Yup. I prefer the 'Stereofetic' to the 'Through line 3'

Hi Spendorman,
I also have a pair of Rogers LS 3/6's. There's also a replaced bass unit in mine (Kef B110 I think). I've only every chatted with one other person who owns a pair. I'm in Australia, and that guy is in the US. Beautiful midrange on them hey. I had mine recapped, did you recap yours? considering going back and putting nicer caps.
Pics of mine attached.

Hi Bluetone
That's a KEF B200, not the best replacement for your speakers. The midrange will not be as good as the original units for the LS3/6 or Export Monitor.
I have tried the B200, most versions. The original capacitors in the crossover would most likely have been OK as they are not of the electrolytic type.
I can suggest a couple of things that should improve your speakers.

In my view, the best replacement bass/ mid unit is the Dalesford D100/200. These can be found in 70/80's speakers such as RAM etc. I make a a small adjustment to the crossover that requires two wirewound resistors. The next best unit is the Dalesford D50/200.
The adjustments to the crossover are possibly required because the original LS3/6 bass unit is nominally 15 Ohm, and we are using 8 Ohm units.
Although, it appears that Rogers used the 8 Ohm Dalesford with standard LS3/6 crossovers in the early Export Monitors.
I can supply the crossover mods if you like. I'm not sure if it would be beneficial with the B200 that is in your system. It would likely slightly boost the already coloured midrange of that unit.

Same here and by a very large margin! I really can't see what all the fuss was about with the Troughline. It was probably the best of the British all valve FM tuners and the use of a tuned line local oscillator (the "troughline") gave it excellent frequency stability for the time. In comparison to a modern tuner though it's a non starter....

ok thanks for the tips. I will try to source the Dalesford driver. Out of interest, how does your LS 3/6 compare to your BC1's do you have a preference?
