PS I just re-checked the ARC web site. The price of the upgrade is $795 plus tubes. It is possible they might not even be willing to upgrade this particular unit, due to the modifications that were done. This is a "what if" question. Thanks, MBonn
Would you re-furbish an old ARC SP3a-1 ?
I have an old (circa 1974) ARC SP3a-1 preamp which basically does not work. It had some "un-documented" modifications done to it about 15 years ago. Is it worth the price to have ARC restore this classic and make it into an SP3c ? (The stated price for the upgrade is about $900, but they may charge more due to the un-documented modifications.) How would this then compare sonically to newer tubed preamps ?
