Dear Cat,
It is not de de grounding problem.... my preamp is working well on 8000A (without internal separate to pre & power), for 8000A, in order to fully release its power, we need to separte it internally.
My problem is that when i use the (internal spearted 8000A), my preamp casing act like a mic, whatever sound u make on the preamp casing will be transfer to the speaker through the power amp.
Most probably is the problem of 8000A after internal separation.
Spell,
Ha... learning modification & DIy need to pay for lesson at initial stage, most probably may spoil some PCB especially those china made product...
anyway it is a good start.
I personally suggest not to spend much to modify the CD33 since this player not reliable, the more u modify more problem will come, you may really vomit bloood. If want to mod, better mod the MF A3 and a a tube buffer after the DAC. |
