Replica MARK LEVENSON JC-2 FET Preamplifier Toshiba K170BL/J74BL Sound Mellow and Delicate XLR Input HIFI Preamplifier

Replica MARK LEVENSON JC-2 FET Preamplifier Toshiba K170BL/J74BL Sound Mellow and Delicate XLR input HIFI Preamplifier

Product introduction:
1: This machine is referenced from the front stage line JC-2 of MARK LEVINSON. The circuit of this machine is a fully symmetrical FET input. The voltage level reaches 20MA-25MA Class A output. The FET model is Toshiba K170BL/J74BL:

2: The sound of this machine is mellow and durable, delicate, crystal clear, not comparable to that of OPA627 637. The balance is very good, very close to the style of the courage machine, and the cost performance is very high. Because it is a fully flat symmetrical structure, input and output capacitors can be omitted.

3: The current output stage is added to the original circuit of this device, which can output large current. It is suitable for matching with any fever power amplifier, and even can be used as an ear amplifier!

4: The overall layout of the machine is based on the modern fever concept. Each channel is powered independently, and the fever materials are pleasing to the eye

5: Eight golden German ROE capacitors, very good sound, but because the capacitors have been discontinued, they are used for original board disassembly or inventory. The remark here is clear, and does not affect any quality. The quality of Germany is better than that of Japan.

6: The layout materials of the JC2 balanced version are the same as those of the classic version. Due to the width of the chassis, the rear terminals cannot be placed in many groups. Therefore, the balanced version has only one set of RCA and one set of XLR inputs. The power of power transformers is upgraded from two 15W transformers to two 25W transformers.
