Thanks,
I know about that, but I was lucky up to today
XVII have update probably each week.
When I start modelling I always perform Sync Release and XVII always have something new for me

Thank you, Bob
I design PCB for both MC and MM versions (MC version on picture).
Schematic was heavy modified. Only transconductance amp. with HF Eq. the same.
LF Eq, DC-servo, Output Buffers are different.

Now I waiting for PCB for external power supply.

Hi Blackjack

Very nice build. I see that I would change one thing in the PS. I would wire(s) from the AC LINE (IEC) to the rear of the FUSE HOLDER. This will keep the power disconnected from the fuse when it is removed (No finger contact).

Hello Audio1Man
Thank you for response.

I use BK-HTC-30M. See picture
BK/HTC-30M Eaton | Circuit Protection | DigiKey

It is impossible to accidentally touch side contact with finger when replacing fuse in BK-HTC-30M.
Need at least nail and great desire. There are many others easiest ways for electric shock.

But thank you for suggestion. I will make thus next time for 101% protection.

-- Best Regards,
Victor

Hi Black Jack
Some fuse holders are much better or safer than others. Some have large metal below the plastic, and when removing a good fuse or replacing the fuse the fingers can touch the metal and the fuse contacts the ring while inserting.

Almost all of my designs have needed UL, CSA, VDE & CE, so I always look for the things for human safety. Many persons can earn the Darwin award.
Again a great job.
Duke

 

[Black Jack]

Yes Duke, you are right.
I am really grateful to you for a remark about safe fuse holder wiring.
