CTA305

Control amplifier





Production start: 2002


Intended to be at the centre of a high performance audio system, the CTA305 is a flexible control amplifier with five line-level inputs, including a monitor loop, and a built in RIAA circuit accommodating moving magnet and high output moving coil cartridges.


Under its time of production two versions came out.

Like the CVA306 multi channel-amplifier the circuitry was changed for use with a new tube complement.


CTA305 tube complement:

First version: Serial No: 305001 - 305200

PCB Circuit board marked 305CA1

4 pc. ECC83 /12 AX7


Second version: Serial No: 305201 and forward.

PCB Circuit board marked 305CA2

2 pc. ECC83 / 12AX7 (RIAA Section)

2 pc. 6992 (Line Section)


Note! The ECC83 and the 6922 are not interchangeable tubes. Each version of the CTA305 can only run with its dedicated tube type.


System remote-control: Copland RC102
