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?

Glory, congratulations on your system. Sounds like you are having a ball. Have you considered installing central air? A window AC unit?
Glad you've made everything work to keep the sound you love!!! I get some heat also but love the OTL sound so I too find ways to survive. As for the bill it's cheaper than gas or dock fees, at least that's what I tell my wife!!! FWIW she loves the OTL sound and would be sad to see them go!!! Enjoy!!!!
Glory, I am glad this seems to be working out for you. On a further note it seems like these amplifiers throw off new levels of heat considering the power rating, 720 watts per amp!!! I'm not sure this is at full power or just when you turn them on, it wasn't clear but the venting through the fireplace chimney seems like a great solution. The outputs on these babies must be biased REALLY high which might be a big contributor to what you are hearing. I can't imagine what your energy cost might be adding a/c costs to compensate for the heat generated. I know the VZN80 was in the 700 watt range but it is stereo. I was listening in February when the weather is cooler and it REALLY warmed up the room in short time. Ventilation seems the only real practical option, enjoy!
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).
Glory,
You`re quite happy with the wonderful performance of your system, can you leave well enough alone and resist the urge to monkey around with it anymore? LOL.
