It wasn't shiga fault! It works well.

That's why I try to change only one thing at a time.

Speaking of which, a short time ago I replaced the capacitors as per the okapi-pdf.
From the beginning I was planning to go the lowest-cost way possible with the Shigaclone project. Since I have access to some surplus components at work, that is not too difficult. It excludes esoteric caps (like BG), but IMO standard stuff of industrial quality goes 95% of the way anyway.
I'm really not willing to pay big bucks for a marginal improvement. You may or may not agree with this statement, but through the Shigaclone project I found out that my hearing is not really capable of detecting minute changes in sound quality (that may in part be caused by the fact that I continuously ask myself if I'm really hearing changes or just imagining them). What my hearing does seem very sensitive of is changes in musicality and I've found some "improvements" to degrade this aspect of sound reproduction.
Most of the caps I replaced with the well known light blue ones (was Philips, is now BC/Vishay), for the smaller values I used MKT. My first impression from cold was a slight improvement in musicality, now that they're burned in a bit more, this first impression seems to hold. Lately I've been listening to a lot of old school rock music (e.g. AC/DC's Highway to Hell) which IMO is great for hearing PRaT, and the Shigaclone simply excels at it!

Yeah, but sometimes the temptation is just too big to resist. I know I broke that rule by replacing all necessary caps in one go...

Most of those caps are not really needed to be replaced. Presently, I replace only 2 caps, as mentioned here: http://www.diyaudio.com/forums/showt...38#post1671038

Need ideas how to solve "door" switch!

I am finished with box now. Even went back to original JVC trafo how I could make everything compact in single box, except that "door" switch.

Anybody?

Use any switch that is normally closed. I'm using those:

Thank you Daniel. It is not a question what type of switch then mechanical solution how my wife could change CDs easy

I have plenty options od differents switch types to choose from, just out of ideas how to implement.
From the beginning my idea was to put dark glass on the top as movable cover wich would push that switch. However this is not finished yet cause can't find proper hinges.


P.S.
Peter, well, this is a good time to say "Thank you" for share this project with world. Besides that two small words which were written here number of times, I believe that the greatest satisfaction for you is the number of successfully finished shigaclones.
I am proud that mine is one of them. Tnx!

Yes, I was aware of that, but I liked the fact that okapi used much smaller capacitances than the original ones. Plus I don't have particular good experiences with Chinese caps when it comes to longevity. I might even replace the others with the same values of BC/Vishay too, just for peace of mind...
