Marantz CD36 lampized with a couple of 6J1b pentode is one of the most refinite and beautiful sounding player I've ever listening at!!!!!
I swapped the main capacitors for a Pana 4700uF and the other one 3300uF and the two caps closest to DAC with Sanyo 1000uF 25V (green ones) ; the first on the 5V supply the second one on Vref pin wich is the one connected at the I/V resistors.
For I/V resistors conversion I used two paralel 1K resistors each channel , one of them was SFR by Philips wishay wich gives great details and accurate image.
I think you can go for Caddok, Dale,Kiwami,Holco or other brand resistors........to please your taste with the best quality!
The 6J1B pentode gives a great quality and they don't ask too much in terms of current or high anodic voltage.
The result is a real analogic masterpiece!!!
CD36 is one of the most analogic player i've ever modified!!!!!!....a pleasure for the ears!!!!!
We have to work with a very low signal in output, equal to 1/4 of his brother TDA1541 , we're talking of 1mA out to be treated without the use of any op-amp!!!
It's funny when I read of some peoples using a simple universal buffer after a TDA1545 without any opamp :D , but more sad looking at people believing them........alas!... what we can do.....this is the world of MARKETING !
This player with 6J1B penthodes, gaves really one of the best result I've ever obtained in a CD Player and gives a tad of satisfaction to the tweaker just 'cause it need an accurate job to sounds such good!!!
