| Inherent Difference - 12AU7 and a 12AT7 Stickman as I mentioned they should work without issue but if you go to the web and look at the tube data you will notice significant differences in the voltage and current characteristics of these two tubes. Kind of like driving a Porsche with a ... | |
| Inherent Difference - 12AU7 and a 12AT7 Because these are different tubes and not really interchangeable it's hard to give you an answer. The 12au7 has a gain of about 19 and the 12at7 is 70 I believe. You would need to change the biasing of the tube to get it to perform to it's best. Y... | |
| Can anyone tell me how my amp compares? The 302b and the 502 Jolida are the same amps. The circuit and transformers are the same. It can be changed to use KT-88's or EL-34's by changing four resistors in the bias network. My 502 run's both KT-88's and EL-34's. You may or may not like th... | |
| Sufjan Stevens - All Delighted People EP It's good. I haven't been able to get into it like some of the other stuff he's done but I've only listen to it a few times. You may also like "One Eskimo". | |
| I need a lower gain 12au7 for Mastersound The 5751 has a gain of 70 compared to the 12au7 gain of 19. I've never heard of using that in place of a 12au7. I do replace 12ax7's with them and like them. As far as low gain 12au7's I don't know of one. Someone may give recommendations for a t... | |

| New To Tubes Advice Needed Hi Rossq, I would first give the unit some time to break-in and for you to become familiar with it's sound. Then you may want to try they 12ax7 and the 6sn7's first. You only need one 12ax7 so you could do that one first. What kind of sound do you... | |
| Speaker input question for Jolida 102B Your hookup is fine. The black one in the middle with 0 is ground. It takes some time for the unit to burn in. Let music play on it as much as possible for about 100hrs or so and then take another listen. You can then try the 4 ohm connection and ... | |
| use headphone amp as pre amp? I'm sorry I should have been more clear when I said try it. You will need to plug this into a device which does have a volume control like a preamp or receiver. DON'T go from your CD player into OBH-11se directly into the amp unless your CD has a ... | |
| use headphone amp as pre amp? I have one of these in a drawer somewhere so my comment is only from memory. I believe the output is fixed and will not adjust using the volume control. If my memory is right the answer would be no. Hook it up and try it to be sure. | |

| Best caps for updating my VTL 225 mono's ? 16 caps would be really expensive to do with V/caps. I'm sure it would sound great but! There are several capacitor write-ups you could look at. Jon L. Enjoy the music and http://www.humblehomemadehifi.com/Cap.html is another good one. For cost an... | |
| Can I use 6x4 instead of chinese 6z4 for rectifier They are both tube full wave rectifiers but they are not wired the same. You need to change a couple of wires. I was looking at a supply this past weekend that used the 6z4 and the 12at7, 12B4A. I asked if it could be switched to the 6x4 and the s... | |
| Shipping Speakers to China - Which Shipper? I'm sure there are many options as far as shipping companies. Don't rule out Hong Kong based companies as they speak English and can help with the customs issues. Beware of sending them direct via the manufacturer. I bought a pair of Vandersteen's... | |
| have i diagnosed my hum? Soundgam,How old is your amp and approximately how many hours on the tubes? Also did you try to bias the tubes after you put them in? You can also try to change out the 12ax7 and 12at7's if you have an extra set or at least pull them out and clean... |
