Hello and welcome to the Carver forum, carlton8000. Yes, as mentioned, all of the parts can be still had. That said, the woofers have gone up dramatically in price within the past couple of years but the good news is that they are still available. Rolland can rebuild or upgrade the crossovers, Dynavox has the woofers and DaveS [here at the forum] is the same cat that rebuilt and repaired the ribbons while the Carver corporation was still in business. We also have folks that can assist with modifications, custom tweaks, setup, refinishing and whatever else may strike your fancy.
I take it that you already know that the Original Amazings only have a handful of amplifiers that can properly power them, correct? The Silvers and the Plat's are much more efficient, which opens up the range of amplification to drive said speakers. Right now, the prices of Carver gear have shot up....just due to the season but if you are patient, we can assist in finding you what you want at a price point that won't break the bank.
Anyhoo, welcome [again] to the forum and we hope you enjoy it as much as we do.
