This price is for the finished tested board, excluding electronic tubes and transformers
PCB size: 155*177*1.6MM FR4 Class A board
The PRT12A preamp is a reference for the CARY-SLP90 circuit.
The SLP90 is the first of a series of triode preamps from CARY and has been very well received. Unlike conventional preamps, the SLP90 is
The SLP90 has a high level of detail and thickness in the lower midrange.
The PRT12A is grounded at one point and has a quiet, noise-free back.
The high voltage power supply is stabilised by a Toshiba K2700 field effect tube as a high voltage power supply regulator.
Filament power supply uses one in and two out regulated method to power the left and right channels respectively
Configuration: High voltage filtering using Hitachi electrolytic capacitors, chemical high voltage decoupling capacitors, Taiwan-made 3W 1% precision metal film resistors, silver-plated ceramic tube holders, Spectrum and MKP coupling capacitors, with good value for money.
On the upgrade of the mill program: the quality of the electronic tube has a great decisive role, it is recommended that the budget to choose a high-grade bile tube, in addition, can consider upgrading the replacement of coupling capacitors, such as MCAP, etc.
This version uses four 12AU7 tubes, all working in parallel.
