't a matched set.

Yes Electro Harmonix brand

Hey everyone, This is my first time swapping out tubes. I ordered a matched set of EL34's with 24-hour burn in. I put the new tubes in, let it sit in standby for a few minutes, took it off of standby. I measured the bias on V2 and adjusted to 25 mV, I then measured V3 and was reading 35mV. I adjusted it to 25mV and then measured V2 again and it was 15mV. So basically I have a 10mV difference between the 2. I assume this is not normal. Any way to adjust them independently?

Anyone else had an issue where 1 of their strings is constantly out of tune?? I've basically had this issue since day one. Initially I just thought it was because the strings were new, but over time I've just been dealing with it. Now it's to the point that I'm wondering if something is wrong with the guitar. The guitar is about 10 months old and still have the original strings. I keep my guitar in the gig bag (which I hate), when I'm not playing it. I only get it out during rehearsals and performance and the first thing I do is check my tuning. Most of the strings are out by a couple of cents or so, but the G-string is ALWAYS down to at least a Gb?!? Before I go and completely blame the guitar itself, do you think it could be a result of the gig bag being laid on its side during transportation? The G-string tuning peg is the top right tuning peg when facing the guitar. I've heard of B strings not staying tuned, but the G string kinda leaves me baffled.

Also on your FX Loop settings, make sure that your values are setting accordingly: SEND: 100% RETURN: 0% MIX: 100% This ensures 100% of your signal is sent via the FX Loop Send and NONE of it gets passed to the DT amp.

At the bottom of page 2-7 of the POD HD500X Advanced Users Guide there is a Note regarding Output Options that says: "this mode setting affects the signal fed to several POD HD500X outputs: Balanced, Unbalanced & Phones outputs as well as USB Record Send & L6 LINK audio outputs" Which to me reads that the FX Loop Send/Return is NOT affected by the Output Options setting. Therefore I'd leave the Output set to Combo or Stack Power. Once the signal leaves the FX Loop Send the POD is done and provides NO other output (L6, Balanced, etc.). The only way it could is if you were to hook up to the FX Loop Return, then the signal would be sent to the normal outputs (L6, Un/Balanced, etc.) Hope this helps!!

If you're going the direct out route from the HD500X, then I'd be using either the 1/4" outs or the XLR outs. Also double check that the Output (Hold View-->Page 4 (Outputs)) and make sure that Studio/Direct is selected. Personally, the following is KEY to getting good tone out of both the POD and the DT: If you're going to use the POD and the DT together via L6 Link, you need to make sure that your "amp" selections on your POD are the PRE-amp versions and not the full amp versions. In this case make sure that the Output (View--> Page 4 (Outputs)) has either Combo Power (DT25 Combo) or Stack Power (DT25 Head). I love the tone of my DT25 head cranked, but I use the Direct Out from the head into my recording interface on the computer. I also have a dummy load box connected to the amp, so the amp thinks there's a speaker cabinet connected, which allows me to harness the Power Tubes.

I agree that taking the amp out of the equation takes all the fun out of playing. Once I got it dialed in with the POD and the DT talking to each other the way they should it sounds awesome! The whole reason for taking the speakers off of the stage is so FOH can have more control. As I originally said we are going to an In Ear Monitoring system, so what I hear in my ear is coming from the mixer and not the stage. So, on stage speakers wouldn't really do me any good.

I built a selectable load simulator (4-Ohm, 8-Ohm and 16-Ohm) that fools the amp into thinking there is a speaker cabinet attached, then take the Direct Out, and it sounds fantastic!!! I'm super excited and can't wait to try it out at the next rehearsal. It has that tube warmth and fullness that I just wasn't getting from the POD alone.

OK, I was messing around with it some more and realized that: A: Direct Out will ONLY work in "Full Volume Mode" if Standby is OFF and a speaker cabinet load is connected. Last night when I was messing with it I did NOT have any speakers connected and could only get a signal in Low Volume Mode, not in Full Volume Mode. B: The DT25 sounds damn good when cranked in Full Volume Mode. I recorded a few samples from the Direct Out in the various output modes to compare. The first was in Full Volume Mode, then Low Volume Mode, and lastly removed the DT25 altogether and recorded straight from the HD500X. The average person probably wouldn't be able to tell that much of a difference, especially in a "band" setting, but I'd rank them in that order too. The best was Full Volume Mode, then Low Volume Mode, and the HD500X sounded a little flat and didn't have that "warmth" All that being said and given my situation is there any reason I couldn't hook up an external speaker simulator that emulates a cabinet load and then use the direct out?

I bought the DT25 head a few days ago, for the sole purpose of playing in church where I intended to use the Cabinet Simulated Output (Direct Out) straight to the PA. We're going to an In-Ear Monitor system and want to eliminate all speaker amps from the stage. I thought the DT25 would be perfect since it's still a FULL TUBE amp with no speakers that I can control from my POD HD500X. However after connecting via the POD via the L6 link and then the Direct Out to a recording audio interface (Presonus Firepod), I realized the Direct Out is only usable in "Low Volume Mode." Come to find out when using this configuration I'm only using the amp Pre-Amp section and not the power section of the amp. So my question is am I really gaining anything by using the DT25? I was just plugging my POD HD 500X straight into the PA and getting decent sounds. I thought getting the DT25 would step it up a notch, but if I'm not using the Power Section of the amp I don't know if I'm really gaining anything. Anyone that can chime in would be helpful!! Thanks
