Paramount Soft Start Upgrade
This kit is now retired and is no longer available
This mod to the original version of the Paramount 300B/2A3 monoblocks is fairly extensive and brings those amps up to the current v1.1 specification. It removes the existing PC board over the 12AT7 socket, the 12AT7, the nine pin socket and the terminal strips around the 9 pin socket. It will include a new, bigger and slightly more complex PC board with soft start function and the parts to stuff it, heatsinks for the active load power transistors, a new nine pin socket, new standoffs, mounting hardware and t-strips, a new beefier zener string and 5670 tube – all X 2, for the pair of monoblocks.
