Dear All
Little did I know - or expect - that my plea for help would give rise a discussion about ... ethics! I will not say I am among the angels, still it never occurred to me to 'fudge' issues and hide my responsibility ... least of all from myself. Something, finally, about 'conscience' (remember that fellow? ... comes through town from time to time!)
Regarding the fuse question ... well, sure, the good old law of not poking about in the innards of the device is golden. However, that 'we' - and I mean the average incompetent - continue to do so is easily explainable. Look at the number of reviews, the publicity, the discusssion on the fora, of the 'upgrade fuses' ... and it is easy to understand why changing a fuse seems very much like changing an interconnect! Plug it in and listen! (By the way: I have implemented these fuses in other equipment and have on each occasion registered an improvement ... cross my heart.) Presently, the BCD-1 is playing music, all the functions seem to be working, but the apparatus is 'stuck' in a permanent 'black-out' as regards the display. As I noted in my response to SRB above, replacing the original fuse does nothing to alter the situtation --- and the sound with the HiFi Tuning fuse is superior ! I am hoping that James and Mike can find the solution, and my thanks to them come what may.
