Glory, Since you have ZU speakers you will not have much advantage in seeking an OTL with more power.
Tenor 75 Wi OTL
Just bought this OTL by Tenor.
Living in Destin FL and owning the Atmasphere S30 amp I could remove some power tubes to reduce the heat in the summer. Can this be done with the Tenor?
Kelly High End in Ca. who I bought from said the amps puts off very little heat after being on for a hour or two. BS from the seller?

The Trancendent is Class AB vs. Class A operation of the Tenor Just FWIW, the math does not support the idea that the Tenor was class A, not if it is also 75 watts output. IME, the tube is difficult to operate in the A2 region due to the prodigious grid currents involved. The amp is class AB1, similar to the Transcendent in this regard. The big difference is the fact that one is pentode and the other is triode. In OTLs that makes more difference than the class of operation, since you are not dealing with zero crossing issues or commutation (switching) of output devices (OTLs tend to be immune to these difficulties). |
A customer of mine has this amp: http://www.atma-sphere.com/products/ma3.html He can run them all day in his room and not be any hotter, even though his home is not air conditioned and he lives in Guatemala! He accomplished this by putting the amps in a specific location in the room, above which are hidden ducts that have a moderately-powered fan at the other end. The heat goes up through the ceiling and out of the house. It is an elegant and simple approach. You can sit in the room all day and be perfectly comfortable. |
