[QUOTE="charles, post: 263820, member: 2759"] The 6146 has been used in some audio amplifiers. According to its operating characteristics it is perfectly suitable for audio applications. The 807 can be used as is in a Quad II with some modifications to the wiring as it has an anode top cap anode connection. In the original Williamson Amplifier literature it mentions that the 807 can be substituted for a KT66. The characteristics is more or less the same except that the 807's can operate on a higher anode voltage. Both the the 807 and 6146 are beam tetrodes. I listened to a Quad II with 807's and to me it sounded the same as the KT66's. Both these valves have a limited audio application because of the anode top cap connections. Using such valves they have be covered because of a "open" anode with its dangerous DC voltages. Kind Regards Charles [/QUOTE]
