Jolida 202a mods

Hi,if it were mine I would send it to one of 2 places.There is Underwood HiFI he sells new Jolida and new modded Jolida.They also upgrade Jolida products.I think the guy who ran Sonic Frontiers does the mods.There is also Response Audio in western NY they are know for there line of modded amps.But they should mod Jolida also.Underwood can be contacted on Audiogon he sells here.Thats it for me.KP

Thanks for the response. I am actually an electrical engineer and really don't want to pay the shipping and labor to have someone do what I can do for free. I am just looking for a parts list and schematics. I got this amp for a great price, but I don't want to pay upwards of $500.00 to have someone else do the mods.
Thanks
