Dear All, With my British "hat" on, I should like to advocate a British substitute for "The Packburn". This was originally called "The Mousetrap", but is currently called "The Front End", and has several practical advantages over the "Packburn". (1) It still has the "archivally-valid" advantage of choosing the quieter of the two groove walls at any instant, so it reduces the surface-noise while not touching the wanted sound. (2) The pickup preamplifier precedes this part of the circuitry, so a nest of interconnections to get a Packburn running for lateral or vertically modulated grooves is not needed. (3) I have been told how the "Front End" achieves better results than the Packburn, but I'm afraid this is a trade secret which I must keep. But the result is considerably better than the Packburn. The sliding low-pass filter features of the Packburn are not incorporated. (4) But declickers analagous to those on the Packburn are included, two devices working with high frequences and low frequencies. But personally, I prefer to follow the "Front End" with a CEDAR declicker. (5) The "Front End" also incorporates three variable-turnover equalisation circuits for all the standard equalisation curves known to myself as a British disc engineer, so the disc may be equalised in the same box, and subjective judgements of declicking optimised. So high-level equalisation is therefore unnecessary, and it is not necessary to combine it with a phono pre-amplifier. Peter Copeland

Thank you for the answers.
I would like to do both. Listening to the 78s and transfer them to DAT.
Cleaning records and different sizes of styli are not the problems for me. I have twenty-three styli (both conical and elliptical) and a Nitty Gritty model 2.5 Fi MKII.
I will try to play the records in stereo.
I wouldn't like to use any computer. "Computers were never designed with music in mind." Roger Beardsley
Have somebody experiences with the Packburn reducer
Yours sincerely, Otto Striebel

Hello Otto,
I suppose the first question I have is: What is the end product of your playback of the records? In other words, are you just listening to the 78's in real time, or do want to copy them and clean them up to final digital or magnetic analogue copies?
If it's in real time, the clean up tools are different than if you are digitizing to a computerized program.
