Hello Everybody !

Do you know if it is possible to find the service manual of the PROTON AP-1000 preamplifier.

Thanks a lot.

What's the problem with this Taiwan-based preamp???Personally I do have a Proton integrated amp,AM455.

There is no problem... for the moment.
I just want to keep it in a good state.

 

[Leolabs]

Are you partnering it with a Proton power amp too????

For he moment i don't use it.
A friend give me this Pream witch was broken. I repair it and now i would like to have the schematic to see if it's possible to improve it.
