It is a lot of money BUT if you already have a KI and like it but you have say £1500 to spend on a new player and you have no clue about modding then I think its good.
For us its a rip off.
I would think that KI TZG is better than a £1500 new player.
You could buy a KI off ebay for £150 and send it to them if your joe blogs off the street.
Also its good to see we are on the right lines with these mods too.

...do you have an updated mod-list for a CD67SE as well?
yours,
mickie
Not got one for cd67 mate.
All mods in 63 can be applied to 67. Lots of the circuit are identical.
Ray is the one to ask on the 67
Just ask and we will try to help
I will be updating my 63 list soon!!!

Not yet.....lol
been to busy at work!
also not sure what value to use on r1 yet.
Ray if you have some good advice its welcome.
I specialise in lots of areas of electronics but im not major in dc ripple and its filtering.
What I have come up with is my own idea but am unsure of exact values without spending ages with scope.

Please correct me if I am wrong Andy. Do you care to share your schematic?

Allan,
I found this website very useful!
http://tangentsoft.net/elec/opamp-linreg.html
I think AD825 is used most often as the op amp.
It's probably used for a number of reasons, and one being the fact that if you are also building op amp modules you can bulk buy AD825!
