ahhh I see,
If it's ok without I'll see how bright it is and drop a resistor in if it's blinding

cheers

With the EZ51 the display board is shorter than that for the EZ31 so never needed to be shortened for easier mounting. The pot as far as I can remember, (like you I may have read somewhere but there was a lot of reading was just so that the LED brightness could be reduced if wanted. led's generally operate off 5V so as long as the LED gets it's 5V, +ve to +ve all will be well. The original mod file in pdf format showed a connection to the power supply... which probably simply used a small resistor to drop 8V to 5V.

I have the 51 one and haven't shortened mine. I believe if I remember correctly that 680R was the recommended value - but do as you like on this one but remember that it draws unnessesary current from the main board if you go for full brightness...

cheers trevor,
feel a bit more confident about it now, don't like unexpected wires about the place.
Funny thing happened when I opened up the EZ51, I was looking at a metal chassis inside and for 5 minutes I thought I'd bought the wrong one, the chassis was so different.
Turns out I was studying the cassette chassis, don't you just feel like a fool

Thumbs up Transport tweaking...

Made the transport and have more or less been tweaking/voicing it for over year. Here are my findings (so far, things may change ). Hope it helps someone.

Kiitos kaveri!

Yes, thanks. I have just started my shigaclone journey and welcome your input.
To begin with I'm still try to figure out what DAC to use so meanwhile I will use the analog output from the thing... Of course I will move to digital out later on.

Dear Peter.
When indtaling v-cap or an audio note, Jensen, duelund. Do I still mount in the + and ground? It looks like you only have one leg in ground, what about the + . Could you show a photo from the other side. Best Kris

Hi, listened to the as yet naked Shig again last night and I swear it's getting better especially female vocal.
Anyway as other makes have said the motor is quite noisy and it has a definite metal to metal ring to it.
Does anyone think that it may quieten down if a rubber spacer was inserted under the two mounting screws to isolate the outer casing from the metal chassis.

Hello all.
im hoping someone can help- i was given a part finished shigaclone by one of my customers early this year and im just now looking at it and trying to get my head around it.
it has a 24v transformer and a PS which appears to be deisgned following the schematic on this thread- The CD Transport with the exception of the regulator being LM317. they are housed in a wooden cigar box, and i did find out through some googling that this may mean the original maker possibly wasnt competent!

the PS does work and gives up to 24v output by adjusting the trimmer, however with the votage set correctly and connected to the transport the display just flashes "00" once and nothing else happens.
checking the voltage shows that it drops down around 2-3v with the load, even setting the PS output to 18v only gives 4v under load. the transformer outputs read 24v ac regardless.

the transport its self has also been modified as shown in the above thread, but in addition to the 5 components being removed also has c942 removed, as well as 2 cmt components which are next to it.

if anyone has any ideas id appreciate it.
Many thanks,
Russ.

If you are referring to this picture: Finally, an affordable CD Transport: the Shigaclone story I connected one lead to ground, the other lead underneath the board to closest trace, which was more convenient than placing both cap ends into original (electrolytic) footprint.
