Question:	whats the difference between 12au7 & 12ax7 tube for conrad johnson pv10bl pre amp
Answer:	I don't personally own that guitar, but I looked up the dimensions, and it says it is 48" long. The bag is only 41" long so my guess is probably not. I would make sure you know how long the guitar is before you buy the bag.

12AU7 / ECC82 Preamp Vacuum Tube

• 12AU7 / ECC82 Preamp Vacuum Tube

User questions & answers

Question:	I assume 12 AU 7 is two tubes in one obviously maintains stereo sepeartion Common cathode which is grounded normally anyway
Answer:	To be precise, the 12AU7 is two independent triodes in a single tube. Like any other electronic component, these can be used in all sorts of applications, limited only by the circuit designers imagination and ingenuity. They can by used in audio and RF circuits... These could be used in a stereo design, but they are not limited to that application. The cathodes are not common between each section, and depending on the circuit design may operate at some potential other than ground.
Question:	Can these tubes be used in a vintage Vibro Champ
Answer:	Read through a few articles about your vintage Vibro Champ, and it looks like the consensus is that this tube would work better for the V1 position. V2 would be a 12AX7, V3 6V6, and V4 5Y3GT. It is my understanding the 12AU7 has less gain. You could try a few different tubes in the pre gain to see what you think.
Question:	pin
Answer:	Yes, this tube has 9 pins.

User questions & answers

Question:	Would the Gold Lion 12au7 be a better choice over the Psvane version of the 12au7 tube
Answer:	Hi - In looking at your dimensions, your pedaltrain will not fit in this case. The length of the case, as you see is 4" longer. The biggest issue would be the depth. If your depth is 14" and the case depth is 14", you will have no clearance to remove the pedaltrain in and out of the case. Typically, the board will sit on top of the tray. Christine
Question:	If purchasing two, will they be a matched pair
Answer:	I used brackets and screws to mount a FX8 to the bottom. There is a layer of foam with a carpet top, so it threw me off on the depth and the screw tips poked out the other side :( so be careful. That only happened on the screws I was pushing hard on, if you use normal pressure and screws that aren’t longer than 3/8 inch.
Question:	Which one would be better for vocals and mid range the gold lion tube or electro-harmonix 12au7 eh vacuum tube
Answer:	Hi - This case does not come with dolly wheels or rubber feet. With that said, we certainly can add these upgrades to this case and would need to be ordered directly with our sales team. They can be reached at 631-557-0000. They will be more than happy to assist you any way they can. Christine
Question:	Is this item single or pair
Answer:	The neck width is 6.5 inches. The neck circumference is 18 inches. The "neck only" height is about 20 inches (and the length of the entire case is 43.5 inches)

User questions & answers

Question:	Does this boost sound enough to use as the only amp to listen to records with headphones
Answer:	Short answer: no. Long answer: this amplifier expects about 1 Volt input for a full power output. A phonograph player only generates output in the .005 Volt sort of range. Also, the signal from a phonograph has to go through an RIAA filter to recover the low-frequency information. A record would not be able to wiggle a needle correctly to generate bass, and so RIAA equalization is applied during record pressing.
Question:	I mostly listen to music in digital format (MP3) and trying to decide between this amp and a USB headphone DAC...thoughts
Answer:	You're comparing Apples and Oranges. The Bravo is strictly a headphone amp. I use my Bravo with a Behringer UCA222. I chose the Behringer because it's a DAC (digital to analog converter) and an ADC (analog to digital converter). I use the Behringer to "rip" vinyl to FLAC files. Why bother with sonically compromised MP3 files when storage space is so cheap?
Question:	I don't know much about tube circuits. Do both headphone channels go through the tube at once and remain seperate channels? Or are they combined
Answer:	The answers about being two separate channels in the tube are correct. But there is an issue in the amp that needs a simple modification. Because of the way it was designed, there is an issue with balance and separation of channels. If you balance to one side or the other, there is still sound out of both left and right speakers or headphones. See the first post on this forum, just scroll down to the picture entitled 'Crosstalk improvement', which is the 6th picture, for details: http://rockgrotto.proboards.com/thread/5297/bravo-12au7-mods-appreciation-thread And be sure to get some different old stock tubes on "The Bay" from the 50's and or 60's. The RCA Clear Top is my favorite so far.
Question:	Stupid questiion of the year. How do you use this and what do you use it for
Answer:	Another more pedestrian use is if you have high quality, high impedance headphones and want to listen to a consumer-grade device (e.g. iPod). Standard headphones are around 32Ω impedance, while higher-end ones can be anywhere from 80Ω to north of 600Ω. The device will still drive the headphones, but the sound may be quiet or sound muffled. A headphone amp does what it says on the box, and amplifies the output -- which results in louder and clearer sound on high-impedance headphones.
