| What is the best OTL out there? Al,Charles,My OTL uses 8 or 16 ohms full range speakers,I can use 4 ohms but it's too bright,I am building an OTL that I can change the output tubes having 7.5,6.3,5.0 & 4.0 volts filament.My OTL use interstage transformer and only one capaci... | |
| What do the different tube amp types mean? Ralph,The OTL is only using one DHT tube and 2 other tubes,3 tubes total per ch.,Audiophiles are looking for the best sound, just like the Atmas,that you claimed they are the best for the money.Are we looking practicality or sound quality? | |
| What do the different tube amp types mean? notnow2,How did you know that is not practical?I also designed & build one with interchangeable output tube using only one of either VV52B,,300B or KT88.With proper design,you can use any power tube to make an OTL. | |
| What is the best OTL out there? How can you be sure,I build and designed these types of OTL and they sound excellent.using KT120,KT88,VVT52b,300bMaybe you are just concentrated on your OTL. | |
| What are the Best FM tuners? It looks like everybody try to push what brand model they have without any comparison.I had owned over 25 tuner SS & tubed and I always come back to tube which they have 3D,transparent and very musical.Bogen,HH Scott & Pilot and one of my... | |
| How does OTL amp get its power? Atmasphere,I have built an OTL that uses any of the 7AC,,KT66 / 6L6 / E235l / 8417 / KT88 base tubes and even 6A3 / 6B4G / VV52B / 825 / 801.& 811.I think there is no limit on whatTUBE to use in an OTL amp.. | |
| How does OTL amp get its power? OTL get's it's power from the total plate dissipation of the paralleled power tubes. | |
| What is the best OTL out there? There's some out there who designed and build their own OTL that uses better tubes like KT88/120/150,,300b,,VV52b,,even 211 / VT 4C can be used and they are more efficient than the ones on the market today. | |
| Question about valves running hours Migueca,If the input voltage is not the same as in the US,It affect the filament voltage and it's not 6.3 volts anymore and that's why tubes have shorter life if they are not rated. | |
| CHINESE tubes? I just don't like to offend a friend that just got a Cary 805 AE and using Chinese branded tubes?Do you think it's about savings? | |
| Where do you guys buy tubes? Ralph,What value of B+?since those tubes you got from the seller, he already applied B+ on them when they were tested.And one more thing about cathode poisoning if you run it for 3 days? | |
| Where do you guys buy tubes? I can buy anywhere as long as the seller guarantee it's tubes on test results on what tester but not on emission test.Pay attention for matched transconductance and plate current.Double triode like 12A( )7,6sn7,ecc88 etc.,they must be matched at ... | |
| Question about valves running hours The heat is develop when the power tube plate dissipates,the more watts the more heat and the more heat the shorter the tube life.A well designed amp should have about 60-70% of total plate dissipation | |
| How do you clean tube pins? 9 pin tubes can be easily clean using wire brush,for octal and 4 pin,I use hair brush,soap and water but be careful not water getting in between glass and the tube base. | |
| How Important is Tube Matching? There are many design of using preamp tubes like 12ax7,ECC88,6SN7 and other double triode tubes.If the design is a cascaded type,you don't need a matched tube but if it's in PP phase splitter,you need a closely matched tube. |
