interesting. Looks like I have a bunch. wanna trade for pair of 1830?

Sure, I can even add one RTX. ;-)

I am awaiting delivery if the JVC Boombox. Idle hands could be a dangerous thing ! I have butchered an old Sanyo Boombox as a peek inside led me to believe that the same chips might have been in it. They are not, but the transport is easily detachable and a search for a data sheet, gave me the pin outs of the chip.

There is a dig out at pin 43 and a 16.9344 output pin at pin 58. I connect to which pin and ground ? There is another pin designated (Digital Filtering D/A Converter interface) I assume I ignore this ?

can someone tell me how wide and high is the pcb that holds the lcd display from the jvc?

The EZ31 pcb is 200mm x 50mm..

Thanks for the goods Peter - payment sent.

Would it be possible to post a quick sketch of how to wire up the digital output/resistors combo.? I have studied the pictures already here but I still have brain fog

Many thanks!

P.S. Audio1st, just want to say I LOVE your Shigaclone - looks absolutely fantastic! I don't suppose you'd consider sharing any of your secrets would you? That wooden plinth is stunning! Thanks.

Any chance to cut some of that PCB away, and still keep it functional? What are the 2 pushbuttons to the left of the display for?

As I was working recently on a new display board, here's the actual schematic, the one in service manual is not exactly accurate.

I also simplified it for my needs, with only 4 main buttons. The other 2 buttons are for programming and repeat. I only need them on remote.

The digital output resistors are also explaned there.

And that's how I implemented new display panel, the wires run through the hole in the bamboo platform (back to front).

The power to LED is taken right after rectifiers (for 18V I find 4k resistor about right)

I still need to find spot for remote receiver.

I placed it behind display window and it works from 2 feet, but for longer distance it's no good.
