Post Subject: 230v version coils get hotter than normal after some yearsPosted by Amir on: 12/7/2021
Romy Thanks
I had 6 pure power (230v version) since 2017 and now i have 4 pure power , the first pp3000 was faulty and it has the same problem that some users reported here (GSC) , the output frequency spectrum of first PP3000 had some extra harmonics (i could hear those harmonics in loudspeaker) and the sound was bad. other 5 pure powers were quite healthy without any extra harmonics (no noise in loudspeaker) and also the sound of those 5 units is very very good.i also connected pp3000 to my TV and the picture quality increased .
i have connected 300w (total power of system) class A SET tube power amplifier to my pp3000 and the result was perfect.i have connected 400w (total power of system) class A Push pull solidstate power amplifier to my pp3000 and the result was perfect.i have connected 700w (total power of system) class AB (low bias) solidstate power amplifier to my pp3000 and the result was good but not perfect, pp3000 decreased macro dynamic with small margin. i should say totally the sound is far better than wall AC in all respects but the only critic is macro dynamics reduction.
this PP3000 has been working since 2017 non-stop and the only problem that comes to my mind is the output coils get hotter than normal. i have installed better fans to keep low the coil temperature . it seems the coil of 230v versions are more sensitive (one of my friends had a PP3000 and after a-while the coils burned).
