Well, this is the amplifier I used to draw design diagrams for as a teenager in the mid-1970's, and then dream that I had built it! Unfortunately as the power goes up, the amplifiers become harder to find.

The TL/50 Plus amplifier is shown above is finished in the gold enamel of the earlier models. It is fitted with 6550 output valves, although originally they were mainly shipped with the fabulous Marconi-Osram KT88. Also, the unit above has a rather cheap version of the 5AR4 rectifier, which normally has a slightly bigger and less-rounded envelope. Originally Mullard 5AR4's would have been used.

Even though Leak produced a wide range of power amplifiers, all of them had the same high sensitivity, and the TL/50 Plus is no exception, with just 125mV giving 50 Watts out, with distortion reaching 0.1% at 45 Watts. In reality the amps would clip at just over 60 Watts. Feedback on the TL/50 was slightly lower than other Leak amps at 23dB.

Note that both the TL/25 Plus and the TL/50 Plus had a heat-shield to protect the mains transformer from the radiant heat from the output valves (although advertising shows that the earliset models made seemed to lack this feature). In the TL/50 Plus, a filter choke resides next to the power transformer (not visible due to the heat shield).

Around the time of the introduction of the Leak solid-state amplifiers (circa 1963), all the valve amplifiers changed from gold & brown livery to the grey & silver livery of the solid state amplifiers. A late model TL/50 plus is shown at the right. This unit is fitted with genuine MOV KT88's.

The Leak pre-amp plugs into the black octal socket on the left, and an input gain control and RCA connector are next to this octal socket.

What is the best tube for your TL10?? I have tried both EL33 and KT61 (Osram), and I thought the KT61 is better sound.

I found the TL10 is quite light on the mid, but the extension in the high is pretty good. They do sound more dynamic; but for vocal, I still prefer the KT66 sound.

I tried KT61, 6P25 & EL33.

EL33 較柔
KT61 較剛
6P25 界乎兩者之間

沒有勝負
口味問題
