Dalesford were a small company specialising mainly in drive units based in Pudsey near Leeds up to 1983 when they ceased trading. There were copies made in the U.S.A. marketed under the name of Cambridge/Dalesford owned by Mission? some were sold by A&S speakers
There seems to be very little info available about them but many of their drivers bared a slight resemblance to some of the Kef units like the 8" was very similar to the B200A and the D30/110 very similar to the B110 5" unit. Both the Kef units whilst they were in production were tauted as suitable replacements they worked reasonably well without too much attention being needed to the existing crossover.
Certes, c'est sympa mais rien ne vaut un bon ampli à transistors, surtout à Mosfet's
