Hi Ricardo

Glad to see you sorted the problem and can hear improvements. The mounting pcb looks nice too.

The 14V on the opamp output would most likely have been a missing -14V as Lee said.

Hi Brent

The sound is so much more detailed with this mod... Now I start to understand the possibilities of a discrete output.

I was having a bad contact in the -15v to the left opamp... Now everything is smooth again.

Thank you for all the help and support.

Ricardo

Hi

I still have a small issue..... The remote only works if pointed at less than one inch from the sensor in the CDP.

I do not know what started this but it is like that for a couple of month now.

What should I do to correct this ?

Another question rose .... How does the volume control work ? Does it keep all the information of the CD ?

I seem to notice a better sound and better STN ratio when the volume is 100%.

Regards

Ricardo

Change batteries in the handset ?

The volume control works in the digital domain by reducing the amount of bits - therefore it's useless. Keep it at 100% and enjoy the music.

LOL @ AVR300

Yes the volume on the 63 should never be used it's awful.

Also check the 5V to the front panel, if this is low then the sensor will be less sensitive as would the transmitter if the remote batts were flat.

You must admit, it would be a pretty good reason and easy to fix.

Default Ricardo the TX behind the mechanism?

How is that thing secured in place? I've thought of mounting a tranny there but been stumped as how to secure it and don't want to just rely on friction and inertia.

Also a public thanks to Brent for cleaning up my C1.

Hot glue works well. I've also used silicone which was ok too, just had to wait for it to set.
