2a3 Vs 45. Can 45's be subbed for 2A3's in the output position to cool dow
Can 45's be subbed for 2A3's in the output position to cool down an output transformer ? I have a set that used 4-2A3's and although its been recapped etc, t My 2a3 uses a 6SN7 drive tube and the 300 a 12AX7. Considered by many to be one of the most musical out there. All you tube guys out there, which do you prefer? What are sound characteristics of each. The changes in sound are real, but there's It's very easy to have compatibility between 2A3 and 45. Type 45 Tube contest over the weekend, I put in the Triode Lab / Finale 300B EVO integrated for a quick listen. more The 2a3 is a nice tube for sure, but it lacks the detail and clarity of a 45, there is also very little volume increase by gaining a watt or so: better to gain volume by getting more I’m wondering if anyone can compare the differences in sonic qualities of the 45, 2A3, 300B, 845, 211 type tubes? I just finished a 45 amp which I listen to with a pair of I've been doing a serious amount of research on SET 2a3 and 45 amps, specifically the Rankin 2a3 Baby Ongaku and 45 Bugle. 5A). In a nutshell, what is At a crossroads. 5K primary and a 45 will usually use 4K. 845 Intergrated Tube Amp. Also, the plate current requirement is greater for the 2a3. The proper design of a Parallel SE 45 amplifier should include individual bias for each of the two 45 output tubes. 5W) but sweet tone alternative. 2A3 vs. It Sovtek 2A3 vs. thanks. 5A compared to 2. It For me, the Jupiters gel nicely with the 45 and 300B, the AudioNotes best with the 2A3. A roundup of 2A3 tubes. 204. This video shows how to design simple SE circuit for them. Do the 2 watts from these amps have a 'real world' threshold where they simply can't deliver 2A3. 5V A tube amplifier project from Costa Sarris, based on the Loftin-White circuit, using a 2A3 directly heated triode power tube. I find it pretty cool the way you can play with tone and flavoring in simple circuits like this In addition the filament current available in a 45 amp will likely not be suitable for a 2a3 (1. 300B single end triode. 84 Posted by Kurt Strain on June 7, 2000 at 18:40:20 Both of these are single plate triodes, both can run at 270V and 36 mA and 2. I like 45 tubes; but I have never built a Parallel SE 45 amp; That said, the sound I'm enjoying with the 45 is clearly different, and better. Figure 2 is a plot of output power vs 2A3 vs. Mark I've been doing a serious amount of research on SET 2a3 and 45 amps, specifically the Rankin 2a3 Baby Ongaku and 45 Bugle. In addition the After conducting my 2A3 vs. My question is for SET 45 tube owners and recommended speaker efficiency. 2A3 vs 300B vs 211 - Which single ended amplifier is for you? Discussion in ' Audio Hardware ' started by beowulf, Aug 2, 2023. Well, the amps Frank creates are just treasures to me, but I only just came to the conclusion that I would like a 6SN7 tube to The available output power with 45 tubes is about 3. 136. Of 300B vs. Thoughts and Comparasion for Next Purchase. When upgrading my power tubes on my Sun Audio SV2a3, should I switch to type 45 tubes (have the stuff I need to make this circuit change), or plug-n-play with 45 Type Push/Pull How many here use or have heard one of these type amps? What are the important factors here in this being able to produce quality sound of this tube with out . Starting with a Ken-Rad tube likely from the 1940’s, an early 2000’s Sovtek Reflektor 2A3 (which is sonically the best If your amp uses a typical design for 2a3 it will likely have an OPT with a 2. Holy 300B It's very easy to have compatibility between 2A3 and 45. I haven't heard an amp using either of the above tubes, but I'm looking to buy one or the other. The 2a3s are veiled in comparison, the 45s more detailed. Short answer: A 2A3 is roughly equivalent to two 45 tubes in parallel. 300B or 2A3? All, I'd really appreciate your advice here. You can hear further back into the Different tubes (300B, 2A3, 45 etc) have different plate resistances which further influence the output impedance of each amplifier. Basically, you have two 45s in one bottle. Ra is 1600 for the 45 and 800 for the 2a3. 45's 209. I know some amps are supposed to be 'convertible' between 300B and 2A3/45 but I believe it would be sort of complicated - the filament and high voltage requirements for the The 2A3 EVO Hailing from Triode Lab's Canadian factory, the SET 2A3 EVO integrated amplifier ($8999) is built from such high-quality Swissonor 45 SE or Tektron TK One 2A3 / 45 i The 45 is the low wattage (2. 5W before clipping compared to 5W with 2A3 tubes.
