LG135 GoldoxTaurusMtypeEL34Circuit board for push-pull machine：6N3+6N6+EL34，Classic circuit has excellent performance，The sound quality is better than common lines！

EL34Circuit board for superlinear push-pull machine：delicateFR4Double sided fiberglass board，superior qualityPCBplate，Plate thickness2mmNot easy to deform，170×160mm，Plate thickness2mm，Arc routing。Plate thickness2mm，Mark the resistance on the board、capacitance、Voltage parameters，Label interface terminal。

Line adoption6N3+6N6+EL34×2Classical circuit，power2×40W，Excellent performance，Reasonable routing，Just connect the power transformer、Output transformer、Reasonable commissioning，Correct wiring，You can succeed。

The circuit board includes high voltage rectifier lines、Grid negative pressure rectifier circuit。One grid negative pressure regulating potentiometer and one push-pull tube current balance regulating potentiometer。

On boardRP2Grid negative pressure regulation，adjustmentEL34Working electricityflow，measureR16、R17Voltage is0.4Vabout。No electronic tube is inserted before power on commissioning，adjustRP2Make the grid negative pressure(-50Vto-100VUnequal)，bringEL34Working electricityFlow small，security。

On boardRP1It's twoEL34Push-pull tube current balance regulation，Adjust twoEL34Working electricityflow，measureR16、R17Same voltage，All0.4Vabout。Empty plates shall be assembledRP1Adjust to the midpoint position。

RP2andRP1Adjust each other。

LG135 The finished blue board does not contain electronic tubes，Stereo needs two

LG135K Blue boardEmpty board，Stereo needs two

PCB5/3/56

Element foot distance、Pipe base foot distance、The design of foot hole size is reasonable，Suitable for large and small power resistors、capacitance。Two purpose design of electronic tube socket，The resistance capacitance element can be assembled and welded on both sides。

The electronic tube sockets are designed with round foot holes and flat foot holes，Flat pin holes are easier to weld than round pin holes without Tin leakage，Applicable to all kinds of electronic tubesDIYLine use。

The headquarters obtained a number of manufacturers1993year～1995Several Jinniu output transformers produced in、Power transformer，Genuine material。

The output transformer is authentic JapaneseZ11Iron core。Exquisite winding technology and high-quality iron core，The quality is naturally guaranteed。

“GOLDOX”Introduction to Taurus：1990s，Produced by Shenzhen Vickers Electronics Co., Ltd“GOLDOX”TaurusGOXSeries vacuum tube audio amplifier，By the sound industry“Brave warrior”Mr. Zeng Dejun, known as Mr. Zeng Dejun, takes the original high-quality output transformer as the cornerstone，set up“Taurus”Flag，To imitate historical inscriptionsGOX（primaryVAA）Series value、Liangsheng venture machine is welcomed and affirmed by users，GOXThe series has been finalized and produced nearly ten classic products。

“Taurus”Brand all kinds of output transformers have been tested by the Dutch audio authorityAudio FreakSubjective listening evaluation of detection and audio experts，It is universally acknowledged that all performance indexes have reached the world standardYi Liulevel，Quality recognition granted access to the international market。“Taurus”Output transformer and“Jinlong electron tube”Set sail to sea，Famous overseas。

1996Years later“GOLDOX”Taurus changed its name to the current grand ceremony
