| Four Hour Tube Amp Warm-Up All tube amplifiers sound OK after 30 minutes. But if you listen carefully sound is getting better during 2-3 hours. Especially it is true for not feedback circuits. I also paid attention that this difference gets bigger after I tweaked and improv... | |
| Four Hour Tube Amp Warm-Up My 300B SET amplifier also sounds it best after 3-4 warm-up hours. After 1.5-2 hours it sounds not bad but not as magical smooth and clear as after 3-4 hours. When I had transistor amplifier Plinius 8200 integrated it was always on. Without coup... | |
| When were the best tube amps made? Hi @larryi , What kind of power supply capacitors did Western Electric use in 59A amplifier? I'm not sure it was already the mass production of electrolytic capacitor then. So probably they used oil capacitors with paper and foil. This capacitors... | |
| When were the best tube amps made? When I had Spendor 2/3 speakers I liked these speakers in combination with McIntosh MC30 monoblocks from 1950x. Than I moved on to high sensitive speakers Altec 604E I recognised that 30 Watt push-pull is too rough for such speakers. I decided to... | |
| When were the best tube amps made? I think it depends what kind of tube amplifiers. The are number of types: 1. Low power SET under 10 watt - 45, 2A3, 300B, PX25, AD1,... 2. High power SET over 10 watt - 211, 845,... 3. Small push-pull up to 20 watt - EL84, 6V6,... 4. Mid powe... | |
| Warbling on horns, piano and vocals It can be turntable mechanics conditions issue - motor, idler or springs. | |
| Outlet - Shunyata vs Hubble 20 amp I like Furutech AC FPX-Cu. Great value for money! | |
| SUT - electrical theory and practical experience Hi @atmasphere , I have a question for you regarding the use of feedback in tube phonostage. Unlike a power amplifier, the frequency response of the RIAA implies a deeper feedback at high frequencies. Is this kind of feedback deep enough to work ... | |
| SUT - electrical theory and practical experience Hi @pindac , I’m agree that EAR834p has rich and bloat the lowest frequencies character. This character of the schematic remained despite improving bass resolution and dynamics, and more clean and open height frequencies in the better implemented... | |
| SUT - electrical theory and practical experience Hi @rauliruegas , Yes I use these Tamura SUT with box build by myself without switches. All wires are directly soldered to RCA. But I thinking to built a new box for my DIY phonostage where I want to place SUTs near input tubes. So I can rid of... | |
| SUT - electrical theory and practical experience Hi @pindac , I had the original EAR 834. I like it but I saw it was built with very cheap components and power supply. Romy The Cat article "End Of Live Phonostage" inspired me to build my DIY EAR 834 with better parts (including air capacitors, ... |
