Description:
Tube preamp for Marantz 7 boasts mellow sound quality, sweet and natural mid-frequency, strong tube taste.
Carefully tuned M7 has comprehensive performance and good dynamics. The human voice is natural and delicate, the string music is smooth, stretched, and the positioning and image are excellent. The high and low frequencies are extended in place, and the low-frequency dive is deep and powerful without lack of flexibility.
The circuit of our shop is derived from the classic M7 circuit, and the necessary modifications and adjustments are made according to the characteristics of modern devices (mainly coupling capacitors) and old antique capacitors. With our own strength, reasonable layout and wiring, this product has no annoying noise and runs quietly. Dimensions 360x92x308mm (without size of protruding parts).
Designs of many electronic tube preamp on the Internet are not very reasonable, mainly because the distance between tubes is too close. We recommend that the distance between the center of tubes is greater than 40MM.
Package Included:
- 1 x Set of Tube Preamplifier
Note:
- Electronic tubes are not included. Please prepare 3pcs 12AX7 by yourselves.
- It is assembled.
