Excellent! Thanks to all.

I'll let you know how I get on

i got busy with MS paint and annotated another pic - should make it a bit clearer.

After a couple of hours of listening, I agree with you. The first impression I got was a cleaner sound, more defined and it was confirmed track after track. Nothing extraordinary, but noticeable. It's always difficult to judge when you already know that something has changed, you can easily hear what you're expecting, real or not. But I'm quite sure that bass frequencies are improved, not in extension, but they're tighter and faster. Voices are very good and improved in clarity. I'm not satisfied with high frequencies. They seems to be more shrilling. I've a system in this moment that suffers in the high registry due to Aikido preamp in the making and I've noticed something worst in sibilants and cymbals for example. But with my previous commercial pre the highs were too soft, so I can't really judge it, maybe they're right now.

Massimo - actually the highs on my Shiga were a bit over the top when I first connected this up - after a while things calmed down - my de-coupling caps were brand new so took a while to burn in - remember they are across the important +5v supply in the player so some swapping might be needed once burned in.

are your caps new maybe?

You are being such a great help.

I find the text difficult to read in the MS paint rendering.

Could you enlarge the script size?

Thanks

I understand. I didn't think about it. I'll judge it again in a few days.

Ed - you should be able to read it if you enlarge the pic fully by clicking on the bottom LH corner - after the first click - in the icon thingy.

I'm just wondering if there is a cd door switch that I can salvage from the JVC boombox ?

I'll replace it eventually, I just want to get it up and running first.

[woodturner-fran]

Merlin, yes there is. Its a normally closed type if you are salvaging from something else.

The one from the JVC is in the door frame, has 2 wires that go back to a white push on connector that connects to the pcb under the mech.

I think its around the corner from the where the power supply goes in.

Ok, thanks. I'll pull it out of the boombox.

Where is that (i think 4.7uf ) bypass capacitor supposed to go?

Thanks,
