The earlier Trough-Line tuners are not particularly sensitive in comparison to new tuners, so excellent aerials are needed to provide enough signal to achieve full quieting. I am fairly happy with it. For many years the Trough-Line tuner range was a half forgotten product of a by-gone age, until audio enthusiasts and some designers began to rediscover them. Valve complement changed slightly with the above mention functional changes also adding greatly to the usability of the tuner. Rear of the Trough-Line 2. Leak were a head of their time. It never once occurred to me that there might be more than one dodgy component.

With the third cap that I sprayed, I hit the jackpot - I'll never forget the moment that the white noise turned into the theme tune from 'The Archers'. I suppose its worth remembering that this was the early days of solid state. The aerial connection is still via screw connectors and having an on board stereo decoder the multiplex output is gone and audio out is via 2 fixed audio leads terminated with phono plugs. At one time we had a waiting list of nearly 40 customers as they were so obviously superior to all but the most exotic of American tuners such as McIntosh, Marantz or Fisher. Apparently they found it very hard to get the same level of performance technically from it as they did from the valve designs. Sleeve came with unit at time of purchase and is an original owner addition and not a Leak sleeve. Give me the warm, solid, beefy tube job anytime.

LEAK TROUGH

I was told that he would spray some very very cold stuff on each cap in turn, until the unit magically got back on tune. Many Trough-Line tuners were used in cabinets, joint cases with a pre-amplifier as opposed to standalone units. This was done via a single long screw Custom made oak wood sleeve made for the Trough-Line 3. Audio out was via a single fixed cable terminated with a phono plug and aerial connection was via screws In 1964 the Trough-Line 2 was phased out for the Trough-Line 3 which adopted a new visual style. Put one up against the latest all singing, all dancing exotica and the Troughline would win hands down. You can see in the pictures below how I did this.

However this change introduced a problem at the calibration stage. Last edited by Spectral Morn; 21-07-2010 at 17:35. Silver and black was now the order of the day with the passing of the Art Deco style of earlier models I feel something was lost, at least from a visual stand point. Audio output is now via 2 rca sockets. Rose tinting and the rush to buy all the Troughline's around, means that the Stereofetic has been forgotten except to the faithful it doesn't have valves so can't be any good an it? Rear view showing metal upright for screwing the tuner inner to the sleeve. Black Ash wood stain was used from Cuprinol to bring it back to a nice state of finish. Thank You had an original wood sleeve that needed some restoration.

Regards D S D L Last edited by Spectral Morn; 20-05-2009 at 09:11. The process took two days as I tried to build the layers up without running. Every other design on the 1950's market had to be powered via a power outlet on a pre-amplifier or power amplifier. However many were supplied with wood sleeves and later with the Stereo a metal sleeve; this allows the units to be used sitting freely safely on a sideboard or on a Hi-Fi rack. If the plating or solder was off then the Q of the oscillator trough would be off and influence the performance for the worse. However gain levels must be carefully judged to avoid overloading the tuner.

This would locate the faulty component, which could be simply changed. Anyway, after two weeks the bloody thing never shifted off-tune once! In the centre of the trough, a conductor ran along the length, with various taps that connected into the circuit of the oscillator valve and tuning capacitor. Chris I didn't know that was an oak sleeve. The unit was stylish but very bulky and heavy,this was due to the use of copper in the trough. Note the Multiplex output socket on the right.

It would appear Leak offered 2 sleeve choices, wood and metal. At one stage we did try the Stereofetic but it really wasn't the same thing at all being thin, flat and uninvolving. So I put some white insulating tape on the cap so it could be found again easily. The metal rectangular box mounted on the inner side houses the new Motorolo stereo decoder. The Trough-Line 3 and Stereo co-existed with the older design at lower cost £32 and the newer model as the more high-end model, at higher cost £47.

Is the Trough-Line as good as has been claimed. The rear of this unit has been owner modified. The addition of 4 rubber feet completed the cosmetic restoration. Being self powered also makes the Trough-Line ideal for purchase today. These changes are important as they make the Trough-Line into a tuner that can be and is well suited to modern use. I have never heard a Stereofetic, but they are never mentioned by Radio fans or Audio Magazines so I must assume perhaps wrongly that they are not very good, in comparison to the earlier valve tuners.

It was this design solution that gave the Leak tuner its distinctive name, the Trough-Line. I don't know if this was normal or not as this is the first time I have seen this. Leak did not want to change the Foster-Seeley discriminator and it was this that limited bandwidth. All of these were overshadowed by the Japanese onslaught in the 1970's and Rank took Leak over and killed it. Each unit had to be measured to insure that the oscillator voltage was correct and only then could alignment happen. The 3 continued to offer a multiplex output for hooking up to a stereo decoder, however this was about to change with the introduction of the Trough-Line Stereo in 1966. Re-furb'd, rebuilt, stereo, mono or simply working.
