Also critical when planning for a low power amplifier is to know in advance what speakers you will want to drive with them. It goes without saying that speaker efficiency and speaker impedance are of prime importance.
Say a fella wants to build an SET monoblock based on the 300B..
Could you point him in the right direction or where to start. I see a kit on ebay but not sure if that's legit or not. I don't own the speakers yet and plan on building my own that would pair up well with the amp. Any help appreciated.
