Default A good idea is to avoid electrolitic units...go to non polarized

and you will be free of toubles related voltage..then use the one you want, the size you want, the type you want.

Carlos

Default I have images of several capacitors if you want

To make your life easier to identify them.

I am preparing the Dx Supply to the Dx Super A triple.... a third channel will be used with an active low pass filter...so... a third channel only for subwoofer.

You see i am already assembling the pcboards... i will be waiting new electrolitic arrive from Dudainc (USA) as i will receive an entire box having 40 units ... a gift from Evette and Dudainc.

These capacitors (picture) are all made using plastic film... polietilene, poliestirene, Mylar and other materials... they all sound the same, some of them have a little bit more distortion than others, but you cannot listen the distortion as the level is too much low...so, it exist but cannot bother you.

Dx Supply (under construction but already tested... search for the thread about) is shown using temporary condensers... as soon i receive new ones i will replace the smaller ones, the big one is 10000uf... the ones i will receive gonna be 4700uf/63V

Here you have Dx Supply thread:

Dx Supply, output adjustable, stabilized power supply

regards,

Carlos

Default I have read a lot about capacitors

And i came to a conclusion... two images explains what i concluded.

One that you can find a fake one...the other is your choice.

They are not that different and not that important the selection os types.

Carlos

Default DX Blame ST Super A SANKEN Version

Uncle Charlie,

My DX Super A SANKEN version is now singing...... and all i can say is WOOOOOOWWWWWW!!!!..... i'm very happy about the quality...
So far I'm currently playing with low voltage only using my voltage transformer but high current 12-0-12VAC/30Amps. but this amp still works with very very fine in high and low frequency, i like the base soo much... but so far i did not set the bias as i'm not sure what is the correct bias using this low voltage.
But tommorow i connect to 40-0-40VDC/600VA and adjust the bias accordingly as getting late now in my place....

My dear Uncle Charlie and my freind dear Juan, Thank you soo much guys for all the effort that you have contributed and sharing this another wonderful amplifier...

More power for both of you....

Regards,
Wiljj78

Default Thanks by the more power for us dear Wiljj78

I am glad you like it.

If you dislike the heat, then remove zener and readjust bias to 90 miliamperes.

Juan internet is down....but i am sure he will read soon and will feel good like me.

regards,

Carlos

Default The amp is very cold

With 10R/10W in +/- rail all components are very cold like the amp is not powered, but the sound is very clean and crystal clear using my ipod nano, sound quality doesn't need tone control to blend as it sound like it's already has tone control and completely blended perfectly from my taste.
Anyway right now I can’t play in full power, but I will do that tomorrow using the correct supply voltage and will update you.

Regards,
Wiljj78

Default Thanks Juan....

I'm enjoying right now damn.... I can’t imagine how this amp produce this quality even in a low voltage, the base is really hard punchy, now I prove what Uncle Charlie is saying and he is right this amp has a lot of power and it convince me now to trash my existing amps. Hahahaha…
Now I’m planning to build 3 more channels on the coming months to replace my existing 4 channel modules… Guys this is the best amp i ever build and this is the one what I look for……

Regards,
Wiljj78
