Product Description

Use imported Panasonic PANASONIC MKP input coupling capacitors, lower distortion, better control and resolution. Single differential input, single-ended voltage amplifier stage, three-stage inverted Darlington output stage.

*The small tube is produced by PHILIPS, and the output stage is imported KTB817, KTD1047;

*ST, CBB capacitor produced by EVOX;

* KEMET, TDK's monolithic capacitors;

*Use imported Panasonic PANASONIC MKP input coupling capacitors;

*All resistors are made of original genuine metal film resistor copper feet;

*Support voltage DC: + －15V to + －45V;

*AC dual 12V- can be obtained after dual 32V rectification;

*Power 15-100W, 8 ohms;

*PCB area 76*73 mm, version number V7 (MX50SE).

Installation note: 649 669 must be installed on the matching radiator.

No adjustment is required after installation. The quiescent current is about 30MA per tube. This version does not require flying wires. Only need to install two big tubes on the radiator.

The luxury version of the finished board is matched with the original imported Sanken, the highest-end model of high-power tube, LAPT series 2SA1295, 2SC3264.
