| [#2] Fourier Triomphe OTL amp Bought from Excel more than a decade a decade ago. Stereo amp employing 16 6AS7 Sovtek coke bottle tubes (i.e. 8 per channel). Toroidal mains transformer. Unstable amp and had to be fixed by technician couple of times in less than a year. Technician told that unsatisfactory data shown on scope measurements. Sound quality is no match for Futterman OTLs, such as H3aa and OTL3. It was then sold. |

| [#6] Fourier Triomphe OTL amp I have read a lot of these OTL amps and wanted to know how they perform, seems Fourier May not be the best OTL in the market? and OTL should mate with Electroststic speaker the best? |

| [#7] Fourier Triomphe OTL amp Not necessarily electrostatic speakers such as Quad ESL such as 57 or 63 which I tried to go with Fourier and Futterman OTLs. OTLs go well with any high impedance speakers, readily available are 16 ohm speakers. Got Falcon LS3/5a of 15 ohm of current production than those aged vintage likely with inherent issues . Falcon sounds great to mate with Luxman MQ36 OTL and other transistor amps such as Onix OA21s. 6C33C is one of the most common tube used in recent OTLs but personally don't quite like the sound which is one the bright and fast side. 6LF6 is the best tube in any OTL amps I have heard. 6336A twin triode used in Luxman MQ36 sounds almost on par. Shortcoming of OTLs is they run really hot. They have to be stored away during summer time. Can only play from now until April next year! |
