Useful for me! Thanks a lot!
Actually I do not see the Pre-Amp schematic there. Anyone has it? I see OpAmps on socket, looks DIY-friendly.
I also plan on changing the capacitors on signal path.

I have same amp too. And done cap mode. But will have to chage a little. Iv used quite big size caps and had to moove them guite far away from original place. It has noise hier then it was, a believe from long lead connections to the caps. Pre amp section is decrete, opa amps you see are for convertion from single end inputs to balanced and opa amps not too bad there. It has some elektrolitics there so need to investigate if there is some on signal path.
Looking at the schematics, all available parts. I got plenty of C5200/A1943, maybe I can build it one day, just for fun. It will need massive heatsings for sure.
Hi
Have you looked at this pages?
JungSonJA88D-09
Duro
My son have the Duro at the moment and the sound is quite good I would say after a short listening test. Some 100Hz coming through the speakers could be somewhat annoying at times, especially on speakers with high sensitivity.

I have something that looks like other version of this same amp. It has no pre-out in the back, however the holes are there, just with black tape over them.
And when i open it up, the PCBs for input looks different from what i see in the danish webpage linked in previous post.
Anyone knows if its possible to find schematics for this model that i have, or if it is possible to ad the preout also on mine?
I would like Pre out, and also a direct pass to the amplifier so that it can be used as a power amplifier, bypassing the preamp.
anyone have ideas here?

I have a Jungson JA-88D on the bench right now with a fault in the switching section of the preamp. I've looked everywhere and it seems there are no schematics available, apart from the power amp section.
If I could at least obtain schematics for the preamp section, I can probably get something working for my client.
Can anyone assist with a full set of schematics?

Thank you, but the link refers only to the output stage of the JA-88D. I require schematics for the preamp/logic systems.
