[QUOTE="Ampdog, post: 857553, member: 144"] Hi Jonesy! As far as I (we) know, Schalk is still himself. We would undoubtly have heard if anything was the matter, seeing as how the man is popular over here. But I will inquire and post here. Schalk is well known for meticulous attention to his clients, so it is uncharacteristic that you cannot get hold of him. As PierreM said. Something is a little weird; perhaps the recommended audio place is not geared for valve amplifier testing? Even if he cannot test valves, operational conditions should show whether there is something wrong with the valves. To answer your question in the meantime, perhaps you meant 6N1P for the valve? (6NP1 is not known.) There is a difference in heater voltage - 6N1p requires 6,3V and PCC88 7V. But the latter can be used at lower heater voltage (6,3V) to give lower noise. But in that sense 6N1p would not perform identical to 7DJ8 particularly regarding noise, although the difference would be small, if noticable. That a preliminary reply. I am not familiar with the Whisper although the pre-amp is well-known around here. Let me try find out about Schalk. Sorry for your disappointment. I am sure a solution will be found. [/QUOTE]
