Conrad johnson premier 140 upgrade Teflon schematics wanted

Post by ghibli.iron »

hi
I was very hesitant about buying a "new" amplifier, I had two choices:
1) conrad johnson premier 12 mono (available in Germany) unfortunately the photos received from the seller I have shown that the two mono have been significantly modified, I decided not to buy it
2) conrad johnson premier 140, in original state, found for sale a few miles from my house.

I listened to the Premier 140 and decided to proceed with the purchase and tomorrow will be in my system at home.

I have read on various forums that the premier 140 improves further by upgrading capacitors with new Teflon capacitors.
Unfortunately ship the amplifier to Conrad Johnson in the United States (Italian assistance has some problems because it
does not respond to the email, I think it was closed) would be too expensive, so the only alternative that I could be to
make the replacement of the capacitors by a good technician Italian providing him the necessary information.
I therefore ask the frequentori forum if anyone has the schematic for this type of upgrade?

thank you very much

We do have the schematics in our database. In terms of what caps to upgrade, I would say only budget is your limit. I guess you could replace them all.
