Description

Product Description
6H2 full-wave rectifier filter power Finished board 20mA for Tube preamp
6H2 is a new stock item, the input AC voltage can not exceed 280V
Parameters:
Board size: 114 × 76mm
Board thickness 2mm
Single group AC power supply → 2pieces 6H2 to rectify → 2pcs EPCOS 10U500V high voltage capacitor
→ 10H50mA choke → phillips 33U/450V electrolysis, choke center tap 10U400V capacitor,
total four-stages filtering.
Features:
1.
High voltage full-wave rectification and filtering power supply board, choke four-stage filtering
.
2. 6H2 small 7pin feet is a special tube for communication ultra-short wave detection.
The capacitance between the poles is small and the working frequency is high.
3. 6H2 rectifying tube belongs to the vacuum space charge movement mode.
the sound quality is much better.
4. The
tube preamplifier rectifier uses 6H2 circuit
to replace 6Z4, which is a commonly
used low-frequency low-power rectifier. the sound is richful.
5.  Circuit characteristics:
single voltage supply, full wave bridge rectifier filtering,
current 20mA, for preamp use
6. Imported
Z11 used iron core material
for tube output transformer for choke coil!
EI57X30 specification sheet thickness 0.35mm, oxygen-free copper enameled wire wrapped.
Attention:
* 6H2 is a new stock, the input AC voltage can not exceed 280V.
* The color of the board will be different due to the production batch,
the components on the finished
board maybe different as well, including the brands and
specifications.
* The components and parameters on the board will be subject to the real shipment
* Some capacitors on the circuit board are second-hand disassembled products, but all are tested before shipment.
