Joining...

My current mods (unfinished):

Onkyo SE-90PCI (all capacitors except the OS-CON removed)...


I will use the BlackGate F Series & NX Hi-Q, Vishay S102 & Holco resistor, and SideRealKap (all on the way, expect to arrive today). Available parts are Elna Cerafine, Rubycon ZL, and ZA.







My previous project:

Altec MX5021:
Supply capacitors replaced with oversized one.


The coupling capacitors replaced. The opamp modified with socket and OPA2134PA.


The new XO with Solen for the high pass and cheapo polyprop capacitor for the low pass. Rewired with Canare cables (not shown).

Toshiba SD-2960 DVD Player:
D/A coupling and supply capacitor replaced.


Switching PSU capacitor replaced.


Just another shoot


I will try to change the main caps with 4x22uF/630V Solen to see the different... I don't believe in switching PSU, but this time, I will give it a try... also the Vishay SF5407 diode will replace the standard IN4007...

Just finished my Onkyo SE-90PCI mod...

Yes.............
Haven't tried it yet... later lah.. dont have time... I finished around 10pm yesterday...

Here's is the list:

* BlackGate F Series in main supply.
* Rubycon ZL in DAC supply (upgraded from 330uF to 470uF)
* Elna RBP2 in op-amp supply
* BlackGate NX Hi-Q in DAC->op-amp coupling
* SideRealKap in op-amp->output coupling
* Some Rubycon ZA and Elna Cerafine (non-polar) in other sections

I may take 2 PCI slots I guess...

Those caps surely need break-in time... I havent change the op-amp... want to make sure the sonic characteristic first (I changed too many caps, cant figure out the result, could be good, could be bad...)

Wazzzzuppp ijan?

Overkill?
Perhaps... but that didnt cost too much... ZL is very affordable... and so does Cerafine... the BlackGate F Series also quite cheap (it's an old stock stuff)... the 10uF SideReal Cap also very cheap (again it's my old stock stuff)... it costs me no more than 3.3uF Auricap...

It looked overkill... but actually... it's quite affordable eheheh...

10uF SideReal around $20 I guess... mine is old stock...

My last Aikido project...

Complete parts before connected...


Some combination in the components...


Well, the potentiometer and the output caps for driving my 32 Ohm Grado headphone...


Project on testing... 6N1P+6N6P and 5U4C rectifier...


The 6N6P... Russian, high power tube...


The DIY "monster" transformer... 300V-CT-300V/100mA (B+), 5V-CT-5V/3A (filament), 5V/3A (rectifier)... Completely oversized wire... the 3A rating is minimum, should be ok to be pushed into 5A (no voltage drop so far), still around 5.1-5.4VAC tested on 3A load...


Another shot from another side...


Rectifier changed to 5U3C/5U4GB... Even better sound...
