Thanks Peter :smile:

I am seriously starting to think to a 6581 and red led version.

Really great job man! :thumbsup:

I am starting to desire the .BRD files.

Do you will share them?

P.S.

Do you fixed the problem of the encoders?

You are welcome :smile:

I hope that the hum disappeares

Have a nice weekend you to

SID powers

Vdd 9 / 12 V

Vcc 5 V

anyway the ground is common with core so probably 5 V can influence 9V

The caps are in parallel 2 x 2200uF ( 4400 uF )

usually I use "larger" capacitors for

" large " current power supply so I think that only 2200 uF it is not enough for 3Amps... when you start to need more amperes a little capacitor may cause ripple.

try enhancing capacitors value.

( to reduce RS use two caps instead of one bigger for example : two 2200uF instead of one 4700uF)

I used two low RS 2200uF 35 V Nichicon capacitors ( total of 4400 uF )

[PowerSupply]

Not really relevant as I made the first test with computer loudspeakers.

I heard no hum...only the classical SID noise.

I will advice you as I will test with a serious audio setup.

OK now is clear :)

It is strange as you used modern el-parts.

may the crowbar section insert some noise ?

This is the first time I use it in my linear supply ( usually I trust in 78xx ).

Peter,

I dont understand ; do you have noise with C64 PSU or with this new PSU?

Yes I have an old C64 PSU for comparison but I will be able to do the test when I will finish the MB6582.

Antonio

[MB6582 Supply]

Yes....

if you make me think about ...seems that

I see something like here in the forum

Hi Rosh,

Is it the Wilba PCB or .....where do you get it please?

[Ebony MBSEQ V4 installed below keyboard]

I think it is going to be a great sequencer

I like this "wide" layout

[Ebony MBSEQ V4 installed below keyboard]

Nice work Hawkeye, :thumbsup:

But it seems to me you have to sand it yet

I see some saw trace in the wood that can ruin the final effect of your work.

:super: A little more sanding ... :sweat: a little sweat and great satisfaction
