| Best 6NS7 Preamp for a Pass Labs XA25 amp @skiroe Greetings! I was notified that my name had popped up and wanted to chime in briefly. Yes, I am the same Aric Audio that was selling tube buffers on eBay a little over ten years ago. I was a solid state guy back then and used very low effi... | |
| Pure Class A SS vs Tube Amp Just FYI, all single ended tube amplifiers, large or small, run in pure Class A, and some. When pushed, they will run in Class A2- if the power tube grid becomes positive and draws grid current. Designing a pure Class A tube amplifier is not only ... | |
| Can you tell me why I didn't like the Reference 3a MM's? @jgoldrick Thanks, I'm glad you're enjoying the preamp! I was just looking to help a bit regarding the "high gain" you were experiencing. The 12AX7 has an overall gain factor of 100 and the 5751 is 70, so both of these are considered high-Mu/high ... | |
| Can you tell me why I didn't like the Reference 3a MM's? @jgoldrick the Unlimited can use multiple signal tubes all all different Mu, so having too much gain can easily be remedied. What tubes are you using in the signal slots (ex: 12AU7, 12AT7, 12AY7, 12AT7, 5751, etc.? | |
| Aric Audio Systems Unlimited Preamp @rocray - I definitely second what Kalali posted regarding the equipment on either side of the stream having a large bearing on what tubes may sound best in the Unlimited. I want to also suggest the Gold Lion 12AU7, and 12AX7 (I haven't tried the ... | |
| Aric Audio Systems Unlimited Preamp Hello! I wanted to chime in regarding the remote. I do offer a remote control option on all of my preamp models. It is based on an ALPS blue velvet pot with a motor behind it, controlled by Phillips microprocessor which are mounted on a small PCB.... | |
| Aric Audio Systems Unlimited Preamp Hey guys, It's very cool to hear on the tube tweak upgrade! I will be letting others know about it as another option to tailor the musical presentation towards a slightly less "upfront" character (perhaps to help mellow an overly sibilant or brigh... | |
| Aric Audio Systems Unlimited Preamp @rocray hey, thanks for the follow up post, that's awesome! Offhand, I can understand the soundstage possibly "fleshing out" more using the 5U4GB, for whatever reason it seems to have a more organic presentation than the 5AR4. The gain shouldn't h... | |
| Aric Audio Systems Unlimited Preamp @kalali I would not recommend a pair of OC3s as the regulators as they'll drop too much voltage which will cause the dropper resistor to absorb too much current and run very hot (hotter than it's rated). Using the 5U4GB I would recommend the OC3 a... | |
| Aric Audio Systems Unlimited Preamp Awesome! You're very welcome and please do let us know how it works out! Best regards, Aric | |
| Aric Audio Systems Unlimited Preamp You're very welcome Ray, and much appreciated on the kind words! When switching over to the 5U4GB, the presentation will be slightly more laid back due to the higher internal resistance of the 5U4GB versus the 5AR4, but you may find this is a good... | |
| Aric Audio Systems Unlimited Preamp Hey guys! @rocray , the 5U4GB (not 5U4 or 5U4G) can safely be used in the Unlimited as the first filter cap it requires can be no larger than 40uf, whereas the 5U4 is much lower (the Unlimited uses 33 uf). Using it will lower the B+ voltage just a... | |
| US made, integrated tube preamp able to handle KT150 tubes? Most amplifiers that use the KT150 tube, are also backwards compatible with KT88 and EL34's so there are many tube rolling options available :-) | |
| US made, integrated tube preamp able to handle KT150 tubes? @lancelock - Thank you for the kind words! @jtcf - I don't offer an integrated per se, but all of my amps have enough gain to be used without a preamp and also offer a volume control. Customized units are available as well if more gain, more inpu... | |
