Upgrading the by-pass Caps for Aleph 30
This might be old hat for most of you guys but I made a small tweak which made a quantum difference in my DIY amp's sonic performance.
I initially replaced the ERO 1yF cap with a a Theta cap. The tops were stunnly clear and very fast. After one day I tired of the sound and then replaced it with a Sonicap and walla what a total transformation. The midrange and bass definition sounded so much better. It is hard to believe that a single cap can cause such a transformation.
Now if anybody knows how I can get the bass on this amp to sound tighter I would be all ears.
X-mas wishes to all
I'm sorry, but I don't understand which cap you are talking about. Do you mean C8 (10 picoF) or C7 (1 nanoF)?
Bypass caps for Aleph 30
My amp has three by-pass caps per channel on the PSU. I do not have the circuit diagram for the amp and simply replaced what was already soldered on. I suspect it is C8. I also upgraded the C7 but is made the amp to warm (valvy-sounding) for my liking.
I am now wondering what would happen if one upgrades some of the other parts was well. The amp already has a 600 Va transformer and about 60.000 mfd per channel.
Overall I am very impressed with the sound quality.
Ah, thanks for clearing that up for me. I thought you meant any of the feedback caps. I don't think the original PSU has any bypass caps in the schematics.
